Introduction

Chapter 1, “Introduction”, describes the operating features of the XW Hybrid Inverter/Charger.

Topics in this chapter include:

• “Basic Features” on page 1–2

• “Basic Operation” on page 1–3

Introduction

1–2 975-0385-01-01

Basic Features

The XW Hybrid Inverter/Charger is a true sine wave inverter/charger that can be used for residential and commercial applications: stand-alone, grid-backup, and grid-tie with battery energy storage. Capable of being grid-interactive or gridindependent, the XW Inverter/Charger will operate with generators and renewable energy sources to provide full-time or backup power.

Other XW Inverter/Charger features include:

• High efficiency true sine wave output

• Buildi ng blo ck power lev e ls—Up to three inverters can be installed together in a 230 volt, single-phase, two-wire configuration to produce up to 18 kilowatts. Multiple units can also be connected to create a three-phase system. At least one inverter per phase is required, and up to two inverters can be connected in parallel on each phase.

• Surge capacity to start difficult loads like well pumps, refrigerators or A/C compressors

• Power factor-corrected (PFC) input minimizes AC input current required for charging, increasing AC pass-through capacity

• High DC output current and multi-stage charger minimize charging time

• Optional XW Automatic Generator Start allows operation with a wide range of generators, supported through a dedicated generator in put

• Supports multi-mode grid-tie operation

• Integrated transfer switch

• Temperature-controlled, variable-speed internal cooling fan. The fan turns on when the internal temperature reaches 45 °C and reaches maximum speed at 70 °C. The fan turns off when the internal temperature falls to 40 °C.

• Housing design promotes vertical air flow through the inverter. This natural “chimney effect” provides convection cooling at lower power levels, and reduces fan run time.

• Designed for reliability and field serviceability.

System component

The XW Inverter/Charger uses Xanbus™, a network communications protocol developed by Xantrex, to communicate its settings and activity to other Xanbusenabled devices. You can configure and monitor the XW Inverter/Charger and every Xanbus-enabled device in the system using an XW System Control Panel (part number 865-1050).

Basic Operation

975-0385-01-01 1–3

Basic Operation

The XW Hybrid Inverter/Charger is a modular “building block” sine-wave inverter/charger that can be used for both residential and commercial stand-alone, grid-backup, and grid-tie applications with battery energy storage. The XW Inverter/Charger is a self-contained DC to AC inverter, battery charger and integrated AC transfer switch. All configurations must comply with local and national electrical codes.

Multi-unit operation Inverting For multiple XW Inverter/Chargers, the master inverter/charger

broadcasts pulses on the Xanbus network to synchronize operation between the other paralleled units. When AC loads are present, all units produce power, effectively sharing the load. Multiple XW Inverter/Chargers do not produce power together when Search mode is enabled. See “Using Search Mode” on page 3–8.

Parallel charging Multiple XW Inverter/Chargers synchronize charging stages to ensure efficient charging of the battery bank. All units transition from bulk to absorption when a single unit does. In absorption, all units must complete the absorption stage before transitioning to the next stage. Note that units do not load share when charging except during the Bulk stage. The XW Inverter/Chargers stop sharing charge current just before completing the Bulk stage. The units do not share charge current during the Absorption and Float stages.

Each unit charges batteries based on the Max Charge Rate setting and active internal (temperature-based) deratings.

If equalize is enabled on one or more devices capable of equalization charging (such as XW Inverter/Chargers or XW Solar Charge Controllers), only those devices perform a equalize cycle after absorption. Other devices transition to float (if three-stage charging is selected) or transition to AC pass-through (if two-stage charging is selected).

When one or more XW Solar Charge Controllers are installed and operating in the system, the XW Inverter/Chargers synchronize charging stage (bulk, absorption, or float) with the charge controllers. In a similar fashion to the XW Inverter/ Charger charge behavior, charge controllers also harmonize charging among themselves.

AC Transfer XW Inverter/Chargers monitor each other using a peer-to-peer monitoring technique to determine the quality of AC input. If AC input is deemed bad by any of the paralleled units, no transfer to AC occurs and the AC LED may continually flash on each unit’s Information Panel. If the system was in passthrough and AC fails on any unit, all units transfer to invert simultaneously.

Faults When an XW Inverter/Charger in a multi-unit system has a fault, only the affected device shuts down, except in the following cases:

• When a master unit has an invert mode fault that causes it to stop inverting, a system wide fault occurs. Invert mode faults on a slave unit shut down only the affected slave unit.

• Battery-related faults such as battery over-temperature or over-voltage.

Other modes of operation XW Inverter/Chargers operate independently when in grid support mode (including sell mode), load shave, generator support and charger block modes. This enables units to be configured to perform multiple functions independently and allows greater flexibility in operating the system. All configurations must comply with local and national electrical codes.

Auxiliary output Each XW Inverter/Charger has one programmable auxiliary output that is able to

run a small 12 V fan or operate an external relay to perform other functions, such as to remotely start a generator (if the Xanbus-enabled XW-AGS is not used), to disconnect external non-critical loads, or to turn on a diversion load for battery voltage regulation.

Transfer relay The built-in transfer relay is rated for 60 amps. When an external AC source is

detected on either of its two AC inputs, the switch transfers loads from the XW Inverter/Charger to the external power source, and then activates the battery charger.

AC1 and AC2 relay The XW Inverter/Charger design does not allow the AC1 and AC2 inputs to feed

into each other. The relays controlling AC1 and AC2 input can never close simultaneously. This design prevents generator input from backfeeding to the utility grid.

Surge Performance

Unlike many other inverters, the XW Inverter/Charger prevents voltage from sagging dramatically during surge conditions. The XW Inverter/Charger handles surges of over twice the inverter’s rated output with only a minimal drop in output voltage.

Islanding Protection

Islanding protection is an essential safety feature that ensures no person working on the utility grid is harmed by a distributed energy source, such an XW Inverter/ Charger. Islanding protection also prevents loads connected to the inverter from being damaged by fluctuating utility grid input.

The XW Inverter/Charger uses a proprietary positive feedback control to achieve reliable anti-islanding while maintaining low total harmonic distortion. Default software settings are programmed into each XW Inverter/Charger at the factory to ensure it does not “island” according to applicable safety regulations.

In some instances it may be desirable from both a utility and customer point of view to adjust default anti-islanding settings. For example, the XW Inverter/ Charger may experience “nuisance trips” if the grid is weak and the voltage falls outside the allowable range specified in the regulations. It may be difficult for a utility to upgrade the grid to eliminate this problem. With permission from the utility, the factory settings may be changed to allow the XW Inverter/Charger to operate over a wider grid voltage range. These settings should only be changed by qualified service personnel, using a special software application provided by Xantrex. All configurations must comply with local and national electrical codes.

While selling power, the XW Inverter/Charger continuously monitors utility grid voltage and frequency. If the grid voltage and frequency move beyond the XW Inverter/Charger default ranges

—during a power surge or outage, for example— the XW Inverter/Charger stops selling power to AC1 and disconnects from the utility grid for five minutes. (Five minutes is the minimum reconnect time, and is not adjustable.) If the utility grid voltage and frequency have returned to their nominal values when the reconnect time has expired, the XW Inverter/Charger begins selling power again.

The Fault light on the XW Inverter/Charger Information Panel indicates a utility fault. No fault code appears on the three-character display because the fault is with the utility grid, not the XW Inverter/Charger.

The XW System Control Panel (SCP) indicates a utility fault with the Fault light and a fault message on its screen (faults F23 to F37 are utility faults—see Tabl e 45 on page 4–18). The fault cannot be manually cleared. Utility faults clear automatically when the utility grid voltage and frequency return to within the ranges programmed into the XW Inverter/Charger.

Monitoring Faults and Warnings

The red Fault/Warning LED indicates the presence of a fault or warning in the system. To clear active faults, press the On/Off button momentarily.

Equalizing Batteries

Button Pressing the Equalize button (indicated by the symbol) for five seconds turns

battery equalization on and off. After this button is pressed, the XW Inverter/ Charger begins the equalization charge after the next charge cycle is complete. Equalization functions only if AC is present and qualified and the charger is enabled. Otherwise the inverter/charger generates a “cannot equalize” fault (W96).

For more information, see “Equalize Charging the Batteries” on page 3–12.

LED The yellow Equalize LED indicates that the XW Inverter/Charger is equalizing

batteries.

Symbol LED On LED Flashing

The XW Inverter/Charger has a fault and has stopped charging or inverting. The LED also turns on steadily if the unit has both a fault and a warning.

The XW Inverter/Charger has a warning. A warning may escalate to a fault if the warning condition does not go away.

CAUTION: Battery damage

If improperly performed, equalization can damage your battery. Consult your battery supplier for details on equalizing the battery type in your system.

Important:

In a system where more than one device is capable of equalizing batteries (such as a system including multiple XW Inverter/Chargers and Solar Charge Controllers), there is no system-wide equalization command for all devices. To equalize with multiple devices, each would have to be enabled individually. Alternatively, equalization can be performed using only one device. During the equalization process, one device applies the equalization charge while the other devices continue to operate in synchronized charge mode, typically in float (three-stage charging) or no-float (two-stage charging).

Symbol LED On LED Flashing

The XW Inverter/Charger has begun equalizing the batteries.

Equalization has been enabled but has not begun. The XW Inverter/Charger must complete a charge cycle before applying the equalization charge.

Turning the XW Inverter/Charger On and Off

On/Off control When the XW Inverter/Charger is operating, pressing and holding the On/Off

button (#) for five seconds turns the unit off. To return the XW Inverter/Charger to its previous operating state, press the On/Off button momentarily.

When the XW Inverter/Charger is being turned off, the other Inverter Information Panel buttons stop working. The shutdown process cannot be cancelled. The XW Inverter/Charger can only be turned back on once the display is blank.

Standby mode In Standby mode, the XW Inverter/Charger stops ch ar ging, in verting, and passing

through AC input. However, the unit remains powered up and present on the Xanbus network.

To put the XW Inverter/Charger into Standby mode, press and hold the On/Off button and the Equalize button simultaneously for about five seconds. The display shows “Stb.” To return the XW Inverter/Charger to operating mode, press the On/ Off button momentarily.

Pressing the On/Off button momentarily while the XW Inverter/Charger is operating clears active faults and warnings.

Single-unit installations

In a single-unit installation, when the XW Inverter/Charger is turned off using the On/Off button, Xanbus network power is lost. When Xanbus network power is lost, network-connected accessories such as the Automatic Generator Start (XWAGS) and XW System Control Panel lose power and stop operating. XW Charge Controllers continue to operate and communicate between each other if Xanbus network power is removed.

Multiple-unit installations

If the On/Off power button is pressed and held on a master XW Inverter/Charger (see “Inverter Mode” on the “Multi-Unit Config Menu” on page 3–23) and an XW-AGS is installed in the system, the unit stops inverting or charging immediately and turns off completely in 120 seconds. During this time, the display shows “OFF.” This interval allows the XW-AGS to stop the generator after a “cool down” period. During the 120-second shutdown time all network communication is blocked and the unit sends a shutdown command to all other devices in the system. As well, the Inverter Information Panel buttons stop working and the shutdown process cannot be cancelled. The XW Inverter/Charger can only be turned back on once the display is blank.

In a multiple-unit installation, when a slave XW Inverter/Charger is turned off, other XW Inverter/Chargers continue to supply Xanbus network power and the XW-AGS and XW System Control Panel continue operating.

Monitoring Operation

2–6 975-0385-01-01

Monitoring Battery Level

The row of five LEDs indicates the approximate available capacity of the batteries connected to the system. The capacity reading is based on current-compensated battery voltage.

There are four battery states: empty, low, medium, and full. When the available battery capacity is empty, no LEDs are lit. The battery is considered empty when its depth of discharge exceeds approximately 50 per cent. When the battery capacity is low, the leftmost two LEDs are lit. When the battery is at medium capacity, the leftmost four LEDs are lit. When the battery capacity is full, all five LEDs are lit.

Reading the Display Screen

The three-character display screen shows the following information about the operating state of the XW Inverter/Charger:

• Output power in kilowatts when the XW Inverter/Char ger is inverting and the

kW LED is lit.

• Battery charger current when the XW Inverter/Charger is charging and the

A LED is lit.

• “Stb” when the XW Inverter/Charger is in Standby mode.

• “Sch” when the XW Inverter/Charger is in Search mode. See “Using Search

Mode” on page 3–8 .

• “OFF” when the on/off button is pressed and held for five seconds. “OFF” is

displayed briefly before the unit turns off.

• “– – –” briefly when the XW Inverter/Char ger is in transition between modes,

for example, qualifying AC input. The display also shows “– – –” when the XW Inverter/Charger has been manually disconnected from renewable energy power sources and is operating in bypass mode.

• “En” momentarily when the inverter is enabled.

• “dIS” momentarily when the inverter is disabled.

XW Inverter/ Charger Status Displayed When...

Invert The XW Inverter/Charger is supplying power to loads by inverting power from the batteries. AC

input from the utility or generator is absent or out of nominal range.

Qualifying AC The XW Inverter/Charger is determining if AC input is within a usable voltage and frequency

range. “Qualifying AC” is also displayed when the XW Inverter/Charger is awaiting application of AC power or a command to enable invert mode.

Charging The XW Inverter/Charger is charging the batteries from qualified AC input from the utility grid

or a generator. The charge state is in transition to either Bul k, Absorp tion, Fl oat or Equal ize. AC input is also passed through to the load while charging.

Bulk The XW Inverter/Charger is bulk charging the batteries from qualified AC input from the utility

grid or a generator. AC input is also passed through to the load while bulk charging.

Absorption The XW Inverter/Charger is absorption charging the batteries from qualified AC input from the

utility grid or a generator. AC input is also passed through to the load while absorption charging.

ABS Finish The XW Inverter/Charger has completed the absorption stage and is waiting for other chargers

in the system to complete absorp tion. This stat us can occur only when there is another device (an inverter/charger or charge controller) also charging the battery.

Float The XW Inverter/Charger is float charging the batteries from qualified AC input from the utility

grid or a generator. The XW Inverter/Charger is set for three-stage charging. AC input is also passed through to the load while float charging.

CHG Finish The XW Inverter/Charger has completed charging or the charge cycle has been interrupted and

is transitioning to the next state. This stage last about one minute, while the battery is allowed to settle. The delay keeps the inverter/charger from unnecessarily transitioning to Grid Support (if enabled) after a charge cycle.

Fault The XW Inverter/Charger has an active fault. The Fault/Warning light on the System Control

Panel is on.

Gen Support There is AC input from the generator, and the XW Inverter/Charger is supporting the generator

by supplying additional power to the critical loads. The XW Inverter/Charger supports the generator (or other power source connected to the AC2 input) when the AC load current drawn from AC2 exceeds the GenSup Amps setting for 1 to 2 seconds. The XW Inverter/Charger uses stored DC capacity to load share with the generator until the total AC load current (generator plus inverter output) drops by 2 amps plus 10 per cent of the GenSup Amps setting for 6 seconds. For example, if GenSup Amps is set to 10 amps, t he inverter starts to support when the load exceeds 10 amps for 2 seconds and stops when it drops more than 3 amps below the GenSup Amps setting, or 7 amps (2 amps plus 10 per cent of 10 amps = 3 amps). The system can enter this state if the battery voltage is above the Low Batt Cut Out setting and Gen Support is enabled. See “Generator Support Settings” on page 3–20.

975-0385-01-01 2–13

Reading the Meters Screen

The Meters screen displays total system power production, grid voltage and current status, and load voltage and current status.

To view the Meters screen:

◆ On the XW Inverter/Charger setup menu, highlight “Meters” and press Enter.

Grid Support There is AC input from the utility and the XW Inverter/Charger is supporting the utility grid by

supplying additional power to the critical loads. The XW Inverter/Charger supports the utility grid by limiting the power drawn from the utility to less than 10 per cent of the load demand. This mode is desirable for using excess energy from auxiliary DC sources like PV, while still maintaining a charged battery bank. No power is sold to the utility in this mode. The XW Inverter/Charger enters this state only when the Grid Support is set to “On” and battery voltage is above the Grid Supp Volts setting. See “Grid Support Settings” on page 3–16.

Load Shaving There is AC input from the utility, and the XW Inverter/Charger is supporting the utility grid

when the current required to power the loads rises above the Load Shave Amps setting between the Load Shave Start and Load Shave Stop times set on the Grid Support menu. Many utilities impose a surcharge on their customers based on the peak load used by a facility. When load shaving, the XW Inverter/Charger uses stored DC capacity to reduce the peak load on the utility grid and keep current draw from the grid equal to or under the Load Shave Amps setting. The XW Inverter/Charger enters this state only when Grid Support is enabled, the Load Shave time window is valid and the load draw exceeds the Load Shave Amps setting. See “Grid Support Settings” on page 3–16.

Search Search Mode is enabled and the XW Inverter/Charger is standing by , waiting to begin inverting.

See “Using Search Mode” on page 3–8.

SellToGrid The XW Inverter/Charger is grid tied and selling power to the utility grid. Both Grid Support

and Sell must be enabled in order to sell power back to the utility. See Table 3-1 on page 3–2 and “Grid Support Settings” on page 3–16. All configurations mu st comply with local and national electrical codes.

Standby The unit has been placed in Standby mode using the “Mode” setting on the SCP Setup menu or

the Standby button on the SCP or using the Standby key press (On/Off and Equalization) on the Inverter Information Panel.

Passthru The AC connected to the AC1 or AC2 input is passing directly through the XW Inverter/Charger

to the loads. The batteries are not being charged in this state.

Equalize Equalization has been turned on and the XW Inverter/Charger is equalizing the batteries after

completing a full charge cycle.

Inverter Settings Menu

The Inverter Settings Menu contains settings that control when the XW Inverter/ Charger turns on and off while inverting.

For default settings, see “Inverter Menu” on page B–3.

Using the Low Battery Cut Out and LBCO Delay Settings

The Low Batt Cut Out setting is the lowest battery voltage level acceptable for use by the inverter. When the batteries discharge to the Low Batt Cut Out setting, and are held at or below this level for the LBCO Delay time, the inverter output shuts down and transfers any available AC source (generator or grid) to the charger to bring the battery level back above the Low Batt Cut Out setting. After shutdown, the inverter does not support any AC loads, and AC loads must be powered by either a generator or grid power.

Table 3-2

Inverter Settings menu

Item Description

Low Batt Cut Out

This setting controls when the inverter turns off due to a low battery voltage condition. The inverter will turn off only after this level has been reached for the period of time set by the LCBO Delay. This setting is not temperature compensated.

LBCO Delay

LBCO Delay controls how long the inverter is allowed to operate at or below the Low Battery Cut Out level before turning off due to a low battery voltage condition. The inverter will turn off only after the Low Batt Cut Out level has been reached for this uninterrupted period of time. Once the inverter has shut off, the battery voltage must rise 2 volts above the Low Batt Cut Out setting (1 volt for 24 V systems) for inverter operation to resume.

High Batt Cut Out

High Batt Cut Out sets the maximum battery voltage at which the inverter will operate. If the battery voltage exceeds this limit for more than 1 minute, the inverter displays a fault message (F49) and shuts down. The inverter will not support AC loads when in this condition. If a qualified AC source is present, the unit passes AC through to the loads. The inverter automatically restarts when the voltage drops to 3 volts (24-volt system) or 6 volts (48-volt system) below the High Batt Cut Out setting. If battery voltage continues to rise after shutdown, an external charger may still be charging the batteries. The XW Inverter/Charger cannot control how external chargers operate.

Search Watts

Search Watts sets the inverter’s search sensitivity when Search mode is enabled. When a load larger than this setting is present, the inverter turns on. Enabling Search mode from the Setup Menu (see page 3–2) can minimize power draw from the battery during periods of low demand from loads. Also see “Using Search Mode” on page 3–8.

Search Delay

Search Delay sets the time between search pulses. When searching for loads, the XW Inverter/Charger sends out search pulses to determine if a load is present. If the XW Inverter/Charger finds a load above the Search Watts setting, the inverter comes on. XW Inverter/Charger power draw while in Search mode decreases when Search Delay is increased, but the inverter’s response time to active loads is reduced.

Configuration

3–8 975-0385-01-01

If using an automatic generator starting system, it is recommended to set the AGS voltage trigger setting higher than the XW Inverter/Charger Low Batt Cut Out voltage. Otherwise, inverter output turns off before the generator automatically starts, causing the battery voltage to recover slightly. This may then stop the AGS from starting the generator or result in the inverter cycling on and off multiple times before the generator automatically starts.

If using an automatic generator starting system with the start trigger set to the same voltage as the LBCO voltage, do not set the LBCO Delay for less than the amount of time it takes the generator to start and connect. Otherwise, inverter output turns off before the generator automatically starts, causing the battery voltage to recover slightly. This may then stop the AGS from starting the generator or result in the inverter cycling on and off multiple times before the generator automatically starts.

Using Search Mode

Why use Search mode?

Search mode allows the inverter to selectively power only items that draw more than a certain amount of power, which can result in power savings.

The XW Inverter/Charger has a no-load power draw of about 28 watts. Enabling Search mode reduces this power draw to less than 8 watts.

Search mode operates differently in single-unit and multi-unit installations.

Single units When a single XW Inverter/Charger has Search mode enabled, the inverter sends

electrical search pulses through its AC output. These search pulses “look” for connected AC loads. The delay between search pulses is set using the Search Delay setting.

After a load larger than the Search Watts setting is detected, the inverter turns on.

Multiple units To use Search mode in multiple-unit installations with paralleled XW Inverter/

Chargers, the master unit must have Search mode disabled. Slave units must have Search mode enabled.

When Search mode is disabled on the master unit and Search mode is enabled on slave units, only the master XW Inverter/Charger operates, and the slave units come on-line only when the load exceeds approximately 60 per cent of the rated output of the master unit. In a three-unit system, the third slave unit turns on if the load on the master does not drop below 60 per cent about 3 to 5 seconds after a slave unit turns on to assist the master. When the load drops below 20 per cent of the master’s rated output, the slave units turn off in reverse order; that is, the last slave unit to turn on is the first to turn off.

When to set up Search mode

The Search mode feature is only valuable if the inverter can spend a fair amount of time “sleeping” each day. Therefore, if Search mode is to be utilized it must be adjusted properly. The initial adjustment should be made so that the inverter comes on only when needed.

Certain types of loads can cause Search mod e n ot to w ork as expected. These types of loads are described on page 4–3 of the Troubleshooting chapter. If these kinds of loads are in the system, follow the suggestions given to eliminate the problem.

Charger Settings Menu

975-0385-01-01 3–9

If the problem loads cannot be eliminated, there are two work-around solutions:

1. Disable Search Mode from the main XW Inverter/Charger Setup menu, causing the inverter to always remain at full output voltage.

2. Use a search-friendly “companion load” whose only purpose is to be switched on to “wake up” the inverter to power the load that is unable to bring the inverter out of Search mode.

Charger Settings Menu

The Charger Settings menu gives you options for configuring the XW Inverter/ Charger to operate from your battery bank.

Notes:

• Search mode, by function, cannot work with clocks and timers or devices that need

power 24 hours a day. Examples of devices with timers include video recorders, coffee makers with brew timers, refrigerators, and freezers with defrost timers. Examples of devices that need power 24 hours a day include telephone answering machines, alarm systems, motion detection lights, and some thermostats.

• When the inverter is searching the output for loads, lights that have a wattage lower

than this setting may flash momentarily.

Battery Charger Functions

Whenever AC is present on the XW Inverter/Charger input, the unit can operate as a battery charger. Different battery types and chemistries require different charging voltage levels. Not charging batteries at the required levels can sho r ten battery life or damage the batteries. The XW Inverter/Charger is configured at the factory to work with the battery types recommended for inverter applications. If the default settings do not work for your specific installation, you can adjust the charge stage settings (as recommended by the battery manufacturer) on the Custom Battery Settings menu (see page 3–14).

Multi-Stage Charging Process

The charging cycle is a multi-stage process. Whenever qualified AC power is present at the inverter’s input, it passes power through to the connected load and begins charging the batteries.

Chg Block Start Sets the time to halt charging on AC1 (Grid). The AC2 (Gen) port is

unaffected by the Charger Block settings. The Charger Block Start and Stop settings allow you to select when the charger stops charging on AC1. T o disable the Charger Block function, set Chg Block Start and Chg Block Stop to the same time. See “Using Charger Block” on page 3–13.

Chg Block Stop Sets the time that charging on AC1 can resume. At the Chg Block

Stop time, charging on AC1 is enabled again.

Bulk Stage Bulk charge is the first stage in the charging process and provides the batteries

with a controlled, constant current. Once the battery voltage rises to the bulk voltage threshold, the charger switches to the Absorption stage.

Absorption Stage Absorption charge is the second stage of battery charging and provides the

batteries a controlled, constant voltage. During this stage, the current supplied to the batteries slowly decreases. When this current falls below 2 per cent of the battery capacity, or when the configurable Absorb Time e xpires, the charger switches to the Float or NoFloat stage, depending on the selected charge cycle.

Float Stage Float charge maintains a trickle charge on the batteries whenever AC is present on

the XW Inverter/Charger input. Float charging reduces battery gassing, minimizes watering requirements (for flooded batteries), and ensures the batteries are in a constant state of readiness. When three-stage charging is selected, the charger automatically switches to the float stage after the batteries have received a bulk and absorption charge (see Figure 3-4 on page 3–10). The batteries will be maintained at the default float voltage level for the selected batte r y type or the voltage selected under Float Voltage on the Custom Battery Settings menu.

T wo-Stage T wo-stage (or No Float) mode differs from an ordinary three-stage charge mode in

that it does not continuously maintain the battery at float voltage. Instead, the XW Inverter/Charger begins charging the battery in bulk mode whenever the battery voltage drops below the recharge level. While the battery voltage is above the recharge level the inverter’s AC transfer switch continues to pass power through from the utility grid to the loads, but does not actively charge the batteries. Twostage mode increases efficiency of utility connected systems by reducing the amount of power consumed by the inverter and batteries compared to when the battery is continuously maintained at Float voltage. This feature can extend the life of most batteries.

To allow Grid Support and Sell Mode to function after battery charging has completed, it is recommended to set the Charge Cycle to two-stage.

Note: If there are DC loads on the batteries, the charger’s current may never decrease

to a level to initiate the next stage of charging. In this case, the charger would stay in absorption until the Absorb Time setting is reached. To ensure the charger does not rema in in absorption for too long, adjust Absorb T ime on the Charger Settings menu. The timer begins at the start of the absorption stage and terminates absorption charging if the charge current does not decrease to below 2 per cent of the battery capacity before the Absorb Time setting expires. The Absorb Time setting may be increased if the charge cycle continually runs the full Absorb Time in the absence of DC loads. This is an indication of too large a battery bank for the selected Absorb Time setting.

Note: The battery voltage can increase above the float voltage when using an external

charging device such as PV arrays, wind turbines, and micro-hydro generators. Be sure to include appropriate charge management equipment with all external DC sources.

Configuration

3–12 975-0385-01-01

Equalize Charging the Batteries

Many battery manufacturers recommend periodic equalize charging to level out the voltage between individual cells, improving battery performance and lifespan.

Over time, the battery’s electrolyte can become “stratified,” causing inactive areas in the plate material. If this condition is allowed to continue for extended periods, the battery plates can “sulfate” and become unusable. Equalizing the batteries is a controlled overcharging method that mixes up the electrolyte and reactivates the unused areas of the plate material, restoring batteries to a full state of charge.

Consult the battery manufacturer’s recommendation for equalize charging settings.

To start equalizing the batteries:

◆ On the XW Setup menu, highlight Equalize and select Enable.

-OrPress the equalize button on the Inverter Information Panel for five seconds.

Note: If the AC input fails or drops below the lower V ac limit (as set in “AC Settings”),

the complete multi-stage charge cycle (Bulk, Absorption, Float/No Float) restarts once the source AC returns to an in-tolerance condition. If the batteries are already nearly full, the charge cycle will take little time to complete.

Using Charger Block

The Charger Block feature halts charging on AC1 (Grid) for a period of time each day. This period of time is defined by the Chg Block Start and Chg Block Stop settings. In areas where the utility charges variable rates for electricity, it is preferable to use utility power for charging only during non-peak hours. Charger Block can prevent utility power from being used for battery charging during peak billing periods.

During the time period set between Chg Block Start and Chg Block Stop, AC1 (Grid) input continues to be passed through to the loads. Inverter operation remains unaffected during the charger block period.

During the Charger Block period, no char ging on AC1 occurs even if the batteries discharge below ReCharge Volts setting. However, a generator connected to AC2 (in the absence of utility/AC1 power) or an XW Solar Charge Controller may charge batteries during the Charger Block period. AC priority must be set to AC2 to charge batteries with a generator connected to AC2 during the Charger Block period.

If the charger is operating (that is, in Float, Absorption, Bulk or Equalize stage) at the Chg Block Start time, charging on AC1 stops immediately and the charger enters an idle state identical to No Float (see “Two-Stage” on page 3–11). When the Charger Block period is over, the charger does not resume the charge stage that Chg Block Start interrupted. Instead, if the batteries are above the ReCharge Volts setting, the charger remains idle.

If the battery voltage falls below the ReCharge Volts setting during the Charger Block period, the XW Inverter/Charger begins a new charge cycle with the Bulk stage after the Charger Block period has expired (at the Chg Block Stop time).

For example, Charger Block is set to start at 5:00 PM and end at 8:00 PM. If the XW Inverter/Charger is charging from AC1, charging stops at 5:00. When Charger Block ends at 8:00, the XW Inverter/Charger does not automatically resume charging. The unit first measures the battery voltage. If the voltage is below the ReCharge Volts setting, then the XW Inverter/Charger starts a new charge cycle from Bulk. If the battery voltage is above the ReCharge Volts setting, the XW Inverter/Charger remains idle and continues passing through AC to the loads. The XW Inverter/Charger also keeps measuring the battery voltage as before to determine whether to start a new charge cycle.

AC Settings

The AC Settings menu configures the voltage and frequency limits for AC line 1 (grid) and AC line 2 (generator). These are the limits at which the XW Inverter/ Charger considers input voltage qualified—that is, suitable for charging batteries or powering loads. If the input voltage is not qualified according to these settings, the XW Inverter/Charger transfers from using AC input to inverting.

For default settings, see “AC Menu” on page B–4.

Table 3-5

AC Setting s menu

Item Description

AC Priority Sets the priority for the AC source (AC1 or AC2) for qualification and

transfer. For example, this setting allows the XW Inverter/Charger to us e a renewable energy source (such as an AC hydro generator) connected to AC2 on a first-priority basis and use utility power only when renewable energy is insufficient or unavailable to power loads.

In systems that use both utility grid (AC1) and generator (AC2) input, AC Priority is recommended to be set to AC2. Assuming the generator is intended for occasional use only, the XW Inverter/Charger will use utility power until the generator is started.

AC1 Breaker Sets the AC1 (Grid) breaker size, based on the size of the breaker

installed on AC1. The installed breaker size must not exceed the capacity of the upstream distribution panel. The XW Inverter/Charger limits the maximum input current to this setting by derating its charging current. If the connected loads exceed the AC1 breaker setting, the AC breaker trips. The breaker may not trip if Grid Support is enabled and battery voltage is above the Grid Support Volts setting, or if Peak Load

Shave is enabled and the Load Shave Time window is active. AC1 Lo Volt Minimum acceptable input voltage level from the utility grid. AC1 Hi Volt Maximum acceptable input voltage level from the utility grid. AC1 Lo Freq Minimum acceptable utility grid input frequency. AC1 Hi Freq Maximum acceptab le utility grid input frequency. AC2 Breaker Sets the AC2 (Gen) breaker size, based on the size of the installed AC

Grid Support Settings

The Grid Support Settings menu contains configuration options for grid-tie operation. To enable all these settings, Grid Support must be enabled in the Setup menu (see “XW Inverter/Charger Setup Menu” on page 3–2).

Important:

Grid support and Sell functions are modes of operation that are subject to local and/or national grid interconnection requirements in most jurisdictions. It is the responsibility of the installer and system operator to ensure that all applicable procedures and technical requirements are complied with before turning on either of these modes. The interconnect codes and standards with which the XW Inverter/Charger complies are listed in the Specifications section on page A–8.

Note: Upon startup, the XW Inverter/Charger does not enable Grid Support functions

for five minutes (300 seconds). During this period the XW Inverter/Charger connects to AC input and determines whether the utility grid voltage and frequency are stable and within nominal range. If Grid Support is enabled, the Inverter Information Panel also displays a 300-second countdown during this period. For more information, see “Islanding Protection” on page 1–5.

Sell Turns Sell mode on and off. When Sell is enabled, the XW

Inverter/Charger AC output is divided between powering loads and delivering power to the utility grid. Sell mode requires the battery voltage to be above the Grid Supp Volts. All configurations must comply with local and national electrical codes.

Max Sell Amps Sets the maximum AC amps allowed to be delivered to the utility

grid from a solar array and/or the batteries during grid-tie operation. This setting is only used if Sell mode is enabled. The Max Sell Amps must be less than 80 per cent of the selected AC1 breaker setting. If set higher, the breaker setting will override the Max Sell Amps setting to avoid tripping the breaker.

Load Shave Enables or disables the Load Shave feature. Load Shave allows the

XW Inverter/Charger to support the grid in powering local loads during a defined window of time (set using Load Shave Start and Load Shave Stop). When in this mode, the XW Inverter/Charger operates until the batteries discharge to the LBCO threshold, after which the unit reverts to AC pass-through. The charger is automatically blocked during the Load Shave time window.

For default settings, see “Grid Support Menu” on page B–5.

Energy Management

The XW Inverter/Charger can be programmed to control how and when to use utility power. Advanced features allow management of peak loads and time-ofuse billing.

Charger Block

See “Using Charger Block” on page 3–13.

Grid Support

The Grid Support feature allows the XW Inverter/Charger to support local loads by converting excess capacity from external DC sources connected to its battery bank. Examples of external DC sources are charge controllers, micro-hydro, and wind turbines.

For Grid Support to function, Grid Support must be enabled on the Setup menu and the battery voltage must be above the Grid Supp Volts setting.

There are two modes of operation within Grid Support. Grid Support enabled, Sell disabled In this mode, available excess DC power

is converted and used to power local loads. No power is exported to the utility. If the local load demand exceeds the available power from the external DC sources,

Load Shave Amps Sets the maximum amount of current that can be drawn from the

AC1 (grid) input by the loads and battery charger combined. This setting determines the amperage level at which the inverter starts drawing power from the batteries to add to the utility power to meet the demand of the loads. Typically, this value is set to the size of the AC circuit breakers feeding the inverter’s AC input.

Load Shave Start Sets the time of day that the Load Shave feature operates. This

feature is suited for regions where local utilities impose peak usage surcharges. The inverter provides load shaving power as long as battery voltage is above the Low Batt Cut Out setting.

Load Shave Stop Sets the time of day that the Load Shave feature stops operating. If

Load Shave is enabled and Load Shave Start and Load Shave S top are set to the same time, the XW Inverter/Charger load shaves continuously.

Table 3-6

Grid Support Settings menu

Item Description

Important:

Configuration

power is then drawn from the utility to support the load. However, if the local load demand is less than the power available from external DC sources, the net excess power from the external DC sources is not converted and hence not used.

Grid Support enabled, Sell enabled In this mode, all available excess DC power is first used to power local loads. Any remaining power is exported to the utility grid.

Grid Support and Battery Charging

Charge Cycle settings

With the charger enabled, the XW Inverter/Charger enters Grid Support mode only after completing a charge cycle when it is first powered up or reconnected to the grid. It is recommended to set the Charge Cycle to 2-stage (default) to allow Grid Support to function immediately after the Absorption charge stage. See “Charger Settings Menu” on page 3–9.

Grid Support modes Grid Support can be configured to operate in one of two modes.

Fixed battery voltage This mode is suitable for systems with DC sources that are not connected to the XW Inverter/Charger through Xanbus or mixed systems which have both Xanbus connected XW Solar Charge Controllers and other DC sources. In this mode, the Grid Supp Volts setting is set about 0.5 volts below the voltage provided by the DC source (typically the float voltage setting of the DC source or charge controller).

In fixed battery voltage mode the XW Inverter/Charger tries to regulate the battery voltage to the Grid Supp Volts setting by converting the available DC power to AC power to support the loads or export to the utility grid. Because the battery bank voltage may not reach Bulk/Absorption voltages in this mode, it is recommended to occasionally force a full charge cycle by either temporarily disabling Grid Support or forcing a Bulk charge cycle from the grid (see “Force Chg” on the “XW Inverter/Charger Setup Menu” on page 3–2).

Enhanced interactive mode This mode is suitable for XW Systems with only XW Solar Charge Controller(s) networked to XW Inverter/Charger(s) through Xanbus. In this mode, the Grid Supp Volts setting is set above the charge controller’s Bulk and Absorb voltages (for example, 32 volts on a 24-volt system and 64 volts on a 48-volt system).

In enhanced interactive mode the XW Inverter/Charger automatically tracks the XW Solar Charge Controller voltage as it transitions through all charge states (from Bulk to Absorb to Float). This allows the XW System to execute a full battery charge cycle while still converting excess DC power to AC power to support the loads or export to the utility grid. Since this mode allows the battery bank voltage to reach absorption levels (when PV harvest is adequate), the state of health of the battery is improved.

Peak Load Shaving

Many utilities impose a surcharge on their customers based on the peak load used by a facility. To reduce utility peak demand charges, the inverter can be configured (using the Load Shave Amps setting) to limit the maximum draw the AC loads place on the utility. The inverter can be programmed to provide power

Grid Support Settings

975-0385-01-01 3–19

above a specified level, eliminating the surcharge. When the utility current draw reaches the maximum level, the inverter assists by providing power from the batteries to the loads.

For Peak Load Shaving to be effective, all loads must be connected to the inverter. For large loads, multiple (or stacked) inverters may be required.

To further ensure the batteries are able to supplement the power requirements of the connected load, an additional source of power (solar, wind or hydroelectric) is recommended.

Peak Load Shaving can also be used in addition to the time-of-use metering.

Time-of-Use Metering

Utilities use time-of-use metering to determine utility charges during peak usage hours and to impose a surcharge. The XW Inverter/Charger can be configured (using the Load Shave Start, Load Shave Stop and Charger Block settings) to overcome these peak charges by using utility power to charge the battery bank during the inexpensive energy hours and consuming the battery energy during expensive energy hours.

For example, if Charger Block is set between 9:00 AM and 10:00 PM and Load Shave is set between 6:00 PM and 9:00 PM, charging on AC1 stops at 9:00 AM and continues to pass utility AC through to the loads. If charging is required during the charger block period, and AC Priority is set to AC2, the XW Inverter/ Charger can use any AC source connected to AC2. Loads will transfer to the AC source on AC2 as well. The inverter connects to the utility grid at 6:00 PM and supports loads using the batteries. The inverter continues to run until 9:00 PM. The XW Inverter/Charger then stops supporting the utility grid and passes utility AC through to the loads. At 10:00 PM utility AC begins maintaining the batteries based on the battery charger settings.

The above example allows an external renewable energy source to be utilized as a primary charging source during a desired time window. The charger (using utility AC connected to AC1) can then be used to supplement the battery charging when the rates utility rates are low.

When using the system for time-of-use metering, the system should be designed with a battery capacity large enough to support loads during the entire peak rate period without reaching the Low Battery Cut Out setting.

T o further ensure the batteries are able to support the loads, an additional source of power (solar, wind or hydroelectric) is recommended. Depending upon the capacity of the system, certain heavy loads should only be run during non-peak periods.

Note: If the batteries reach their Low Battery Cut Out voltage, the XW Inverter/

Charger automatically reconnects to the utility grid to maintain the connected load.

Configuration

3–20 975-0385-01-01

Generator Support Settings

Generator support allows power to be automatically drawn from the batteries to assist an AC generator to support heavy loads (loads that exceed the available current from the generator).

Generators have a limited output current and it is possible to reach this limit when operating heavy loads. The XW Inverter/Charger is designed to assist the generator when heavy current demands load down the generator by supplying additional power from the batteries.

In addition, the battery charger can back off its charging current to the batteries so the combined load of the charger and load support does not exceed the capacity of the generator or trip its output breakers or fuses.

For default settings, see “Gen Support Menu” on page B–5.

Note: Running and Start-up (Peak) currents are limited to the maximum current limits

of the inverter.

Configuration

3–22 975-0385-01-01

Trigger Source Descriptions

Low Batt Voltage Activates the Auxiliary Output when the battery voltage falls below the Low Batt Voltage setting for the trigger delay time. The Auxiliary Output turns off when the battery voltage rises above the Clear setting for the Clear Delay time. Use this setting if you want the auxiliary output to control a relay to disconnect loads from a battery that is nearly discharged, or to activate a low-battery-voltage alarm such as a buzzer or light.

High Batt Voltage Activates the Auxiliary Output when the battery voltage rises above the Hi Batt Voltage setting for the trigger delay time. The Auxiliary Output turns off when the battery voltage falls below the Clear setting for the Clear Delay time. This setting is useful for:

• Installations that have another external charging source such as a wind generator or hydro generator connected directly to the batteries. The XW Inverter/Charger Auxiliary Output can control a relay to disconnect the external charging source from the battery when the battery is in danger of being overcharged, or control a relay to turn on a diversion load.

• Activating a high-battery-voltage alarm such as a buzzer or light.

• Activating a vent fan to disperse hydrogen from the battery compartment when the batteries reach their gassing voltage.

Low Batt Temp Activates the Auxiliary Output when the battery temperature falls below the Low Batt Temp setting for the trigger delay time. The Auxiliary Output turns off when the battery temperature rises above the Clear setting for the Clear Delay time. Battery temperature is measured with a battery temperature sensor. Do not use this setting if a battery temperature sensor is not installed. With this setting, the auxiliary output can turn on an indicator alarm if the batteries are too cold. A battery with frozen electrolyte will not accept a charge.

High Batt Temp Activates the Auxiliary Output when the battery temperature rises above the Hi Batt Temp setting for the trigger delay time. The Auxiliary Output turns off when the battery temperature falls below the Clear setting for the Clear Delay time. Battery temperature is measured with a battery temperature sensor. Do not use this setting if a battery temperature sensor is not installed. With this setting, the auxiliary output can turn on a fan to cool the battery compartment.

Fault Activates the Auxiliary Output when a fault occurs. The Auxiliary Output clears when the fault is cleared.

Connections Menu

The Connections menu contains additional settings to allow the XW Inverter/ Charger to function as part of a multi-unit networked system.

Setting the connections for a Xanbus-enabled device provides a way of identifying non-network connections for Xanbus-enabled devices (see Figure 3-8) and enhancing networked power system managem e nt. When connections are set, devices of different types can detect that they share, for example, a common DC input source, or a common grid or generator source.

In multi-unit networked systems, inverter/chargers can be stacked to produce increased charge current. To achieve this functionality, the devices must be configured to the same DC connection, such as House Battery Bank 1. The inverter/chargers will collaborate on battery charging by listening to other units on this shared DC connection.

For default settings, see “Connections Menu” on page B–6.

Important:

When configuring multiple networked XW Inverter/Chargers with the System Control Panel, DC connections must be set to the same battery bank. If one of the units is set with a different DC connection, a system configuration fault (F66) occurs.

Although the XW Power System does support multiple XW Inverter/Chargers connected to multiple battery banks, such configurations cannot be set using the System Control Panel. A special configuration application provided by Xantrex is required. To configure such a system, contact your installer or Xantrex.

AC1 and AC2 connections can be set to “None” if operating without a connection to a specific power source. Only stand-alone devices (in a system that includes only the device and a System Control Panel) may be configured this way. Note that this is not a necessary configuration step as the system will still operate with the default settings. Using “None” where no AC source is used only serves as a label in this case and does not modify the behavior of a unit.
