INTRODUCTION

This owner’s manual describes the Freedom Marine Series Inverter/Chargers from Xantrex. These units perform four distinct functions:

1.DC to AC power inverting.

2.Automatic transfer switching between inverter power and incoming AC power.

3.Automatic three-stage battery charging plus manual battery equalizing.

4.Multiple battery bank charging.

• The inverter provides regulated 120 volt AC power at a crystal controlled frequency from a deep cycle battery bank and is rated at:

Freedom 10

1000 watts

Freedom 15

1500 watts

Freedom 20

2000 watts

Freedom 25

2500 watts

Freedom 30

3000 watts

The output is a modified sine wave and is compatible with most appliances, tools and other 120 VAC equipment. (Note: Certain laser printers, breadmakers, digital clocks and small battery chargers may not operate on modfied sine wave.) The idle mode reduces battery power consumption when AC loads are

removed from the inverter output. High efficiency ensures the longest possible battery life between charges. All models are designed to deliver surge current for starting loads larger than the continuous rating of the inverter.

• The internal transfer switch allows the Freedom Inverter/Charger to be connected to an external AC source and transfer the source power through the unit directly to the loads. When the external AC power source is disconnected, the transfer switch allows automatic switching of the loads back to the inverter.

The Freedom Inverter/Charger operates as a self-contained backup power system— just add batteries.

• Freedom battery chargers with temperature sensitive charging (TSC) are electronically controlled. The primary charge output current is rated at 12 volts:

Freedom 10

50

amps DC

Freedom 15

75

amps DC

Freedom 20

100 amps DC

Freedom 25

130 amps DC

Freedom 30

140 amps DC

They are designed to rapidly and optimally charge wet cell, gel cell, or Absorbed Glass Mat (AGM)** deep-cycle batteries. Battery charging is automatically accomplished in three stages: Bulk Charge, Acceptance Charge and Float Charge. In most cases, no attention or maintenance is required.

When using a Freedom or LINK remote control panel, a manually engaged Equalize Charge cycle is possible.

**Battery type selection is set on the front of the unit or with an optional remote (Remote Control Panel or Link Instrument).

INTRODUCTION

Multiple Battery Bank Charging

Multiple battery bank charging is provided through additional output from the built-in echocharge. The echo-charge is used to charge start or auxiliary batteries. This Digital echocharge is current limited to 15 amps and follows the three-stage charge curve of the inverter/charger and battery setting of the house battery bank. The number of active echo-charge outputs depends of the model of the inverter/charger.

THINGS YOU SHOULD KNOW

Circuit Breaker Protection

The Freedom Inverter/Charger is supplemental circuit breaker protected. The INVERT/CHARGE breaker on the front of the unit protects against sustained inverter/ charger over-current conditions.

This supplemental circuit breaker protects the output of the unit when operating in “Invert Mode” and protects the internal battery charger circuits when operating in “Charge Mode.” When an over-current condition occurs, the circuit breaker is reset by pushing the button back in after the fault is removed. This circuit breaker is not suitable for branch circuit protection. To comply with NEC, additional branch circuit rated breakers may be required between the output of the unit and the load.

Freedom 25 and 30 have two outputs. Both outputs are protected by the supplemental circuit breaker when operating in “Invert Mode.” During transfer/charge operation, the outputs are protected by the circuit breakers feeding the two inputs to the unit.

Thermostat Controlled Cooling

Freedom Inverter/Chargers are equipped with a thermostatically controlled fan that cools the unit so it can operate continually at its rated output.

Inverter Idle Circuit

The idle circuit reduces battery power consumption when no AC load is present. Response from idle is instantaneous. When using a Freedom or Link remote control panel the idle threshold is adjustable. The unit does not produce 120 volts when in idle. An idle pulse is sent out approximately twice a second to see if a load is present. To bring the unit out of the idle condition, apply a load larger than the idle set point.

Low and High Battery Shutdown

When in inverter mode, if the battery voltage drops to 10.0 volts, the inverter will automatically shut off. Charge the batteries to 13.5 volts to automatically resume operation.

Voltage shutdown also occurs for a high battery condition at 15.5 volts. Operation will resume automatically when the battery voltage drops below 15.5 volts. Check all DC sources on the system for the reason for the excessive voltage.

Power Sharing

When connected to an external AC source the battery charger and transfer functions are engaged. A unique Power Sharing feature automatically reduces the AC power consumption of the battery charger when the loads threaten to trip the incoming circuit breaker.

Freedom 25 and 30 have two AC inputs. The battery charger is supplied AC from AC input #1. These models will reduce the current available to the charger when the demand for current to the load on AC output #1 reaches the factory default setting. AC input #2 is a direct transfer to AC output #2 and has no power sharing control.

6

THINGS YOU SHOULD KNOW

The Power Sharing set point of each unit has a factory default setting. This can be changed when using the Freedom or Link remote control panel. Refer to the Freedom Remote Control Panel or Link manual for information on Power Sharing setting and adjustment.

Temperature Sensitive Charging (TSC)

When the supplied battery temperature sensor is connected to the unit and the batteries, the charge voltage is controlled based on battery temperature. The charger adjusts the charge voltage to the best level insuring safe charging for selected battery type. Charge voltage regulation optimizes the battery life cycle.

Electronic Protection

Fast-acting electronic circuits protect the inverter from overloads and short circuits. Other protection includes a low and high battery voltage cutoff and automatic shutdown if an over temperature condition occurs. When the fault condition is corrected, the unit will automatically reset. For example: remove overload, charge batteries or allow to cool.

OPERATION

The Freedom Inverter/Charger provides 120 volt AC power from auxiliary DC batteries, automatic battery charging and automatic AC transfer switching between an external AC source and inverter mode AC output.

The Freedom Inverter/Charger may be operated with or without a remote control panel or Link instrument.

When operating the inverter/charger without a Freedom or Link remote control panel:

Front Panel Controls and Indicators

INVERT MODE

The INVERT push-button switch is located on the front of the unit.

• To turn the inverter ON, press and hold the INVERT switch until the INVERT LED is solid green. The unit is now inverting. Press the INVERT switch again to turn the inverter OFF. Note: The charge LED will be blinking slowly indicating Charger ready status but external AC power is not connected.

CHARGE MODE

The CHARGE push-button switch is located on the front of the unit.

When external AC is applied to the AC input of the unit, the charger automatically turns ON. The CHARGE LED will be solid green. The unit is now charging. Press the CHARGE switch again to turn the charger OFF. The charger defaults to ON when operating without a remote or with the Freedom Remote Control Panel. Refer to the Link manual when using a Link remote control panel.

Operation Status

INVERT - Green LED

When the LED is solid green, the unit is in invert mode. This occurs by pressing the INVERT switch.

When the LED is blinking slowly (1 time per second), the inverter is in standby with AC power applied and the transfer switch engaged

When the LED is OFF, the inverter is

OFF.

CHARGE - Green LED

When the LED is solid green, the unit is in the charge mode and external AC power is being supplied.

When the LED is blinking slowly, (1 time per second) the charger is ready, but external AC power is not available.

When the LED is OFF, the charger has been manually turned OFF. This can only be accomplished while AC power is being supplied since the charger will automatically restart each time AC power is applied.

Freedom Marine 20

OPERATION

NOTE: When AC power is available, the default setting for the charger is ON. If the unit was manually turned OFF and AC power is interrupted and becomes available again, the charger will return to ON.

LOW BATTERY - Red LED

When the LED is OFF the battery voltage is normal, between 10.5 and 15.0 volts DC.

When the LED is solid red, it indicates a battery warning condition, the battery voltage is below 10.5 volts DC or above 15.0 volts DC.

When the LED is blinking slowly, (once per second), a battery shutdown has occurred. The voltage is either below 10.0 volts DC or above 15.5 volts DC.

When the LED is blinking rapidly (five times per second), a potential problem in the DC system has been detected. Check your batteries, battery cables and DC loads.

OVER-TEMP/OVERLOAD - Red LED

When the LED is Off operation is normal.

When the LED is red, there is an overtemp or overload condition. Check for excessive loads or short circuit on the output of the inverter. Correct the condition and restart by pushing the INVERT switch.

When the LED is blinking slowly (once per second), an over-current condition or a short circuit has occurred. The system has shut OFF and will not automatically restart. Correct the fault condition and manually restart the system by pushing the INVERT switch.

LOW BATTERY & OVER-TEMP/OVERLOAD

- Red LEDs

When both LEDs are blinking, an AC backfeed was detected. A backfeed occurs

when AC power from an external source is connected to the output of the inverter. Inspect wiring for a possible input/output wiring error. This condition must be corrected before further operation. A backfeed will damage the unit and void the warranty.

Battery Type Selection

• Battery type setup. To enter the battery type select mode, press and hold the INVERT switch for five seconds. The status LEDs will change from indicating status information to OFF. Press the CHARGE switch once. One of the four LEDs will blink rapidly, indicating the existing battery type selection.

Press the CHARGE switch again to change the battery type. Continue to press until the desired battery type is selected. If the CHARGE switch is not pressed for five seconds, the unit will return to normal operation and the battery type selection will have been made. Refer to page 20 for additional information on battery type settings.

When the 12 volt input to the unit is disconnected, the battery type setting is stored in non-volatile memory. When the unit is reconnected, the battery type selection conveniently returns to the previous setting.

If installed with the Freedom or Link remote control panel, the unit will be set up and controlled from the remote. Refer to the remote manual for more information.

9

OPERATION

When a Freedom or Link remote control panel is connected to the unit, the switch on the unit or on the remote may be used to turn the unit ON/OFF. If the unit is turned ON using the front panel switch and then turned OFF using a Remote or Link, the unit will not be completely OFF. If the unit will not be used for an extended period of time, turn the unit completely OFF. The unit is completely OFF when the LED display on the unit is OFF.

TSC (Temperature Sensitive Charging)

This provides for the connection of a sensor to measure battery temperature for compensated charging. If no sensor is connected the charge voltage levels are set to defaults based on battery type.

echo-charge

The echo-charge feature is incorporated in the Freedom Marine Inverter/Charger to enable multiple battery bank charging of the start or auxiliary battery. Freedom 10, 15, 20 have one active echo-charge output. Freedom 25, 30 have two active outputs.

The echo-charge automatically switches On/Off, charging an auxiliary or start battery without affecting the main house battery bank. The maximum charge current is 15 amps at

14.4volts.

The echo-charge is a voltage follower, fol-

lowing the three-stage charge modes of the Freedom Marine Charger. The echo-charge senses if the start battery needs charging and diverts a portion of the charging current (up to 15 amps) to the start battery. This method pro-

tects the auxiliary battery from overcharging and ensures a long life for the battery.

NOTE: The charger will always follow the house battery setting, even if you mix the type of batteries in your house and start battery bank. If the house battery bank is either GEL or AGM and the start or auxiliary battery is wet/ flooded, the charger will follow the GEL or AGM voltage setting.

The echo-charge will turn ON any time the house battery is above 13 volts, regardless of the charging source.

BATTERIES

BATTERY TYPES

Use only deep-cycle batteries with your Freedom Inverter/Charger. These fall into three broad categories: wet cell, gel cell and Advanced AGM (Absorbed Glass Mat) batteries.

Wet Cell Batteries

True deep-cycle wet cell batteries are characterized by relatively thick internal plates that are alloyed with antimony.

Common 12 volt marine/RV deep-cycle batteries are acceptable. Golf cart batteries perform well and may have a longer life. These 6 volt batteries must be used in series connected pairs. High quality deep-cycle batteries offer good performance and are available in a wide variety of sizes.

Wet cell batteries will give off gas as a natural result of charging and will experience some water loss. It is very important that the electrolyte level be checked frequently and topped off with distilled water when necessary. Follow the battery manufacturer’s recommendations for maintenance.

Never allow the top of the battery plates to be exposed to air, as contamination of the cell will result. Keep the tops of batteries clean.

Always provide adequate ventilation for the battery storage compartment.

Do not use ordinary car batteries or engine starting batteries with your inverter/ charger. Beware of any battery that is rated only in Cold Cranking Amps (CCA). This is a rating which applies only to engine starting batteries. In general, most wet cell batteries that are described as hybrid type batteries, suitable for either engine starting or deep-cycle applications, are a compromise and will have limited life if deeply discharged.

12

BATTERIES

Beware of so-called maintenance-free wet cell batteries. These batteries have calcium alloyed with the lead liquid. They are sealed and water cannot be added. Do not confuse them with true gel cell or AGM batteries—they will not hold up well to deep discharging and repeated cycling.

Gel Cell Batteries

Gel cell batteries are lead-acid batteries similar in many ways to the common wet cell battery, but differences in the chemistry and construction provide some unique features.

No Maintenance

Low Self-Discharge Rate

Low Internal Resistance

Even though gel cells are sealed batteries, the battery compartment should still be ventilated.

Advanced AGM (Absorbed Glass Mat) Batteries

This battery is lead acid but maintenance free. They hold the liquid electrolyte in a sponge-like material. The performance is similar to gel cell batteries. The charge parameters are similar to wet cell batteries.

Battery Selection

The most important feature to consider in making your battery selection is to select true deep cycle batteries rated in amp hours (Ah) and sized to match your power requirements.

BATTERY INTERCONNECTION

In most cases, you will be using a bank of two or more batteries with your inverter/charger. You may connect batteries together in two configurations—series and parallel— depending on their voltage.

Series Configuration

Connecting two batteries in series will double the voltage of the battery bank. For instance, two 6 volt batteries connected in series will produce 12 volts. The amp-hour capacity of the battery bank will be the same as each individual battery. Example, two 6 volt 220 amp-hour batteries in series will produce one 12 volt 220 amp-hour battery bank.

Only similar batteries should be connected together in one bank. Do not connect old and new batteries together or wet and gel cell batteries together. In the above drawing, the load is connected to the positive terminal of the first battery and the negative terminal of the last battery. This practice helps to balance the battery bank and is called cross-connecting the battery bank.

Note: It is not advisable to connect batteries of different case sizes or amp-hour ratings in the same battery bank.

Always use properly sized wire and terminals for your interconnecting battery cables. For size information refer to NEC requirements or contact your local electrician.

BATTERY BANK RATINGS AND SIZING

Deep-cycle batteries are usually rated in amp hours. The amp-hour rating is based on a 20-hour discharge rate, therefore, a 100 amp-hour battery can deliver 5 amps for 20 hours. If the discharge rate is greater than 5 amps, the available amp hours are decreased. For example, if the load is increased to 100 amps, only about 45 amp hours will be available at this rate of discharge.

Deep-cycle batteries can be discharged about 80% of capacity before damage occurs. Shallow cycling will result in much longer battery life. Calculating a battery bank size based on 50% discharge cycling is generally considered to be a good compromise between long battery life and size.
