2. Installation Instructions

2.1 General Installation Notes

 Please read the entire installation instructions to get familiar with the installation

steps before installation.

 Be very careful when installing the batteries, especially flooded lead-acid battery.

Please wear eye protection, and have fresh water available to wash and clean any contact with battery acid.

 Keep the battery away from any metal objects, which may cause short circuit of the

battery.

 Explosive battery gases may come out from the battery during charging, so make

sure ventilation condition is good.

 Ventilation is highly recommended if mounted in an enclosure. Never install the

controller in a sealed enclosure with flooded batteries! Battery fumes from vented batteries will corrode and destroy the controller circuits.

 Loose power connections and corroded wires may result in high heat that can melt

wire insulation, burn surrounding materials, or even cause fire. Ensure tight connections and use cable clamps to secure cables and prevent them from swaying in mobile applications.

 The controller can work with lead-acid battery and lithium battery within its control

scope.

 Battery connection may be wired to one battery or a bank of batteries. The following

instructions refer to a singular battery, but it is implied that the battery connection can be made to either one battery or a group of batteries in a battery bank.

 Multiple same models of controllers can be installed in parallel on the same battery

bank to achieve higher charging current. Each controller must have its own solar module(s).

 Select the system cables according to 5A/mm2 or less current density in accordance

with Article 690 of the National Electrical Code, NFPA 70.

2.2 PV Array Requirements

(1) Serial connection (string) of PV modules

As the core component of solar system, controller could be suitable for various types of PV modules and maximize converting solar energy into electrical energy. According to the open circuit voltage (Voc) and the maximum power point voltage (V

Mpp

) of the MPPT controller, the series number of different types PV modules can be calculated. The below table is for reference only.

(2) Maximum PV array power

The MPPT controller has the function of charging current/power-limiting, that is, during the charging process, when the charging current or power exceeds the rated charging current or power, the controller will automatically limit the charging current or power to the rated range, which can effectively protect the charging parts of controller, and prevent damages to the controller due to the connection of some over-specification PV modules. The actual operation of PV array is as follows:

Condition 1:

Actual charging power of PV array ≤ Rated charging power of controller

Condition 2:

Actual charging current of PV array ≤ Rated charging current of controller When the controller operates under “Condition 1”or“Condition 2”, it will carry out the

charging as per the actual current or power; at this time, the controller can work at the maximum power point of PV array.

WARNING: When the power of PV is not greater than the rated charging power, but the maximum open-circuit voltage of PV array is more than 60V(XTRA**06N)/100V(XTRA**10N)/150V(XTRA**15N) (at the lowest environmental temperature), the controller may be damaged.

Condition 3:

Actual charging power of PV array＞Rated charging power of controller

Condition 4:

Actual charging current of PV array＞Rated charging current of controller

When the controller operates under “Condition 3”or“Condition 4”，it will carry out the charging as per the rated current or power.

WARNING: When the power of PV module is greater than the rated charging power, and the maximum open-circuit voltage of PV array is more than 60V(XTRA**06N)/100V(XTRA**10N)/150V(XTRA**15N) (at the lowest environmental temperature), the controller may be damaged.

According to “Peak Sun Hours diagram”, if the power of PV array exceeds the rated charging power of controller, then the charging time as per the rated power will be prolonged, so that more energy can be obtained for charging the battery. However, in the practical application, the maximum power of PV array shall be not greater than 1.5 x the rated charging power of controller. If the maximum power of PV array exceeds the rated charging power of controller too much, it will not only cause the waste of PV modules, but also increase the open-circuit voltage of PV array due to the influence of environmental temperature, which may make the probability of damage to the controller rise. Therefore, it is very important to configure the system reasonably. For the recommended maximum power of PV array for this controller, please refer to the table below:

2.3 Wire Size

The wiring and installation methods must conform to all national and local electrical code requirements.

 PV Wire Size Since PV array output can vary due to the PV module size, connection method or

sunlight angle, the minimum wire size can be calculated by the Isc＊ of PV array. Please refer to the value of Isc in the PV module specification. When PV modules connect in series, the Isc is equal to a PV modules Isc. When PV modules connect in parallel, the Isc is equal to the sum of the PV modules’Isc. The Isc of the PV array

must not exceed the controller’s maximum PV input current. Please refer to the table as below:

NOTE: All PV modules in a given array are assumed to be identical. ＊Isc=short circuit current(amps) Voc=open circuit voltage.

CAUTION: The wire size is only for reference. If there is a long distance between the PV array and the controller or between the controller and the battery, larger wires can be used to reduce the voltage drop and improve

performance.

CAUTION: For the battery, the recommended wire will be selected according to the conditions that its terminals are not connected to any additional inverter.

2.4 Mounting

WARNING: Risk of explosion! Never install the controller in a sealed enclose

with flooded batteries! Do not install in a confined area where battery gas can accumulate.

WARNING: Risk of electric shock! When wiring the solar modules, the PV array can produce a high open circuit voltage, so turn off the breaker before wiring and be careful when wiring.

CAUTION：The controller requires at least 150mm of clearance above and below for proper air flow. Ventilation is highly recommended if mounted in an enclosure.

Installation Procedure:

Step 1: Determination of Installation Location and Heat-dissipation Space

Figure 2-1 Mounting

Determination of installation location: The controller shall be installed in a place with sufficient air flow through the radiators of the controller and a minimum clearance of 150 mm from the upper and lower edges of the controller to ensure natural thermal convection. Please see Figure 2-1: Mounting

CAUTION: If the controller is to be installed in an enclosed box, it is important to ensure reliable heat dissipation through the box.

Step 2：Connect the system in the order of ❶battery ❷ load ❸PV array in

accordance with Figure 2-2,”Schematic Wiring Diagram” and disconnect the system in the reverse order❸❷❶.

CAUTION: While wiring the controller do not close the circuit breaker or fuse and make sure that the leads of "+" and "-" poles are connected correctly.

CAUTION: A fuse which current is 1.25 to 2 times the rated current of the controller, must be installed on the battery side with a distance from the battery not greater than 150 mm.

CAUTION: If the controller is to be used in an area with frequent lightning strikes or unattended area, it must install an external surge arrester.

CAUTION: If an inverter is to be connected to the system, connect the inverter directly to the battery, not to the load side of the controller.

Step 3：Grounding

XTRA N series is a common-negative controller, where all the negative terminals of PV array, battery and load can be grounded simultaneously or any one of them will be

Figure 2-2 Schematic of wiring diagram

grounded. However, according to the practical application, all the negative terminals of PV array, battery and load can also be ungrounded, but the grounding terminal on its shell must be grounded, which may effectively shield the electromagnetic interference from the outside, and prevent some electric shock to human body due to the electrification of the shell.

CAUTION: For common-negative system, such as motorhome, it is recommended to use a common-negative controller; but if in the common-negative system, some common-positive equipment are used, and the positive electrode is grounded, the controller may be damaged.

Step 4：Connect accessories  Connect the remote temperature sensor cable

（Model:RT-MF58R47K3.81A）（Model:RTS300R47K3.81A）

Connect the remote temperature sensor cable to the interface ① and place the other end close to the battery.

CAUTION: If the remote temperature sensor is not connected to the controller,, the default setting for battery charging or discharging temperature is 25 °C without temperature compensation.

 Connect the accessories for RS485 communication

Refer to chaper4 “Control Parameters Setting”.

Step 5：Powered on the controller

Closing the battery fuse will switch on the controller. Then check the status of the battery indicator (the controller is operating normally when the indicator is lit in green). Close the fuse and circuit breaker of the load and PV array. Then the system will be operating in the preprogrammed mode.

CAUTION: If the controller is not operating properly or the battery indicator on the controller shows an abnormality, please refer to 5.2

“Troubleshooting”.

5. Protections, Troubleshooting and Maintenance

5.1 Protection

PV Over

Current/power

When the charging current or power of the PV array exceeds the controller’s rated current or power, it will be charge at the rated current or power.

NOTE: When the PV modules are in series, ensure that the open-circuit voltage of the PV array does not exceed the "maximum PV open-circuit voltage" rating. Otherwise the controller may be damaged.

PV Short Circuit

When not in PV charging state, the controller will not be damaged in case of a short-circuiting in the PV array.

PV Reverse Polarity

When the polarity of the PV array is reversed, the controller may not be damaged and can continue to operate normally after the polarity is corrected.

NOTE: If the PV array is reverse connected to the controller,1.5 times rated controller power(watts)from the PV array, will damage the controller.

Night Reverse Charging

Prevents the battery from discharging to the PV module at night.

Battery Reverse Polarity

Fully protected against battery reverse polarity; no damage will occur to the battery. Correct the miswire to resume normal operation.

NOTE: Limited to the characteristic of lithium battery, when the PV connection is correct and battery connection reversed, the controller will be damaged.

Battery Over Voltage

When the battery voltage reaches the over voltage disconnect voltage, it will automatically stop battery charging to prevent battery damage caused by over-charging.

Battery Over Discharge

When the battery voltage reaches the low voltage disconnect voltage, it will automatically stop battery discharging to prevent battery damage caused by over-discharging. (Any controller connected loads will be disconnected. Loads directly connected to the battery will not be affected and may continue to discharge the battery.)

Battery Overheating

The controller can detect the battery temperature through an external temperature sensor. The controller stops working when its

temperature exceeds 65 °C and restart to work when its temperature is below 55 °C.

Lithium Battery Low Temperature

When the temperature detected by the optional temperature sensor is lower than the Low Temperature Protection Threshold(LTPT), the controller will stop charging and discharging automatically. When the detected temperature is higher than the LTPT, the controller will be working automatically (The LTPT is 0 °C by default and can be set within the range of 10 ~ -40 °C).

Load Short Circuit

When the load is short circuited (The short circuit current is ≥ 4 times the rated controller load current), the controller will automatically cut off the output. If the load reconnects the output automatically five times (delay of 5s, 10s, 15s, 20s, 25s), it needs to be cleared by pressing the Load button, restarting the controller or switching from Night to the Day (nighttime > 3 hours).

Load Overload

When the load is overloading (The overload current is ≥ 1.05 times the rated load current), the controller will automatically cut off the output. If the load reconnects automatically five times (delay of 5s, 10s, 15s, 20s, 25s), it needs to be cleared by pressing the Load button restarting the controller, switching from Night to Day (nighttime > 3 hours).

Controller Overheating★

The controller is able to detect the temperature inside the battery. The controller stops working when its temperature exceeds 85 °C and restart to work when its temperature is below 75 °C.

TVS High Voltage Transients

The internal circuitry of the controller is designed with Transient Voltage Suppressors (TVS) which can only protect against high-voltage surge pulses with less energy. If the controller is to be used in an area with frequent lightning strikes, it is recommended to install an external surge arrester.

★When the internal temperature is 81℃, the reduce charging power mode which reduce the charging power of 5%,10%,20%,40% every increase 1 ℃ is turned on. If the internal temperature is greater than 85℃, the controller will stop charging. When

the temperature declines to be below 75 ºC, the controller will resume. For example XTRA4215N 24V system:

 Make sure no block on air-flow around the controller. Clear up any dirt and

fragments on heat sink.

 Check all the naked wires to make sure insulation is not damaged for sun

exposure, frictional wear, dryness, insects or rats etc. Repair or replace some wires if necessary.

 Tighten all the terminals. Inspect for loose, broken, or burnt wire connections.  Check and confirm that LED is consistent with required. Pay attention to any

troubleshooting or error indication .Take corrective action if necessary.

 Confirm that all the system components are ground connected tightly and

correctly.

 Confirm that all the terminals have no corrosion, insulation damaged, high

temperature or burnt/discolored sign, tighten terminal screws to the suggested torque.

 Clear up dirt, nesting insects and corrosion in time.  Check and confirm that lightning arrester is in good condition. Replace a new

one in time to avoid damaging of the controller and even other equipments.

WARNING：Risk of electric shock! Make sure that all the power is turned off before above operations, and then follow the corresponding inspections and operations.
