2 Installation
2.1 Attentions
Please read the instructions to familiarize yourself with the installation steps before installation. Be very careful when installing the batteries, especially flooded lead-acid batteries. 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 a short circuit of the battery. Explosive battery gases may come out from the battery during charging, so make sure the
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 produce high heat that can melt wire insulation, burn surrounding materials, or even cause a fire. Ensure tight connections, use cable clamps to secure cables, and prevent them from swaying in mobile applications. The controller can work with lead-acid and lithium batteries within its control scope. The battery connection may be wired to one battery or a bank of batteries. The following instructions refer to a singular battery. However, it is implied that the battery connection can be made to either one battery or a group of batteries in a battery bank. Multiple models of controllers can be installed in parallel on the same battery bank to achieve a higher charging current. Each controller must have its solar module(s). Select the system cables according to 5A/mm2 or less current density following Article 690 of the National Electrical Code, NFPA 70.
2.2 PV Array Requirements
Serial connection (string) of PV modules As the core component of the solar system, the controller could be suitable for various types of PV modules and maximize converting solar energy into electrical energy. According to the open-circuit

2.3 Wire Size

The wiring and installation methods must conform to national and local electrical code requirements.
PV Wire Size
The PV array output varies with the PV module size, connection method, and sunlight angle. The PV array’s short circuit current(ISC) can calculate the minimum PV wire size. Please refer to the value of Isc in the PV module specification. When PV modules are connected in series, the Isc equals a PV module Isc. When PV modules are connected in parallel, the Isc equals 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 below: NOTE: All PV modules in a given array are assumed to be identical.

CAUTION

The wire size is only for reference. Suppose there is a long distance between the PV array, the controller, and the battery. In that case, larger wires can be used to reduce the voltage drop and improve performance.

The recommended battery wire is selected when the battery 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.
Risk of electric shock! When wiring the solar modules, the PV array can produce a high open-circuit voltage, so disconnect the breaker before wiring and be careful.

CAUTION

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

Installation Procedure:

Figure 2-1 Mounting Step 1: Determination of the installation location and heat-dissipation space
The controller shall be installed in a place with sufficient airflow through the controller radiators and a minimum clearance of 150 mm from the upper and lower edges of the controller to ensure natural thermal convection. See Figure 2-1: Mounting

CAUTION

Suppose the controller is to be installed in an enclosed box. In that case, ensuring reliable heat dissipation through the box is important.

9

Figure 2-2 Schematic of wiring diagram Step 2Connect the system in the order of battery load PV array by Figure 2-2,” Schematic Wiring Diagram” and disconnect the system in the reverse order.

CAUTION

While wiring the controller, do not connect the circuit breaker or fast-acting fuse and ensure that the electrode polarity is correctly connected.
A fast-acting fuse whose 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.
Suppose the controller is to be used in an area with frequent lightning strikes or an unattended area. In that case, it must install an external surge arrester.
Suppose an inverter is to be connected to the system. In that case, you must connect the inverter directly to the battery, not to the load side of the controller.

Step 3Grounding XTRA N series are common-negative controllers; all the negative terminals can be grounded simultaneously, or anyone is grounded. However, according to the practical application, the negative terminals of the PV array, battery, and load can also be ungrounded. Still, the grounding terminal on the shell must be grounded. It effectively shields the electromagnetic interference from the outside and prevents some electric shock to the human body.

10

A common-negative controller for a common-negative system, such as the motorhome, is recommended. CAUTION The controller may be damaged if a common- positive controller is used and the positive electrode is grounded in the common-negative system. Step 4Connect accessories
Connect the remote temperature sensor cable

Temperature Sensor
Model:RT-MF58R47K3.81A

Remote Temperature Sensor
Cable (Optional) Model:RTS300R47K3.81A

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

CAUTION

Suppose the remote temperature sensor is not connected to the controller. In that case, the default battery charging or discharging temperature setting is 25 °C without temperature compensation.

Connect the accessories for RS485 communication

Refer to chaper4 “Control Parameters Setting.” Step 5Power on the controller

Connect the battery fast-acting fuse to power the controller. Then check the battery indicator’s status (the controller operates normally when the indicator is lit in green). Connect the fast-acting fuse and circuit breaker of the load and PV array. Then the system will be operating in 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 Others

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 charged at the rated current or power.
WARNING: When the PV’s charging current is higher than the rated current, the PV’s open-circuit voltage cannot be higher than the “maximum PV open-circuit voltage.” Otherwise, the controller may be damaged.

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

PV Short Circuit

WARNING: It is forbidden to short-circuit the PV array during charging. Otherwise, the controller may be damaged.

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.
CAUTION: The controller is damaged when the PV array is connected reversely to the controller, and the PV array’s actual operating power exceeds 1.5 times the rated charging power.

Night Reverse Charging Prevents the battery from discharging to the PV module at night.

Fully protected against reverse battery polarity; no damage will occur to the battery. Correct the miswire to resume normal
operation. Battery Reverse Polarity
WARNING: The controller, limited to the lithium battery characteristic, will be damaged when the PV connection
is correct and the battery connection is reversed.

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

33

battery damage caused by over-discharging. (Any 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 restarts 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 work automatically (The LTPT is 0 °C by default and can be set within 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. Suppose the load reconnects the output five times (delay of 5s, 10s, 15s, 20s, 25s). In that case, 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. Suppose the load reconnects five times (delay of 5s, 10s, 15s, 20s, 25s). In that case, it needs to be cleared by pressing the Load button restarting the controller, or switching from Night to Day (nighttime > 3 hours).

The controller can detect the temperature inside the battery. The controller stops working when its temperature exceeds Controller Overheating
85 °C and restarts 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. Suppose the controller is to be used in an area with frequent lightning strikes. In that case, it is recommended to install an external surge arrester.

When the internal temperature is 81, the reduced charging power mode is turned on. It reduces the charging power by 5%,10%,20%, and 40% with

every increase of 1. If the internal temperature exceeds 85, the controller will stop charging. When the temperature declines to be below 75 ºC, the

controller will resume.

5.3 Maintenance

The following inspections and maintenance tasks are recommended at least twice yearly for best performance.
Make sure the controller is firmly installed in a clean and dry ambient. Make sure no block on airflow around the controller. Clear up any dirt and fragments on the
heat sink. Check all the naked wires to ensure insulation is not damaged by 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 damage, 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 the lightning arrester is in good condition. Replace a new one in time
to avoid damaging the controller and other equipment.

WARNING

Risk of electric shock! Ensure all the power is turned off before the above operations, and then follow the corresponding inspections and operations.
