Supports Up to 12 Units in Parallel

• The parallel operation function allows for easy expansion of the solar panel configuration and energy storage capacity limits, thus increasing the scale of energy storage. For detailed parallel operation guidelines, refer to Section 7.

Adaptive Boost Charging

• During the initial charging phase, adaptive boost charging monitors battery response and automatically determines the duration of the boost stage for each independent charging cycle, ensuring that the battery is fully charged at any discharge level or capacity while avoiding overcharging during the boost charging stage (extends battery life).

Durable and Secure

• a. Photovoltaic input overcurrent
• b. Photovoltaic array short circuit
• c. Reversed photovoltaic polarity
• d. Overvoltage protection for batteries
• e. Overdischarge protection for batteries

Choosing the Installation Location

Before installation, several aspects should be considered to determine or provide a suitable and safe installation location.

Wiring Precautions

1. Installation and wiring work should be carried out by a certified electrician.
2. Wiring should follow the sequence of Battery > PV Input > Load.
3. To avoid short-circuits and polarity reversal, pay attention to connecting the positive (+) cable to the device’s positive (+) terminal and the negative (-) cable to the device’s negative (-) terminal.
4. Loose and/or incomplete connections can lead to cable or terminal overheating. Therefore, tighten all cables to minimize transition resistance, using cable sizes appropriate for the specific circuit’s current rating.
5. Do not connect the inverter to the load terminal of the controller, as doing so may result in irreversible damage to the equipment. If it is necessary to connect the inverter, please follow the battery connection steps outlined in Section 2.4, as indicated in the wiring diagram.

Installation and Wiring Guidelines

Please refer to the following steps to complete the installation and wiring of the controller. Alternatively, scan the QR code on the right to access the operating guide.

NOTE

• For parallel connection wiring, please refer to Chapter 7.
• Step 1. Install the controller vertically with its ports facing downward, securing it to the wall **** through the four mounting holes using screws.
• For ease of installation, it is recommended to use two upper screws for the initial “hanging” of the device, followed by the addition of two lower screws, and then fully tighten all four screws.
• Step 2. Battery Wiring: Connect the battery to the controller using cables.

Attention:

• Do not connect the inverter to the load terminal of the controller; otherwise, it may cause irreversible damage to the equipment. If it is necessary to connect the inverter, please refer to the diagram below.

NOTE

• All wiring work must be carried out by professionals.
• For safe operation and proper application, circuit breakers of the appropriate specifications must be installed on the cables connected to the controller, and ensure that the connections are tight.
• Ensure that all circuit breakers are in the off position before completing all wiring.
• Connect the positive cable terminal to the positive terminal port, and the negative cable terminal to the negative terminal port.
• The above notes also apply to the PV ports and DC output ports.
• Step 3. PV Wiring: Connect the photovoltaic array to the controller using cables.
• Step 4. DC Output Wiring: Connect the load to the controller using cables.
• Step 5. Temperature Probe Connection: Connect the temperature probe wire to the controller and securely fix the probe end to the battery using insulation tape.
• Step 6. Pre-Startup Check: Refer to the wiring diagram below. If all connections are accurate, and all wiring is securely connected, close the circuit breakers in the order of Battery, PV Input, and Load terminals.

WARNING: Risk of Electric Shock!

• Before wiring, ensure that all power sources are turned off and follow the relevant inspection and operation procedures.

Setting Guidelines

D00 Load Operation Mode Setting

Configure the mode and duration for enabling the load output.

1. 00H: Light control mode. (Activates DC output when sufficient solar energy is available)
2. 24H (Default): Immediate load activation.
3. 01H~23H: Adjust the duration for load activation.

D01 Float Charge Voltage Setting

• After the boost charge phase, the controller will reduce the battery voltage by decreasing the charging current and maintaining the battery at the float charge voltage setting value to keep the battery in a fully charged state.
• Please adjust this setting based on the charging parameters of the connected batteries.

D02 Boost Charge Voltage Setting

• During the boost charge phase, the battery will be charged at a constant preset voltage value. Please set this value according to the specific charging parameters of your batteries.

D03 Low Voltage Disconnect Setting

• When the battery voltage falls below the value set in D03, the controller will stop discharging the battery to prevent over-discharging.

D04 Voltage Calibration Setting

• This setting allows you to calibrate the displayed battery voltage when there is a difference between the controller’s detected voltage and the voltage measured with a multimeter.
• Please note that using excessively long or thin cables can affect the controller’s ability to accurately read the battery voltage.

D05 Parallel Communication Code Setting

• NOTICE This program requires no configuration if you are not operating in parallel mode.
• After completing the parallel wiring, you can use the D05 setting program to define the master and slave controllers.
• The controller with the lowest communication code value will be the master. In parallel operation, if the master encounters an issue, the system will automatically select the controller with the next code value as the new master.
• For example, if the No. 01 master fails, the system will designate No. 02 as the new master.

Assuming six controllers are operating in parallel:

Protection

Protection Function

current to the maximum battery current rating. Consequently, an overcurrent from the photovoltaic array input will not allow it to operate at peak power.
Photovoltaic Array Short Circuit| When a short circuit occurs in the photovoltaic array, the the controller will stop charging, and operation can be restored by eliminating the short circuit fault.
Photovoltaic Polarity Reversal| If the photovoltaic input wiring polarity is reversed, the controller will not operate, and it will not damage the controller. After proper reconnection, the controller will operate normally.
Battery Overvoltage| When the battery voltage exceeds 15.5/31.0/46.5/62.0V, the controller will stop charging to protect the battery from overcharging damage. Please note that stopping the charging means the charging current is very low.
Battery Over-discharge| When the battery voltage drops to the low- voltage disconnect setpoint, the controller will stop discharging to protect the battery from over-discharge damage.
**** Over-temperature Protection| When the battery voltage drops to the low-voltage disconnect setpoint, the controller will stop discharging to protect the battery from over-discharge damage.

Maintenance

We recommend conducting the following checks and maintenance at least twice a year to ensure optimal performance:

1. Ensure the controller is securely mounted in a clean and dry environment.
2. Ensure proper airflow around the controller and clean any dust or debris from the heat sinks.
3. Inspect all exposed wires for insulation damage, such as severe sun exposure, friction wear, dryness, and insect or rodent damage. Repair or replace any damaged wires as necessary.
4. Tighten all terminals and check for loose, broken, or burnt cable connections.
5. Confirm that all system components are properly grounded.
6. Ensure all terminals are free from corrosion, insulation damage, high temperatures, or signs of burning/discoloration, and tighten terminal screws.
7. Check for dirt, nesting insects, and corrosion. If present, clean promptly.

WARNING: Risk of electric shock!

Before performing the above operations, ensure that all power sources are turned off and then follow the relevant check and operation guidelines.
