Electrical interface check

Devices that connected directly to the batteries can be user equipments, power supplies,and other power supplies.

• Please check if the user’s PV power generation equipment, power supplier or other power supply equipment has a DC output interface, and the voltage meet the requirements of the inverter.
• And check the maximum discharge current capability of the DC power interface of the user’s photovoltaic power generation equipment, power supply or other power supply equipment should be greater than the maximum charging current of the products.

Electrical installation

Before connecting the power cables, using multi meter to measure cable continuity， short circuit, confirm positive and negative, and accurately mark the cable labels.

Measuring methods:

• Cable availability: select the buzzer and use the probe to measure the ends of the same color cable. If the buzzer calls, it means the cable is available.
• Short circuit judgment: choose multi meter resistor file, probe the same end of positive and negative pole, if the resistor shows infinity, means that the cable is available.
• After visual testing of power line is connected well, the positive and negative poles of the batteries shall be connected respectively to the positive and negative poles of the opposite terminal.

It is better to add a circuit breaker between the inverter and the batteries system. The selection of the circuit breaker requires:

Use, maintenance and troubleshooting

Batteries system usage and operation instructions

After completing the electrical installation, follow these steps to start the batteries system

1. Refer to 1.3, Press the self-locking switch to ON position, The display screen and indicator will light up
2. After the indicator self-test, the RUN indicator will light and the SOC indicator will be on.

Note:

1. After pressing the power button, if the batteries status indicator on the front panel continues to be red, please refer to the “3.5 Alarm description and processing “.If the failure cannot be eliminated, please contact the dealer timely.
2. Use a voltmeter to measure whether the voltage of the circuit breaker batteries access terminal is greater than 43V, and check whether the voltage polarity is consistent with the inverter input polarity. If the circuit breaker batteries input terminal has a voltage output and is greater than 43V, then the batteries has started normal work.
3. After confirming that the batteries output voltage and polarity are correct, turn on the inverter, close the circuit breaker.
4. Check if the indicator of the inverter and batteries connection (communication indicator and batteries access status indicator)is normal. if it is normal, successfully complete the connection between the batteries and the inverter. If the indicator light is abnormal, please refer to the inverter manual for the cause or contact the dealer.

• Self- Shutdown
  • When there are no external loads and power supply and no external communication for over 24 hours , the device will dormant standby automatically.

Key description and buzzer action description

Key description

• When the BMS is in sleep state, press the button (3~6S) and release it, the protection board will be activated, and the LED indicators will light up sequentially for 0.5 seconds from “RUN”.
• When the BMS is active, press the button (3~6S) and then release it, the protection board will be dormant, and the LED indicators will light up for 0.5 seconds from the lowest battery light.
• When the BMS is active, press the button (6~10S) and release it, the protection board will be reset, and all LED lights will light up simultaneously for 1.5 seconds.
• After the BMS is reset, it still retains the parameters and functions set by the host computer. If it is necessary to restore the initial parameters, it can be realized through the “restore default value” of the host computer. However, the relevant operating records and stored data remain unchanged (such as power, cycle times, protection records, etc.)

buzzer action description

• When there is a fault, it will beep 0.25S every 1S;
• During protection, it beeps for 0.25S every 2S (except for over voltage protection);
• When alarming, beep 0.25S every 3S (except for over voltage alarm);

The buzzer function can be enabled or disabled through the host computer, and the factory default is disabled.

Communication Description

RS232

The BMS can communicate with the host computer through the RS232 interface, so that various information of the battery can be monitored through the host computer, including battery voltage,Current, temperature, status and battery production information, etc., the default baud rate is 9600bps.

CAN

• CAN communication, the default communication rate is 500K

RS485

• With dual RS485 interfaces, you can view the information of PACK, and the default baud rate is 9600bps.
• If you need to communicate with the monitoring device through RS485, the monitoring device acts as the host and polls the data according to the address

DIP switch setting

• When the PACKS are used in parallel, different PACKS can be distinguished by setting the address through the DIP switch on the BMS.
• It is necessary to avoid setting the same address. For the definition of the BMS DIP switch, refer to the table below：

Form 4.4
