Installation preparation

1. Prepare equipment and tools for installation
2. Check if the switch of the batteries unit is in the “OFF”state to ensure no live operation.

Electrical installation
Before connecting the power cables, using multimeter 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 multimeter 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 ofthe circuit breaker requires

BL3.6 Batteries Connecting Illustration
The accessory 3AWG wire of BL3.6 can support current of 1 A at most, so, when the inverter is parallel connected, and the output power of the inverter exceeds 5KW, additional main wire may be needed to realize the function of the whole system. 3.3.2 Take the inverter output power of 10KW, 15 15 KW, and 20KW as an example:

1. When two 5KW inverters are combined in parallel, the total output of the batteries will be 10KW, so the main wire will take 200A current at most. If the accessories, 4AWG or 6AWG wire is used to delivered 200A current, there will be serious heating and even the risk of component failure. Therefore, it is suggested to use design the main wire as designed in the schematics. The current capacity of the main wire should not exceed 200A，and the batteries and the main wire should be connected point-to-point. The two inverters communicate with the host batteries 1# through the Hub, as the schematic shows
2. The wiring of 15KW and 20KW output power of the inverter are similar with 10KW.
   Note : the red wire represents the main line of positive electrode, the positive electrode of a single batteries (purple wire) should be connected directly to the main wire; and the black wire represents the main wire of negative electrode, the negative electrode of a single batteries should be connected directly to the main wire

Two Inverters in Parallel

Three Inverters in Parallel

Use, maintenance and troubleshooting

Batteries system usage and operation instructions
After completing the electrical installation, follow these steps to start the batteries system. Refer to the description of the DIP switch of 2.3.1 to prepare the batteries module before starting up, then press the ON/OFF button to the ON position. After the indicator self-test, the RUN indicator will light and the SOC indicator will be on (100% SOC status in the Figure4-1).

Note:

1. After pressing the power button, if the batteries status indicator on the front panel continues to be red, please refer to the “4.2 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 42V, 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 42V, 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
