4.1 Battery system usage and operation instructions
After completing the electrical connection, please follow these steps to start the battery
system.
1. Refer to 2.3.2 for the definition of the DIP switch and prepare for the DIP before turning on the
system, and then turn the switch ON/OFF to ON.
After the battery indicator completes self-test, the RUN indicator flashes, and the SOC indicator
displays according to the current state.
Warning: If there’s no response on the battery indicator or the ALM indicator is always on after
the above operations, please refer to 4.2 Alarm Description and Handling.
2. Use a voltmeter to measure whether the battery terminal voltage of the circuit breaker is more
than 37V, and check whether the voltage polarity is the same as that of the inverter input. If the
measured input has a voltage output more than 37V, it means that the battery has started
working normally.
3. After confirming the voltage and polarity of the battery, close the circuit breaker and turn on the
inverter.
4. Check whether the inverter indicator and battery indicator (communication indicator, status
indicator) are normal. If they are normal, complete the connection between the battery and the
inverter. If the indicator lights are abnormal, please refer to the inverter instruction manual or
contact the dealer.
