Figure 4-1
After pressing the power button, if the battery status indicator on the front panel
continues to be red, please refer to the "P24 Alarm description and processing ". If the
failure cannot be eliminated, please contact the dealer timely.
Use a voltmeter to measure whether the voltage of the circuit breaker battery access
terminal is higher than 44.8V, and check whether the voltage polarity is consistent with
the inverter input polarity. If the circuit breaker battery input terminal has a voltage
output and is greater than 44.8V, then the battery begun to work normally.
After confirming that the battery output voltage and polarity are correct, turn on the
inverter, close the circuit breaker.
Check if the indicator of the inverter and battery connection (communication indicator
and battery access status indicator) is normal. If it is normal, successfully complete the
connection between the battery and the inverter. If the indicator light is abnormal,
please refer to the inverter manual for the cause or contact the dealer.
