3.Use a voltmeter to measure whether the voltage across the BAT + / BAT- terminals of
the inverter is higher than 44.8V, and check whether the voltage polarity is
consistent with the input polarity of the inverter. If the voltage across the terminals
BAT + / BAT- of the inverter is higher than 44.8V, which means the battery has
begun to work normally.
4.After confirm the battery output voltage and polarity are correct, turn on the inverter,
then turn on the circuit breaker switch.
5.Check whether the indicator light for the inverter and the battery connection (the
communication indicator and the battery access status indicator) is in normal
condition. If normal, the connection between the battery and the inverter is
