Maintenance Guidance

The inverter is easy to maintain. When you encounter the following problems, please refer to the Solutions below, and contact the local distributor if the problem remains unsolved. The following table lists some of the basic problems that may occur during the actual operation as well as their corresponding basic solutions.

NOContentCauseSolutions

1Over loadThe load power exceeds the inverter power or the output port is short-circuited.1. Check whether the load is in compliance with the maximum power of the machine.

2. Cut off all the power and shut down all the machines; disconnect the load and plug in to restart machines, then check whether the load is short circuited if the fault has been eliminated.

2Bat DisconnectThe battery is not connected to the inverter or the battery porthas no output voltage.Check whether there is voltage at BAT port of measuring inverter.

3Bat under vol1. The battery charge is too low.

2. The battery BMS sends an instruction to prohibit discharging.1. If the battery is too low, charge it in time.

2. Check the battery communication protocol

4Bat low volThe battery voltage is lower than the normal workingCharge the battery as soon as possible

5Bus over vol1. The PV input voltage exceeds the MPPT voltage.

2. The load port and the power grid port areconnected inversely.1. Check whether PV input voltage is within MPPT voltage range.

2. Power down the whole machine, and then power up after the display screen goes out.

6BMS Comm. failThere is no normal communication between the battery and the inverter.Check whether the communication between inverter and battery is normal.

7Fan FailPoor contact of fanPower down the whole machine, and then power up after the display screen goes out.
