Maintenance and Troubleshooting

10.1 Routine Maintenance

Normally, the inverter and battery pack need no maintenance or calibration.
However, in order to maintain the accuracy of the SOC, it is recommended to perform a
full charge calibration for SOC (charging battery until the charging power is 0) on the
battery at regular intervals (such as two weeks).
Disconnect the inverter and battery pack from all power sources before cleaning. Clean
the housing, cover and display with a soft cloth.
To ensure that the inverter and battery pack can operate properly in the long term, you
are advised to perform routine maintenance on it as described in this chapter.
