10.Error information and processing
String type inverter doesn't need regular maintenance. However, debris or dust will affect
heat sink's thermal performance. It is better to clean it with a soft brush.If the surface is
too dirty and affect the reading of LCD and LED lamp, you can use wet cloth to clean it up.
In the case of failure the LCD screen will display an alarm message. In this case the inverter
may stop feeding energy into the grid. The alarm description and their corresponding
alarm messages are listed Table 9.1.
Three-phase string inverters are designed according to grid-connected operating
standards. It meets safety requirements and electromagnetic compatibility requirements.
Before leaving the factory, the inverter has undergone several rigorous tests to ensure that
it can be operated reliably and permanently.
Warning:
When the device is running, the local temperature is too high and the
touch can cause burns. Turn off the inverter and wait for it cooling,
then you can clean and maintain.
Warning:
When cleaning any part of the inverter, no solvent, abrasive materials
or corrosive materials shall be used for cleaning.
