10.1 Error code
String type inverter doesn’t need regular maintenance. However,debris or dust will affect heat
sink’s thermal performance. It is be�er to clean it with a so� 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.
Inverter has been designed in accordance with interna�onal grid �ed standards for safety,
and electromagne�c compa�bility requirements. Before delivering to the customer the
inverter has been subjected to several tests to ensure its op�mal opera�on and reliability.
If there is any failure,the LCD screen will display an alarm message. In this case,the inverter
may stop feeding energy into the grid. The alarm descrip�on and their corresponding alarm
messages are listed Table 10.1
.
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:
No solvent, abrasive materials or corrosive materials can be used for cleaning
any parts of the inverter.
