10.Error informa�on and processing

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.

9. Repair and Maintenance

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.  

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.

Please set the proper grid parameters according to the requirements of your current country's 

grid regula�ons.If you are not clear about it, please consult your installer.
