Solis alarm code resolution guide

Solis inverters are designed following essential international grid-tied standards and safety compatibility requirements. If a failure occurs within the system, the LCD screen displays particular Ginlong/ Solis alarm codes. The Ginlong/ Solis alarm codes are less extensive than many other grid-tied inverters but are straightforward to interpret and digest. This page will provide all Ginlong/ Solis alarm codes that you’re likely to experience in an error code instance.

Find your Ginlong/ Solis alarm codes with ease, follow this process; 

1. Record the message/code displayed on the inverter. 

2. Jump to the relevant Solis inverter alarm message/code located in the table below.

3. Select relevant alarm message/code to access the failure description and suggestions on what to do.

Solis inverters have undergone rigorous testing to meet globally recognised quality standards. Therefore, if you’re experiencing specific Solis alarm codes, chances are something external could be influencing the inverter’s ability to perform. With inverters tied to the grid, they must work under the influence of the solar array, load, and grid network while keeping the equipment and user safe from harm. So extensive safety features are necessary to be in place and notify the user when an event has occurred.
