Update inverter firmware

There are two ways to update the firmware:

• Locally via the USB port of the inverter. Procedure including of installation files here.
• Remote update. This can only be done through SOLSOL technical support in exceptional cases. A prerequisite for the update is that the WiFi router is not connected to the UPS output of the inverter. This is necessary because during the update the inverter is rebooted and the electrical power supply (EPS) may fail.

Note: In case of incorrect inverter operation, it is always necessary to check the current firmware version and correct parameter settings for the required function.
