Troubleshooting and Resetting Your Solar King SLK Inverter

The Solar King SLK inverter range will detect major internal issues within itself, displaying a fault light until the problem is resolved. In this case you should contact Solargain to inspect your inverter.

In the morning and late afternoon as the inverter is turning on or off you may notice a red light and hear a clicking noise. These are normal functions of the inverter – there’s no need to worry.

If your inverter continues to display a red light throughout the day you should reset it. Instructions explaining how to do this are available here.

If, after resetting, the red light remains on, note down the error code displayed on the screen as well as the serial number from the sticker located on the side of your inverter and then contact our service team. We’ll happily assist you to resolve the issue.
