What does L1 Voltage High S mean on my SAJ Suntrio-TL?
- DDebra DoughertySep 12, 2025
An L1 Voltage High S error on your SAJ Inverter can occur if the local grid voltage is beyond the permitted range or if there are connection problems between the grid and the inverter. Check the Grid Compliance of the inverter and Grid voltage. If everything appears correct, further assistance is needed.
