My Luminous Zelio+ 1100 Showing “sct” error and nothing is work in my house. “SCT” code on your inverter is ‘check output’ . This error code show inverter for ‘Any Short-Circuit occurred’. So check your Output Cables and all output loads then fiend problem and solved it then restart inverter. Sometimes when inverter board is bad ( damaged) that times also showing same problem so you call Luminous care No (1800 103 3039).
