Output Relay Fault
The output relay fault is a very common problem; sometimes it means the relays need to be replaced, sometimes it will be the output filter capacitors collapsing; either way the inverter will need to be sent to us for repair. When we repair the relays we use OMRON relays, there are a robust industry leading relay and will give much better service life.
There is no life in the inverter
By this I mean there is nothing on the screen, no lights are on. This will be the internal power supply on the inverter; the power supply is famous for collapsing prematurely. The good news is we can refurbish the power supply and get it working properly, while we are fixing the power supply we will also make a few minor modifications to it so it will last longer
