A repeatedly tripping inverter RCD indicates either a faulty appliance/load or wiring issue on the output side of your inverter.
You can first look at unplugging each appliance/load on the inverter circuit and reset the RCD on your inverter, then plug in each appliance/load again one by one to determine if a certain appliance/load is the cause of the RCD tripping.
If you suspect the inverter may be at fault, it can easily be isolated by disconnecting the two IEC plugs from the inverter and plugging them into each other (make sure that there is no AC power connected to the inverter). This will allow you to by-pass the inverter completely and provide power to the output side of your system directly from a mains power source while you fault find. If the RCD at the mains power source trips, then this will confirm that there is problem on the output side of your system. If the RCD at the mains power does not trip, then there may be an issue with your inverter. Take a photo of your inverter installation and email it to support@enerdrive.com.au
If the appliances/loads are not the issue and you have determined that the inverter is not at fault via the bypass method, this suggests that there may be an issue with the wiring. You should then contact a qualified electrician to inspect and repair the wiring.
