Bill, try to diagnose the problem down to the remote or the inverter being the problem. There should be a connecting cable between the two. If you disconnect it, then you can determine if the inverter is working properly or not. If you have to remove the inverter because it continues to produce 120 volts from batteries when turned off, be sure to disconnect battery bank before proceeding with removal. Mark all wiring very well so when you get it back sevaral weeks later you can reinstall it correctly. You will need to include with the inverter the battery cables feeding it. Hopefully you will find that the remote control panel switch is the culprit as it is much easier to repair. Good luck and keep us informed.
