Quattro 5k toggle switch

[Reidneck]

Hey there. I have 3 quattro 5k inverters. Initially intended for 3 phase. I ran into an issue of my on/off/charge switch not working during initial testing rebooting. The switch felt softer/not as defined click after several uses. After some misguidance from vendor i found that i can only use my 3 pahse while fully offgrid as i do not have 3 phase shore power and can only use my single phase generator/shore power for single phase (america split phase) supply/pass through. So that i could get up and running i wired in just 2 of my inverters and disabled the 3rd one from program and disconnected ve.direct cable. Im pretty sure its a physical problem with the switch. Towards the end of my trying it quit lighting up in on mode and some times it would light up in charge mode but finally it wont light up at all no matter what. As i recall the inverter had to be physically switched off and on at times during setup procedures. Im using a cerbo gx. The main question here is there a way to wire in a 3 way remote physical switch so i dont have to replace my inverter. I am still under warranty but dont mind doing this if possible instead of replacing. I know there have been several software upgrades since i did this so maybe its not going to be a problem. I have figured out some things and want to wire in my 3rd inverter but i am currently 100% off grid and i dont want to do it if i cant go back live with it without using the physical on/off/charge button during the setup process. I had to mount my inverters a little high do to my mechanical room layout so a lower remote switch on each inverter would be nice anyhow. Any advice. Thanks
