For the curious, otherwise maybe disregard.
So as for my electrical issue.
My off grid system as do many others, has an Auto Generator Start system. Basically programming in some settings related to battery health can trigger a relay that starts the battery and system charges battery rather than inverting. Settings can also terminate this function. My problem is the Aux Relay, my trigger, has a problem in the stack and would malfunction, generator not start and likely the next load surge would bring voltage down to the system shutdown level. Hence no power.
Several work arounds without fixing the bad board. Rewire generator to another trigger/relay. Given size of my system I have at least 2 others. But rerouting the wires would be a PITA.
When this system was installed I kept 2 of my old inverters and had installer wire them in as a separate charging system. It shares same battery bank and some common info but connected to its own generator and control model. Also the ac output is not connected, but it could be its own source.
I did this to be able to run smaller, non propane(cheaper) generator. This newer system with increased capacity has been quite efficient and running generators less than 50 hrs a year and mostly during our rainy season. So when my friend Keith suddenly had a power issue it was a no brainer to pull the Honda out of the system and lend it to him. He now has a nice lithium battery power system and I got the Honda back.
Of course I took advantage of having this 2nd control module (Mate3) and used to troubleshoot my problems, hence the programmed setting are changed.
Thinking of taking the opportunity to relocate placement of the Honda and this will require rerouting control wire. Once back in service, this separate charging station would autostart generator when triggered keeping voltage up and my main system happy, not even knowing there was a potential problem.
OK, too much for some, but I know a couple of you read with interest.

and I’m procrastinating.
