I'll try to keep this short. I have a SMB installed Tripp-lite model MRV2012 inverter/charger. Last fall we had to abort a trip because it failed. It would cycle up, the fan would spin and then it would shut down. I went through all the testing/restart procedures to no avail. A month or so later I take it to SMB Austin, the builders and guess what IT WON'T FAIL. I was unhappy for several reasons one of which is that I live in the Dallas area. Anyhow, I keep the van plugged in and everything has been working fine, even started right up earlier this week when I was doing some cleaning. Went out today and van battery was low, had to jump start the van. Of course the house batteries were down also. Got it started, turned on the DC switch after awhile and things seem to be working. Drove to Ft Worth and back and somewhere on the return trip things went haywire again.
Sooo, as I was checking things again I noticed that one of my two batteries boxes was pretty hot, the other seemed fine. I'm really confused now. I sure don't trust the inverter at the moment but now I'm wondering if I have a bad battery and it's screwing things up? I'm pretty sure that we have crossed the threshold of my expertise. BTW I can wire a 3 way AC switch but I'm lost here
Any ideas/thoughts would be appreciated. Oh, I do have a converter on hand to replace the inverter if necessary.
