Now onto the electrical: I have a portable 1KW battery pack/inverter, with a handle and wheels. The batteries were good, but eventually they died, so it became a paperweight...
So I decided to gut it, and fabricate some kind of brackets to install it in the trailer. I have two type 32 AGM batteries, as well as one type 27. I use the type 27 to run the lights and everything 12 volts on the trailer, and use one of the type 31s as backup. The other type 31 will operate the inverter, which will be turned on by a remote switch in the interior whenever 120 volts are needed. When they are not required, then the inverter will be turned off to avoid any phantom current draws.
I had to figure out how to turn off the converter whenever the inverter was being used: I don't want to send power from one battery to the next: very bad for power conservation.
I looked in the panel, and found the hot line feeding the converter, and noticed it was connected to the same breaker that the non-GFI 120V circuit was connected to. I also noticed that there was an empty breaker spot on the panel. How cheap, Dutchmen...
The plan: to tap into the control voltage circuitry of the inverter, and use it to energize a relay that will disable the converter circuit (which I will move to a separate breaker on the panel).
