I would like to share my inverter wiring solution, after having considered all the pros and cons as they relate to accommodating our specific needs; other people will have different ideas or needs.

In the beginning, I was reluctant to install an inverter subpanel, but in the end I decided I need one if I want maximum operating flexibility. With my installation, I wanted the ability of running the AC section of our rig in several different operating modes, which are listed below. Modes 2) and up are all designed for situations with no or insufficient shore power (recently, we were at a campsite where the alleged 30 amp breaker tripped at less than 20 amps!).

1)      Main panel (MP) and inverter subpanel (SP) both on shore power (the “standard” way)

2)      MP and SP both on generator (a mobile 3,600 watt Boliy)

3)      MP on shore and SP on generator

4)      MP on shore and SP on inverter

5)      MP on generator and SP on inverter

6)      SP on inverter

Considering the various climate and campground/dry camping conditions you may find yourselves in when fulltiming, we wanted this kind of flexibility.

We spent less than $200 for all materials needed (subpanel, transfer switch, changeover switch, 30 amp inlet, breakers, wiring materials). [@Terry: Yes, we installed a generator inlet at the front like you suggested; it’s way more convenient than messing with a 50ft cord all the way to the end of the rig!].

If someone is interested in the wiring diagram, please PM me and I will email it.
