  • Post in thread: Need advice RV 50amp solar only

    In a former life I was an RV tech . 50 Amp RV outlets are split phase 240 . If you run 2x120v from a single phase at the RV outlet you run the very real risk of overloading the neutral wire running from the 50 amp male plug to the breaker box in the RV. I have seen more than a few RVs burn up in...

  • Post in thread: Need advice RV 50amp solar only

    The 50 amp RV system is only split phase up to the breaker box in the RV, everything after the breaker box in the RV 50 amp system runs on 120v so If you can switch the RV wiring between the RV breaker box and a separate solar breaker box you can keep your solar inverter 120v , as long as the...

A breaker (or fuse) would serve no purpose. You would not need a breaker (or fuses) . There are a...
