My RV isn't too big, but I scored a deal on 4 REC 405W panels. These are near top of the line! Right now, I've only got two mounted to the roof, but they've been incredible. In cool, sunny weather, I regularly get above the rates power coming in!

The panels are running into twin MPP Solar 3048LV-MKs, set up to run in split phase. They are charging one DIY 16 105Ah cell lifepo4 battery pack managed by a JKBMS. More storage will happen later this year. I'm in process of re-wiring the trailer for 240V so I can run a higher efficiency mini-split (the roof top AC is terribly inefficient!) to provide much better heating and cooling in the space and also being able to support BTC miners that I intend to use to provide radiant heat (imagine having a heated floor in an RV!!!) and possibly pre-heating hot water for washing and showering.

With more storage and the full 4 panel array, I can pretty easily cover all even with moderate heat and cooling loads via the battery and panels. After I move to my own property, I'll be able to build and utilize a wood gassifier to run a generator and charge the batteries if needed. I will eventually need more panels to cover power in the winter, but, that can come later.

This whole thing is going to be versatile, flexible, and pretty friggon' rad!
