First off I apologize if these questions have been answered but I have read quite a few posts and cant seem to make heads or tails of it. I have done a fair bit of electrical work before, I finished my entire basement myself.
Essentially I am looking to do a small offgrid setup for my RV travel trailer, I am pretty set on two Grape 250W panels, everything I have read about them just glows awesome. But I have read reviews that say they are quite high powered panels and as such require a 24V charger and inverter.
So here in lies my first question, do I need 24V or can I get away with 12V for a setup of 2 250W panels?
Second question is can I get away with just a digital charge controller or do I need a MPPT, if so what would be a suggested MPPT (brand, amp, etc), keep in mind the for this system I will never add any additional panels as I wouldnt have room for them on the trailer.
Third question, what would be an appropriate inverter for this system
and final question, obviously depending on if this is a 24 or 12v setup what sort of battery configuration would I need for something like 1500w ?
Thanks in advance, and feel free to ask me for further details.
