Hi All,
I am new to the forums and wanted to first say how helpful the site has been so far just in my research. I am new to solar, so I am trying to spend 10x the time learning before I buy.
The system I am setting up is for a trailer that I leave at my remote property in AZ. The electrical requirements are minimal at this point (furnace, charging phones, etc.) but as I learn more, I plan to expand. The camper has a 4k generator as a backup, but I'd like to avoid running it in the middle of the night because the kids are cold
So far, I'm targeting about 300w worth of panels feeding 220Ah worth of batteries (AGM planned), but I am sizing the wiring for future plans to add batteries and panels as the demand increases.
My question is this....with an MPPT controller, do I need to add any sort of provision for a disconnect or transfer switch when the generator is running and powering the 120VAC - to - DC converter to avoid having dual charging sources? I would assume that the charge controller would see the increase in battery voltage and the lack of demand and pull back its charging, but I cannot find anything concrete to back this up and would rather not burn up my batteries prematurely.
Thanks in advance
