My RV repair/update shop that I own has installed many systems over the years. Our normal way is to use a single charge controller for up to 1kw array. Being a mobile application we have always installed in parallel. My question is would installing a charge controller for each panel versus using one large controller work?
I'm plaining on a 2kw system, and the biggest downside I can see in my head is the physical space needed for 10 controllers. But doing some reading on this forum I'm now starting to wonder about controllers prematurely going into float before the batteries are fully charged.
