So assuming the calculations are done correctly, one of the systems that we came up with requires 2000Ah batteries x 48VDC. Of course we would need several charge controllers and pv arrays to charge that.
The question now is, would it be better to have several smaller battery banks wired in parallel for output (but fed by their own individual pv arrays and charge controller) or a single large battery bank fed by the same as above individual pv arrays and charge controllers wired in parallel into the single battery bank?
Thank you very much. We're getting conflicting answers from the battery guys and from the solar charge controller guys (Outback and Schneider).
