    SOFAR HYD - Can you diy battery?

    Instructions and all videos I see with them seem to either use a amass or pylontech batteries. My question is, can you use diy bateries with these inverters? If not, is there any hybrid grid tie inverter (legal/export limiting/etc) that allows for diy batteries?

    Cheapo ebay inverters and general advice for a first timer
