SunGoldPower SG48100P rack review
SunGoldPower 48V 100Ah Server Rack LiFePO4 Battery (SG48100P)
By Tom Calder
SunGoldPower sells this 51.2V 100Ah server-rack battery with an LCD and a 10-year warranty, and names UL 1973 and UL 9540A in its listing. Its CAN, RS485 and RS232 ports are listed as compatible with inverters from Growatt, Deye, Victron, Schneider and others. A 48V rack battery is part of an installed system: hire a licensed electrician and get any permits your local authority requires.
