48V LiFePO4 Batteries

48V LiFePO4 batteries are the standard for home solar, backup and off-grid systems. At 48V (51.2V nominal), a battery bank carries a quarter of the current of a 12V bank at the same power, so wiring is thinner and losses are lower, and most hybrid and off-grid inverters are built for it.

Battery Capacity Format Best for
GSL 14.34 kWh wall-mount 14.34 kWh (280Ah) Indoor wall-mount; self-heating version available Home backup and off-grid homes; up to 16 in parallel
GSL Energy Powerlite 5 kWh 5.12 kWh (100Ah) Compact module Smaller systems and cottages; expand by adding modules
Growatt ALP LV-US 5 kWh 5 kWh Stackable module Growatt inverter systems

Choosing a 48V battery

  • Inverter communication: choose a battery that communicates with your inverter over CAN or RS485 (closed loop), so the inverter charges it correctly. Ask us to confirm your inverter model.
  • Capacity and expansion: start with the storage you need now and check how many units can run in parallel later.
  • Cold weather: LiFePO4 can't be charged below 0°C. Install indoors in a heated space, or choose a self-heating battery for cottages and unheated garages.
  • Safety documents: ask for UL 1973 and UL 9540A test reports; rebate programs and inspectors may require them.
