Growatt HOPE 5.5L-A1 5.5kWh 48V LiFePO4 Battery

The Growatt HOPE 5.5L-A1 is a 5.5 kWh low-voltage battery for 48 V hybrid and off-grid inverters, such as the Growatt SPF range. It is rated 51.2 V and 106 Ah, and operates between 40 and 58.4 V.

It uses cobalt-free lithium iron phosphate cells, which are thermally stable and long-lived, and is rated for 6,000 or more cycles at 93% depth of discharge, giving about 5.1 kWh of usable energy per cycle. It delivers 100 A continuously, enough to support a 5 kW inverter at full load.

Several batteries can be combined for more backup time.

We size the battery bank to your overnight loads, install it with the inverter, and set the battery parameters so charging is managed correctly.
