Deye SE-G5.1 Pro-B 5.12kWh 48V LiFePO4 Battery

The SE-G5.1 Pro-B is a 5.12 kWh low-voltage lithium iron phosphate (LiFePO4) battery from Deye, rated 51.2 V and 100 Ah, for 48 V hybrid and off-grid inverters in homes, offices, and shops.

It is rated for more than 6,000 cycles at 90% depth of discharge, which means years of daily charging and discharging, and LiFePO4 chemistry is thermally stable and safe for indoor installation. Up to 64 batteries can be connected in parallel, so a system can start with one or two and grow up to around 327 kWh as needs increase.

Its BMS communicates with Deye and other compatible hybrid inverters so charging is managed correctly.

We size the battery bank to your overnight loads and backup hours, mount the batteries in a rack or stack, and commission them with the inverter.
