Deye SE-F5 Plus 5.12kWh LV LiFePO4 Battery (51.2V, 100Ah)

The Deye SE-F5 Plus is a 5.12kWh, 51.2V, 100Ah lithium iron phosphate (LiFePO4) low-voltage battery for homes and small businesses running 48V hybrid or off-grid inverters.

It is the step up from the standard SE-F5: the same size and currents, with a 90% recommended depth of discharge, charging from -10°C and double the warranted energy throughput. It mounts on a wall, on the floor or stacked up to six high, and banks scale from one module to 32 in parallel (64 with a Deye CAN-Bridge).

Why installers pick this unit

• 5.12kWh per module, 51.2V nominal, 100Ah LiFePO4
• 90% recommended depth of discharge and at least 6,000 cycles (25°C, 70% end of life)
• 120A continuous discharge (150A peak for 10s), 100A continuous charge
• Charges from -10°C and discharges from -20°C
• Scales to 32 modules in parallel (64 with a CAN-Bridge), with auto-networking
• CAN and RS485 BMS comms, Bluetooth app for local monitoring; BMS with active fuse

Residential and small commercial backup, load-shedding and self-consumption systems on 48V hybrid and off-grid inverters, sized in 5.12kWh steps.

Good to know before you quote it

• Indoor product (IP21): install in a dry, ventilated room out of direct sun and rain.
• Battery comms run over CAN or RS485 on the RJ45 port; Deye states the system works with all Deye hybrid inverters. For other inverter brands, check the brand's battery compatibility list.
• Maximum continuous current applies in lithium mode and depends on temperature and state of charge.
• Warranty is 5 or 10 years depending on the installation site, with 16MWh energy throughput; conditions apply per Deye's warranty policy.
• Deye offers several front-panel finishes for the SE-F series; the unit supplied may look different from the photo.
