About the Deye 5.12 kWh 51.2 V Lithium Solar Battery SE-F5-L

Start with what today's loads need and leave the ceiling high: the Deye SE-F5-L puts 5.12 kWh of 51.2 V LiFePO4 storage into a 370 x 548 x 140 mm pack weighing just 41 kg, so a single installer can hang it on a wall, set it on the floor or add it to a stack. At the recommended 80% depth of discharge it yields 4.1 kWh per cycle, backed by a rating of more than 6,000 cycles to 70% capacity and 8 MWh of energy throughput. It charges at up to 100 A and discharges at up to 120 A - 150 A for ten-second peaks - around a 1.5 kW rated DC output. As consumption grows, up to 32 packs run in parallel, topping out at 163.84 kWh - or 64 packs with a CAN-Bridge. CAN2.0, RS485, Bluetooth and an app cover inverter communication and monitoring, and Deye states a 10-year warranty for this model. We are an authorised Deye distributor and supply the SE-F5-L from our own stock, with technical support before and after the sale.

Frequently Asked Questions

What systems does the SE-F5-L connect to?

The SE-F5-L is a 51.2 V low-voltage battery with a 44.8-57.6 V operating window; it talks to hybrid inverters over CAN2.0 or RS485.

Can I add more SE-F5-L packs later?

Yes - the design allows 32 packs in parallel for a bank of 163.84 kWh, and up to 64 packs with a CAN-Bridge.

How much power can one SE-F5-L sustain?

It is rated for 1.5 kW of DC power, with discharge current up to 120 A continuously and 150 A for ten-second peaks.

What depth of discharge should I plan with on the SE-F5-L?

Deye recommends 80% for this model, which corresponds to the 4.1 kWh usable figure; the recommended charge and discharge current is 30 A.

Does the SE-F5-L work outdoors or in the cold?

The enclosure is IP21, so it needs a protected location; charging is specified from 0 to 55 degrees Celsius and discharge from -20 to 55 degrees Celsius.
