Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in the UAE that rests with the local authorities (DEWA, ADDC, SEWA). Confirm the grid code, import requirements and any local certification with them, or with us, before you order.

Frequently Asked Questions
What is the Deye SE-G5.1 Pro-B?
A 5.12 kWh LiFePO4 battery module rated 51.2 V nominal and 100 Ah, in a naturally cooled 440 x 133 x 540 mm chassis weighing 45 kg that mounts in a 19-inch rack, on a wall or on the floor. Deye states a 10-year warranty.
How much of the SE-G5.1 Pro-B's 5.12 kWh is usable?
All of it: usable energy is listed at the full 5.12 kWh, with a recommended depth of discharge of 90%. The cells are rated beyond 6,000 cycles and 16 MWh of throughput, down to a 70% end-of-life capacity.
What charge and discharge current does the SE-G5.1 Pro-B support?
Maximum charge and maximum discharge are both 100 A, with a 150 A discharge peak, and Deye recommends 50 A for continuous charge and discharge. A built-in 125 A 2P 60 Vdc breaker protects the DC connection.
How many SE-G5.1 Pro-B modules can run in parallel?
One module is the minimum, and up to 64 can be paralleled - 32 of them without external hardware - for a stated maximum of 327 kWh. Modules communicate over CAN2.0 and RS485.
