About the Deye 5.12 kWh 51.2 V Lithium Solar Battery SE-G5.1

The Deye SE-G5.1 is a 5.12 kWh lithium iron phosphate battery module rated 100 Ah at 51.2 V nominal, built as a 1P16S pack that charges and discharges continuously at 50 A (0.5C) and returns 4.1 kWh of usable energy at the recommended 80% depth of discharge. At 44 kg and 440 x 133 x 540 mm, a single module rack-mounts, floor-stacks or wall-mounts, and up to 64 modules run in parallel to a stated system maximum of 327 kWh - 32 of them without a CAN-Box, with one module the minimum. It talks to low-voltage hybrid inverters over CAN2.0 and RS485 inside a 44.8-57.6 V operating window, peaks at 100 A for ten seconds, and puts a built-in circuit breaker over its BMS protection. Cells are rated beyond 6,000 cycles to 70% end-of-life capacity and Deye states a 10-year warranty. The IP20 enclosure suits indoor rooms below 2,000 m of altitude. We are an authorised Deye distributor and supply the SE-G5.1 from our own stock.
