Deye 5 kWh 256 V Lithium Solar Battery SS-F5

Not every high-voltage system needs a tall stack of modules: the Deye SS-F5 delivers 5 kWh at 256 V nominal from a single 45 kg, 470 x 650 x 170 mm unit, operating between 224 and 292 V with high-voltage battery inverters over CAN2.0 or RS485. Its IP65 enclosure and 0-100% humidity rating tolerate harsh placements, and both charging and discharging are specified across the full -20 to 55 degrees Celsius span, so winter performance is in the datasheet rather than in hope. A master-slave BMS with passive balancing supervises the LiFePO4 cells - rated past 6,000 cycles to 70% capacity - and DC arc detection is available as an option. The recommended depth of discharge is 90%, with 10 A recommended current against a 20 A maximum, and up to six units parallel into one system. Wall- or floor-mounted, it reads out SOC and fault codes and carries Deye's stated 10-year warranty. We are an authorised Deye distributor and supply the SS-F5 from our own stock, with technical support before and after the sale.
