Deye 2.56 kWh 12.8 V Lithium Solar Battery WD-G12200

When a 12 V design outgrows 100 Ah, the Deye WD-G12200 doubles everything that matters: 200 Ah of capacity (2.56 kWh), a 2P4S prismatic LiFePO4 pack, 200 A of continuous charge and discharge and a 300 A peak for demanding surges. It stays manageable at 21 kg and 471 x 348 x 160 mm, mounting on the floor or in a stack. System building mirrors its smaller sibling: four units in series create a 51.2 V nominal bank, ten in parallel multiply capacity, and RS485 carries communication while an LED shows state of charge. The recommended depth of discharge is 80% against a cycle rating beyond 6,000 cycles to 70% capacity, across an 11.2-14.6 V operating window. Deye specifies discharge from -20 to 55 degrees Celsius, storage at 0-35, humidity to 95% and altitude below 2,000 m, with UN38.3 certification and an MSDS published for transport and handling. We are an authorised Deye distributor and supply the WD-G12200 from our own stock, with technical support before and after the sale.
