Deye 1.28 kWh 12.8 V Lithium Solar Battery WD-G12100 features

A 12 V building block

12.8 V nominal and 100 Ah - 1.28 kWh - from prismatic LiFePO4 cells in a 1P4S pack.

Just 11 kg

A 310 x 298 x 160 mm case light enough for one person to carry and position.

200 A peak headroom

100 A of continuous charge and discharge, with a 200 A peak for surge moments.

Series to 51.2 V

Four units in series form a 51.2 V nominal system; up to ten units run in parallel.

6,000-cycle endurance

Rated beyond 6,000 cycles to 70% capacity at the recommended 80% depth of discharge.

RS485 plus LED

RS485 communication with LED indication of state of charge and operation.

About the Deye 1.28 kWh 12.8 V Lithium Solar Battery WD-G12100

Small systems deserve real LiFePO4 engineering too: the Deye WD-G12100 packs 100 Ah - 1.28 kWh - into an 11 kg, 310 x 298 x 160 mm case built on prismatic cells in a 1P4S configuration. It sustains 100 A of charge and discharge with a 200 A peak, leaving headroom for inverter surges in compact installations. Flexibility is the point: up to four units wire in series to build a 51.2 V bank, up to ten run in parallel, and RS485 communication plus an LED keep state of charge visible. The recommended depth of discharge is 80%, cycle life exceeds 6,000 cycles to 70% capacity, and the operating window spans 11.2-14.6 V. Charging is specified from 0 to 55 degrees Celsius and discharging from -20 to 55, at altitudes up to 2,000 m and humidity to 95%. Floor and stack mounting keep placement simple, and the pack is certified to UN38.3 with an MSDS available. We are an authorised Deye distributor and supply the WD-G12100 from our own stock, with technical support before and after the sale.
