Deye GB-W 11.7kWh 51.2V LiFePO4 High Voltage Stackable Battery Module

The Deye GB-W is a stackable 11.7kWh LiFePO4 battery module for indoor commercial and industrial energy storage. Each module holds 230Ah at 51.2V nominal and stacks cable-free — no tools, no wiring harness — so a full cluster goes up in a fraction of the time a conventional rack system takes.

Clusters scale from 5 to 16 modules, giving 58.8kWh to 188.4kWh per stack at 256–819.2Vdc, with up to 169.5kWh usable at 90% depth of discharge. Run up to 16 clusters in parallel and the system reaches 3MWh. Cluster-, pack- and cell-level balancing algorithms allow modules to be replaced or added without matching batch or age.

1C continuous charge and discharge — 230A, with 322A peak for one second — suits high-load sites and fast-charge duty cycles. Intelligent thermal management runs independent fans at pack level and holds cell temperature spread within 5°C. Millimetre-grade filtered airflow strips dust before it reaches the cells, and a detachable maintenance cover allows service directly on the cluster.

C4 anti-corrosion coating handles humid and industrial environments. Rated for 6000+ cycles at 70% end-of-life retention with a 10-year warranty, and compatible with Deye power units from 30kW to 125kW.
