Deye's modular C&I ESS solution assembles 100/125 kW PCS modules with integrated EMS, 200 kWp 8-tracker MPPT modules, a 500 kW static transfer switch and BOS-B Pro-A3 battery clusters of up to 257.23 kWh (819.2 V, 314 Ah). Each PCS supports up to 16 battery clusters, and paralleling PCS and STS modules scales the plant to 2.5 MW.

The STS provides UPS-level on/off-grid switching in under 10 ms and the PCS reaches 98.5% maximum efficiency with zero-export, time-of-use, peak-shaving and demand-management functions. LiFePO4 cells with integrated aerosol fire suppression, 90% DoD, ≥6,000 cycles and a 10-year battery warranty round out the package, with local touchscreen control and remote monitoring via Deye Cloud.
