Product Description
The UEI-500kW/1892kWh PV+ESS system is a high-capacity, pre-engineered energy storage solution designed for industrial and commercial facilities. Built inside a 40HQ container, the system integrates solar PV, lithium iron phosphate (LiFePO₄) batteries, hybrid inverter (PCS), EMS, and all auxiliary systems for seamless deployment.
The battery storage section contains 12 high-voltage clusters (563.2V, 280Ah each), totaling 1892kWh. Paired with 720pcs of 720W high-efficiency bifacial TOPCon modules, it can deliver up to 2,000–3,000kWh/day in solar output.
On the inverter side, the hybrid PCS integrates 10 MPPTs for high granularity tracking and achieves up to 550kVA output. The EMS platform allows load dispatch, real-time control, peak shaving, demand response, and black-start functionality. It's a turnkey “grid + battery + solar” solution for reducing electricity costs and ensuring backup power.
