250kW Solar + 631kWh Energy Storage Product Description
This 250kW solar + 631kWh energy storage system is a high-performance turnkey solution tailored for commercial and industrial users aiming for energy cost reduction, sustainability, and grid independence.
At its core is a 250kW three-phase hybrid inverter capable of delivering up to 275kVA even in off-grid scenarios. It supports a PV input voltage range of 250–850V, with 5 independent MPPTs to maximize generation.
Energy storage is handled by 4 lithium battery clusters, each 157.7kWh, totaling 631kWh, with a voltage range of 492.8V to 633.6V. All connected through a battery combiner cabinet for safe and efficient distribution.
The system is designed for daily production between 1000–1500kWh, supported by 360pcs of 720W Topcon solar panels, mounted on a robust ground system. All components are CE/IEC certified and designed for seamless integration, with options for AC combiner, PV combiner, and advanced EMS monitoring.
Ideal for factories, logistics centers, agricultural operations, and remote installations.
