WHES releases new C&I storage system series

Chinese storage solutions specialist WHES has released a new series of C&I storage systems. The PowerCore Series 50 kW/100 kWh includes four models, each integrating storage and a hybrid inverter.

“The system allows for on/off-grid parallel connection of up to 6 units, meeting various energy storage capacity needs. With a 10ms seamless switching time, it ensures uninterrupted operation of critical loads such as factory production lines and farm irrigation systems,” the company said in a statement. “Its compact and silent design allows for flexible integration in diverse environments like communities and office buildings, and it is compatible with diesel generators.”

The first model accepts 59.8 kW of PV input and delivers 29.9 kW of AC output. The next handles 60 kW input with 30 kW output, while the two largest models support 80 kW and 96 kW of PV input, delivering 40 kW and 50 kW of output, respectively. Storage capacity across the range spans from 57 kWh to 100 kWh.

WHES said the system supports 200% PV overloading and includes four maximum power point trackers (MPPT) with a 20 A single-string PV input current, allowing it to adapt to complex rooftop conditions and improve solar energy utilization. It also supports 100% three-phase unbalanced output to manage uneven load conditions and increase self-consumption.

The system measures 1,070 mm × 1,150 mm × 2,250 mm and weighs about 1.2 tons. It operates in temperatures from -20 C to 55 C and at altitudes up to 2,000 m. The battery cabinet has an IP55 protection rating, while the inverter is rated IP66.
