Growatt introduces high-voltage battery for residential, small C&I solar energy – SPE

By ESS news

Chinese inverter and battery manufacturer Growatt has unveiled a new high-voltage energy storage system tailored for residential and small commercial solar applications.

The APX HV Battery 2.0 builds on the company’s modular APX architecture. “Existing APX users can freely combine new and previous generation battery modules within one system, protecting previous investments,” the company said in a statement. “The platform also supports mixed state-of-charge (SOC) operation, module-level energy optimization and a unified master module compatible with both single-phase and three-phase systems, providing unparalleled adaptability for all applications.”

The system supports flexible energy storage capacities from 5 kWh to 30 kWh via a unified base that can accommodate up to six modules. The rated voltage range and output power are scalable with capacity, with single-phase configurations capable of delivering up to 10 kW of continuous power and three-phase installations capable of delivering up to 15 kW

The 5 kWh unit has a maximum output power of 2.5 kW and an operating voltage range of 350 V to 550 V. It measures 590 mm x 365 mm x 255 mm and weighs 51 kg.

The new product is built around the chemistry of lithium iron phosphate (LiFePO₄) and is IP66 rated for ingress protection. The operating temperature range of –20 C to 55 C and the multi-layer safety architecture, including module-level aerosol fire suppression and integrated heating film.

“The system features a stacked, cable-free design and enables a true plug-and-play installation. Integrated handles and a compact footprint further simplify on-site operation, deployment and commissioning,” the manufacturer said. “The result is faster installation, fewer errors and less troubleshooting, allowing installers to complete projects with more confidence and efficiency.”
