Midea Hiconics presents new three-phase residential storage systems

Midea Hiconics, the solar storage and inverters subsidiary of Chinese electrical appliance manufacturer Midea Group, has released new three-phase residential energy storage systems.

Dubbed Hienergy Series G2, the new product line offers a PV input range from 10 kW to 30 kW and a storage capacity spanning from 5 kWh to 20 kWh.

“With DC input current up to 20 A and 200% PV input power capability, the system ensures maximum solar energy utilization. Advanced shadow scan technology further optimizes production, even in challenging conditions,” the company said in a statement. “Homeowners benefit from an industry-leading 25A EPS output current, guaranteeing a seamless power supply during outages.”

On the AC output side, the system can offer from 5 kW to 16.5 kW, depending on the model. All models have two maximum power point trackers (MPPTs), with one string per MPPT. MPPT efficiency is rated at 99.9%, and maximum efficiency is rated at 97.5%.

“For enhanced grid interaction and control, the system is virtual power plant (VPP)-ready, enabling participation in virtual power plants,” Midea Hiconics added. “It offers an ultra-fast <10ms on-grid to off-grid transition and supports up to 6 PCS parallel operation for scalable energy solutions.”

The storage system uses lithium iron phosphate (LFP) batteries with a nominal capacity of 5.12 KWh. Each system can be paired with one to four battery modules, bringing its total capacity up to 20.48 kWh. In addition, two systems can be connected in parallel, resulting in a storage capacity of over 40 kWh.

“Designed for effortless integration, the Hienergy G2 supports smart swap battery technology, AC coupling, and peak shaving for cost-effective energy management,” the company concluded. “Its intelligent IV curve diagnosis enhances system efficiency, while an ultra-fast installation (<15 min) and commissioning (<5 min) minimize setup time.”
