Hoymiles launches 5.12 kWh lithium iron phosphate battery for rooftop PV applications

Chinese microinverter maker Hoymiles has unveiled a new lithium iron phosphate (LFP) energy storage system for residential and C&I PV systems.

“The LB-5D-G2 battery offers excellent performance with 5.12 kWh capacity for a single unit and up to 81.92 kWh for 16 batteries running in parallel, suitable for your home and small C&I scenarios,” the company said in a statement.

Each battery module measures 640 mm × 380 mm × 145 mm and weighs 45 kg. It has a rated capacity of 100 Ah, a rated voltage of 51.2 V, and a voltage range of 44.8-58.4 V. The recommended depth of discharge is 90%.

The battery also features IP20-rated protection and a cooling system based on natural convection. It is suitable for wall-mounted and floor-standing deployment and has an expected lifespan of 6,000 cycles.

“There are low-voltage safety features at both the pack and system levels,” the company said. “The battery management system (BMS) includes multiple layers of protection against over-temperature, over-current and overvoltage.”

The new product comes with a standard 5-year warranty, extending to 10 years for PV system owners that also utilize Hoymiles inverters. “The battery supports a wide range of inverter output capacities, so that compatibility is never an issue,” the manufacturer stated.

The system is currently available for sale in the Asia–Pacific (APAC) region.
