HM-Series HM2-Series

The HM15 is a heavy-duty energy storage solution designed for users requiring maximum power and capacity. With a nominal capacity of 304Ah, this single unit delivers a massive 15.5kWh of usable energy, making it one of the most energy-dense options in its class. It is engineered to power larger homes or small commercial setups, reducing the need to stack multiple smaller batteries.

Housed in a durable IP55 metal enclosure, the HM15 utilizes a 16S1P configuration with advanced 304Ah prismatic cells. This design allows for a high continuous discharge rate of 200A, ensuring it can handle heavy inductive loads (like air conditioners or pumps) without tripping. The integrated Smart BMS provides comprehensive protection and communicates seamlessly with inverters via CAN/RS485, ensuring your system runs safely and efficiently.
