BYD Battery Box Premium HVB 2.97kWh Lithium Battery

"The BYD Battery Box Premium HVB 2.97kWh Lithium Battery is a high-voltage, modular energy storage module designed for scalable residential and light commercial solar, backup and off-grid systems. Built using safe and durable Lithium Iron Phosphate (LFP) chemistry, the HVB platform delivers high efficiency, long service life and excellent safety credentials.

Each 2.97kWh module stacks vertically to form an HVB tower, allowing flexible system sizing from small domestic installations to larger commercial projects. Up to three towers can be connected in parallel, enabling total storage capacities of up to 89.07kWh. The true high-voltage architecture maximises round-trip efficiency and ensures compatibility with modern high-voltage hybrid and battery inverters.
