The Cworth Energy 20 kWh, 51.2 V solar battery (≈ 400Ah) is a high-capacity, deep-cycle lithium-ion (often LiFePO₄) unit designed for heavy duty solar backup applications. It delivers stable voltage, high energy density, and longer cycle life compared to lead-acid batteries. Integrated with a battery management system (BMS) for protection against overcharge, overdischarge, thermal events and short circuits, it is ideal for off-grid, residential or commercial solar systems.
