The ESS Series is a fully integrated all-in-one home energy storage system that combines a high-capacity LiFePO4 battery, a pure sine wave inverter, and an intelligent MPPT solar charge controller within a single compact enclosure. Engineered for residential use, it seamlessly provides backup power during grid failures and optimizes solar energy utilization by storing surplus PV generation for nighttime or peak-rate periods. Supporting both grid-tied and off-grid operation, the system automatically transitions between modes to ensure uninterrupted power supply. With a wide DC input range for flexible solar panel configurations, multiple AC and DC output ports, and robust IP41 protection, the ESS Series delivers safe, efficient, and versatile energy management for modern homes, apartments, and small commercial spaces.
