Starts Big Motors Without Flinching
Big AC units and deep well pumps draw a huge surge when they start up. Some inverters struggle with that. This 8kW Off-grid Outdoor All in One ESS uses a low-frequency inverter. It handles those startup spikes without breaking a sweat.
The inverter output is 8kW. The battery stores 16kWh of energy. The nominal voltage is 51.2V, and the nominal capacity is 314Ah. The cycle life exceeds 6000 cycles.
We have been manufacturing batteries since 2014, giving us 12 years of experience. Our factory in Zhuhai covers 14,000 square meters and employs 230 workers. Our R&D team previously supplied batteries for Siemens and Panasonic.
Low-frequency inverters cost more to build, but they are worth it when you need reliable power.
Built for Remote Locations
This 8kW Off-grid Outdoor All in One ESS operates at 220VAC, 50Hz, sine wave. The AC input voltage ranges from 170VAC to 275VAC. The maximum AC charge current is 40A. The solar input supports up to 5600W at 180VDC. The maximum PV charge current is 100A.
The unit measures 625 × 715 × 940mm. It weighs 227kg net and 310kg gross. The outer package measures 1082 × 1000 × 1108mm. These specifications are based on actual measurements. We inspect every production batch.
