Light Enough for One Person to Move
Some places only need a small amount of power. A weekend cabin. A small campsite. A toolshed. A 3kW system covers the basics.
This 3kW Off-grid Outdoor All in One ESS is the lightest model in our lineup. The inverter output is 3kW. The battery stores 5kWh of energy. The nominal voltage is 25.6V, and the nominal capacity is 200Ah. The cycle life exceeds 6000 cycles.
We have been manufacturing these systems since 2014, giving us 12 years of experience. Our Zhuhai factory covers 14,000 square meters and employs 230 workers. Our engineering team previously developed phone batteries for Siemens and Panasonic.
This unit weighs only 115kg net. One person can move it with a hand truck. Installation is straightforward.
Perfect for Small Cabins and Camping
This 3kW Off-grid Outdoor All in One ESS outputs 220VAC, 50Hz, sine wave. The AC input voltage ranges from 170VAC to 275VAC. The maximum AC charge current is 30A. The solar input supports up to 1680W at 120VDC. The maximum PV charge current is 60A.
The unit measures 525 × 715 × 800mm. The net weight is 115kg, and the gross weight is 183kg. The outer package measures 882 × 1000 × 1008mm. Its compact size makes transportation and installation easier. The low-frequency inverter still provides excellent surge capacity for small motors.
