Huawei hybrid power solution PowerCube1000, which consist of three main hybrid series: solar hybrid, diesel hybrid, and grid hybrid. Solar hybrid means the main energy source comes from solar energy. Solar hybrid series includes pure solar, solar hybrid with D.G., solar hybrid with grid or solar hybrid with grid and D.G. Diesel hybrid means the main energy source comes from diesel fuel. Diesel hybrid series is the hybrid power system between diesel generator and batteries. By connecting in solar power or grid power, diesel hybrid easily evolves to solar hybrid. Grid hybrid means the main power source is grid electricity. Grid hybrid series includes G2 advanced fast charging; G3 enhanced fast charging, and G4 standard fast charging.
