This 20kW solar battery system consists of 18*550W solar panels, 1*10kW hybrid inverters, 4*5.12kWh battery modules, totaling a 20kWh battery bank, and paired with necessary solar cables. This 20kw ECE Energy solar system with battery storage can not only power the dryer and stove, heating, washer, dishwasher, and other home appliances, but also start some motors at the same time. The 20 kWh solar battery can be designed as on-grid and off-grid systems. A grid-tied system can charge the batteries at a low rate and sell the surplus electricity to the grid at peak rates. More importantly, coupled with this 20kw solar battery system to store the excess power, it's a reliable power source to accommodate any disruption in daily life.
The high module conversion efficiency of 580Watt Monocrystalline solar cells. The 20 kWh solar battery is designed waterproof, corrosion-resistant aluminum frame for extended outdoor use. Suitable for industrial and professional applications, like caravans, RVs, golf cars, yachts, boats, etc.

Compared with the 10kw battery storage, a 20 kWh solar battery system is configured with 18550W photovoltaic panels. With an average of 4 hours of light a day, 40 KWh a day. This is enough to meet the needs of an average home. How to deal with the huge surplus power from your 20kwh battery storage is a question worth thinking about. A charging pile compatible with photovoltaic charging is the best choice.
The 20kW home solar battery system exist to a certain extent, offering great convenience for customers to use. There is no need to queue up at public charging stations to make sure that electric cars are fully charged when they go out in the morning. Second, charging at home, especially during off-peak hours, is much cheaper than public charging. This integrated 20 kwh battery bank solution transforms surplus solar energy into tangible savings and convenience.
