Renewable Energy Sources Complete Solar Energy Systems Kit 5KW 5000W 48V Solar Power System For Home

How does it work?
Solar power system can make electricity power from sunshine, it is total free energy. The system is with inner charger and automatic switch, when solar power not enough, it can switch automatically and take use off battery power to run load, when solar power on, it also can switch automatically and take use of solar power. At the same time charging battery, even no solar and battery power, it will take power from grid.
