residential solar power system

2.24KW Off-Grid Household Solar System for Daily Power Consumption 8KWH
 
1> System Description

Off-grid PV system convert sun radiation energy into direct current produced by solar panels, and charge-discharges to the battery through controller, then provides power to DC loads or provides power to AC loads through inverter, with/without connection to state grid. The system consists of PV array, charge controller, battery, off-grid inverter and so on.

2> Application
It is used in harsh area such as plateau, islands, remote mountain areas and field working, as well as city area where there's lack of grid power. It also can be applied in communication base station(GSM site), advertising lamp box, street lamp and so on.
