Off-Grid Solar Power System

Solar Off-grid power system solved the power supply problems for those area without grid coverage or stability grid, the generated electric energy stored in the batteries through by controller, when the user need electricity, the inverter will transfer DC into AC power to the user’s load by transmission line.


These cases are sutable for solar energy resources lll class area
1. Reasonable match on power generation, energy storage, inverter output equipments.
2 Adopt stable power freqenoy inverter with stable output voltage
3. High efficiency solar module with MPPT function charge controller
4, Deep cycle battry with long lifespan
5. Easy to install kow maintenance and Expansion convenient


Inverter with 1KW,Solar panel with 1KW,the inverter coefficient with 0.8.Solar modules and battery on the actual load capacity to make expansion and reduction,adjusted by actual power consumption.
