Off-grid solar system is mainly used for application with relatively-small power consumption, and the areas have no grid network coverage, or the area has grid coverage but grid power is in unstable or outage condition. This system needs batteries to store the electricity. And all the loads shall fully rely on the batteries for power supply.
Poly Solar panel Characteristics
1, High reliability with guaranteed +/-3% output power tolerance
2,The modules can withstand high wind-pressure, snow loads and extreme temperatures
3,Bypass diodes to minimize power loss with shading
4,High and stable conversion efficiency to ensure the highest quality
Feature of controller:
1,Integrated MPPT capability increases PV system efficiency 20%~30%
3, An optional battery temperature sensor ensure precise battery charge.
4, LED displays to indicate the status of charge.
6, Reverse current at night.
7,Three-stage battery charging (bulk,absorption,and float) with optional temperature Compensation.
8, It can improve battery life.
9, Automatic overload protection in both active and passive modes.
10, Microprocessor controlled.
Feature of deep cycle battery:
