Zero-emission, noise-free, and easy-to-install commercial off-grid solar power system.

Sunpal Photovoltaic off-grid solar power generation system design and selection, photovoltaic off-grid power solar systems are generally divided into small solar DC systems, small and medium-sized off-grid power solar systems, and large-scale off-grid power solar systems. Our small and medium-sized off-grid systems are mainly to solve the electricity demand of families, schools and small factories; the large-scale off-grid power solar system mainly solves the electricity demand of the whole village and the whole island. This system is now also a micro-grid system. The overall optional range is 10KW to 1MW.

Product Benefits 

• Storing the electricity generated by solar modules

• Substantial reduction in electricity investment

• Realize return on capital and profit in the short term

Common Application 

• Integrate with building installation

• Mostly used for island electricity

• Electricity demand for life and work in schools or small factories

Off Grid Inverter

Gel Battery

The main components of lead-acid batteries are lead and lead compounds, and the lead content is as high as 60% of the total battery mass. The residual value of used batteries is high, and the recycling price is more than 30% of that of new batteries, so the overall cost of lead-acid batteries is low.

High compatibility & adjustability，Support both screw pile & concrete base，Flexible to adjust according to customer’s needs，Free welding - all components connected with fasteners and Long service life.

PV Combiner Box 

In the intelligent combiner box, in addition to the functions and performance of the general combiner box, a temperature sensor is added in the combiner box, and multiple monitoring points are set. To protect the combiner box from being burned.
