Utilizing the photovoltaic effect with solar panels, solar electric power generation transfers solar energy to direct-current energy and stores it. Solar electric power generation is widely applied in communications, microwave, optical fiber cable transmission, railway communications, highway signals, lighting, landscape, mobile electrical equipment, etc. Thanks to its feature of no pollution to the environment, it becomes increasingly the energy that attracts people’s attention. The basic principle of solar power station is shown in the figure below：

Photovoltaic controller is the key component in photovoltaic electric power generation system. The performance of the photovoltaic controller has direct impact on the life of the system, especially that of the storage battery pack. Under any circumstance, overcharge or overdischarge of the storage battery will reduce the service life of the storage battery. Our company has years of design experience in the production of photovoltaic controller and a large number of customers. The products have stable quality, high reliability and adaptation to severe dicky places.
