Photovoltaic off-grid power generation system is no grid-connection or interconnection power unstable region, pv off-grid system usually consists of solar module, controller, inverter, battery and support system. They produce dc power can be directly through the day or store
solar off-grid power generation system is suitable for no grid-connection or interconnection power unstable region. Usually by solar energy photovoltaic off-grid system module, controller, inverter, battery and support system. Produced by their DC electric energy can be used directly in the daytime or stored in the battery pack, for in the evening or cloudy or rainy days. Off-grid system is an independent solution, because it can be installed in most places, and easy to local maintenance. They are reliable, clean and the economic and efficient solution, can replace diesel generators. Micro grid system of micro grid system is an independent control unit. Solar photovoltaic power generation can be various types of power equipment, energy storage devices, load and control device integration together, to generate electricity or heat supply to users. It can meet the needs of different users, the capacity of the system from a few kilowatts to hundreds of kilowatts range and even a few megawatts. The system can support a variety of load, such as lighting, desk fan, color TV, desktop computer, sound, etc. For example, according to different system, the refrigerator can continue to use. The controller is integrated with solar energy charging circuit, inverter circuit and microprocessor, in order to protect the battery from over charging and discharging, protect the controller from short-circuit or reverse connection of solar panels or batteries, and warning is given due to the power shortage. Residential housing off-grid system off-grid system can be installed on the roof or ground. According to the survey of the international energy agency, 14. 5. 6 billion people live without electric power environment, 83% of whom live in rural areas, that is why most off-grid system used in the rural areas. It has low cost, clean, renewable, reliable, convenient and easy to install and maintain, etc. One-time investment alternative power supply more than 25 years. Off-grid communication base station system with the wide use of telecommunications in the modern society and the importance of telecommunications infrastructure and establish between the cities. Photovoltaic power generation in order to find a suitable off-grid power supply, and minimize the energy cost and environmental impact, the telecom industry is eager to find a solution, to replace the ordinary power photovoltaic industry. Solar off-grid system provides a way to meet the demand of telecommunications solutions. Off-grid solar communication base station base station installation is simple, do not take up too much land resources, can immediately to generate electricity. Offline communication base station system has reliable power resources and to store enough energy resources used in an emergency. At the same time, it also has a clean, renewable, easy maintenance, etc. And at low cost input power supply for 25 years. Solar street lamps system of our solar street light system using efficient components to provide power supply. During the day, the component to recharge the battery. In the evening, batteries provide enough power for light bulbs. It has a lot of control mode, such as time control, lighting control, remote control, etc. You don't need to control it, also do not need complex and expensive wiring and plumbing. In addition, the solar street lamps use the low voltage DC power supply, more safe and reliable, which can be widely applied in the crisscross streets, rural roads, etc.
