Today, photovoltaic off-grid power station is very hot, in the home installation of a solar photovoltaic power station has become the pursuit of many families! Solar photovoltaic power generation is based on the principle of photovoltaic effect, solar photovoltaic cells are used to convert solar radiation energy directly into electric energy. Household solar photovoltaic power generation system can be made into off-grid system. It can also be made into a grid-connected system.
Photovoltaic off-grid power station is suitable for areas where there is no grid-connected or unstable grid-connected power. Photovoltaic off-grid power station has more batteries than grid-connected system, and its system is usually composed of solar modules, controllers and inverters. The battery set and the support system are made for their own use. They produce DC power that can be stored directly through the day or stored in the battery for the purpose of providing power at night or on cloudy or rainy days.
Distributed grid-connected photovoltaic power station, its system is composed of photovoltaic square array, controller, grid-connected inverter, bidirectional meter and so on. Therefore, two-way meter is needed to measure the electricity generation and the power on the Internet.
Household solar photovoltaic power generation system has a service life of more than 25 years, as long as there is a sun can be used. Build a 2-3KW power station system, about 1500-2700 degrees per year, part of the electricity can be used by themselves. Unusable electricity can also be sold to the state grid. If you want to build a set, you can wait for income. Photovoltaic off-grid power station is an independent solution. Because it can be installed in most places and easy to maintain locally. When the power generated by the solar power generation system can not meet the needs of the equipment, the solar power generation system automatically switches to the urban power; When solar power is restored, solar power systems switch to solar-powered electricity. They are a reliable, clean and cost-effective alternative to diesel generators.
