Description

Intelligent building self-generation system

technical field

The utility model belongs to a solar power generation technology, in particular to a solar self-power generation system that is built in a building for self-use by residents and transmits excess electric energy to the outside through a power grid.

Background technique

Photovoltaic power generation is a technology that uses the photovoltaic effect surface of the semiconductor interface to directly convert light energy into electrical energy. The key element of this technology is the solar cell. The solar cells are packaged and protected after being connected in series to form a large-area solar cell module, and then cooperate with power controllers and other components to form a photovoltaic power generation device. The advantage of photovoltaic power generation is that it is less subject to geographical restrictions, because the sun shines on the earth; household power generation systems generally consist of photovoltaic arrays composed of solar cell components, solar charge and discharge controllers, battery packs, off-grid inverters, DC loads and AC load etc. If the output power is AC 220V or 110V, an inverter is also required. The photovoltaic square array converts solar energy into electrical energy under the condition of light, supplies power to the load through the solar charge and discharge controller, and charges the battery pack at the same time; when there is no light, the battery pack supplies power to the DC load through the solar charge and discharge controller. At the same time, the battery should directly supply power to the independent inverter, which will be converted into AC power through the independent inverter to supply power to the AC load.
