Ⅰ.Photovoltaic off-grid power generation system
The photovoltaic off-grid power generation system operates independently without relying on the main power supply. It is used in remote mountain areas, areas without electricity, islands, communication base stations, and street lights.
The system is composed of photovoltaic array, solar controller, inverter, battery pack, load, etc. The photovoltaic array converts solar energy into electric energy when there is light, and powers the load through the integrated solar control inverter, while charging the battery pack; when there is no light, the battery powers the AC load through the inverter.
Ⅱ.Photovoltaic grid-connected energy storage system
Grid-connected energy storage photovoltaic power generation system can store excess power generation and increase the proportion of self-generation and self-use. It is used for photovoltaic self-generation and self-use cannot be connected to the grid. The price of self-use electricity is much more expensive than the price of on-grid electricity. The peak electricity price is more expensive than the wave price. A lot more expensive and other applications.
The system is composed of a photovoltaic array composed of solar cell components, solar control, battery pack, grid-connected inverter, current detection device, load, etc. When the solar power is less than the load power, the system is powered by the solar energy and the grid together. When the solar power is greater than the load power, part of the solar power supplies power to the load, and part of it is stored by the controller.
