Mainly refers to the photovoltaic power generation system that households themselves need to power, consisting of solar panels, controllers, inverters, and lithium battery packs. For example, HaiLei's new off grid energy storage system can store electricity when there is sufficient sunlight, or directly supply electricity to the household's load. When there is no sunlight, the load is directly powered by the energy storage system.

Independent photovoltaic system

It refers to a photovoltaic power generation system that provides power to regional users. In some non electrified villages, towns, islands, etc. with good lighting conditions, it is suitable to establish independent photovoltaic power stations. The capacity of independent photovoltaic power stations is generally large, and the independent photovoltaic system consists of solar panel arrays, lithium battery packs, converters and energy managers, distribution and Electric power transmission to form a regional grid. It is recommended to consider the new off grid energy storage system developed by HaiLei, which has low power consumption and high stability.

2、 Grid connected photovoltaic system

The grid connected photovoltaic system is to convert the direct current generated by solar power generation into the alternating current meeting the requirements of the municipal power grid through the Grid-tie inverter, and then directly connect it to the public grid. It is one of the development paths of solar photovoltaic technology. Of course, grid connected photovoltaic systems should not consider special fault states, such as islanding, as these faults will have some adverse effects and must be protected.
