Off-grid energy storage: 1. The main function is to convert the DC power generated by solar panels into AC power for load use. 2. Usually equipped with energy storage batteries to store excess power and release it when needed. 3. Independent operation, not dependent on the power grid, suitable for remote areas or areas without grid access. Application scenarios: 1. Mainly used in remote mountainous areas, deserts, islands and other areas without grid access or unstable grid. 2. Suitable for families, small commercial projects or occasions requiring independent power supply.   Hybrid energy storage: 1. It has both off-grid and grid-connected functions. It can convert the DC power generated by solar panels into AC power for load use, and can also be connected to the grid to achieve two-way flow of power. 2. When the power supply of the grid is normal, it can obtain power from the grid to supplement the shortage of solar power generation; when the power grid is out of power, it can switch to off-grid mode to provide power for the load. 3. It has efficient inverter capability and intelligent charging function, which can automatically adjust the charging parameters according to the battery status to extend the battery life. Application scenarios: 1. Applicable to places with grid access and where solar power generation is used to reduce electricity bills or achieve energy self-sufficiency. 2. Applicable to various occasions such as homes, enterprises, and public facilities, especially in areas where grid power supply is unstable or where energy efficiency is desired.
