Application of hybrid on off grid storage inverter in photovoltaic energy storage system

In recent years, with the decline of photovoltaic subsidies in various countries and the decline of investment income of pure photovoltaic projects, photovoltaic energy storage system has become the choice of more and more people.

According to different applications, photovoltaic energy storage and power generation systems can be divided into four types.

• on off grid energy storage system

• off grid power generation system

• grid connected energy storage system

• multi energy hybrid microgrid system

The on off grid energy storage system is widely used in applications such as photovoltaic self use, no surplus on grid, self use electricity price is much more expensive than on grid electricity price, and peak electricity price is much more expensive than trough electricity price

The photovoltaic on off grid energy storage system is composed of photovoltaic array, hybrid on off grid energy storage inverter, battery pack, load, power grid, etc. The photovoltaic array converts solar energy into electric energy when there is light, and supplies power to the load through the on off grid energy storage inverter to charge the battery pack; When there is no light, the AC load is powered by the battery and the power grid.

Compared with grid connected power generation system, the cost of on off grid integrated system has increased, but its application range is wider and its function is more powerful.
