What role do storage batteries play in a solar PV system?

A complete solar photovoltaic system usually includes the following parts: solar panels, inverters, storage batteries, monitoring systems, mounting components, cables ...... So what role does the storage battery play in solar PV power generation? What role do storage batteries play in solar PV power generation?

The Wanhos wall-mounted lithium storage battery is used as an example to introduce the role of storage batteries.

Balancing energy supply and demand: lithium storage batteries can store excess power, and then release the power when the user needs to use electricity, between a storage and release, skillfully balancing the power supply and demand between the time contradiction; solar photovoltaic panels in cloudy and rainy weather and at night, it will greatly reduce the efficiency of power generation, then the storage batteries can be stored before the release of electricity for use when power generation is not possible.

Emergency standby: In some underdeveloped areas of the power grid, power outages are often encountered during the peak period, if you are in the office at this time, then the data in the computer information is very likely to be lost, and if it is in the hot summer weather power outage, you have to put up with the high temperature of the torture. Energy storage batteries can play the role of backup batteries to provide stable power to avoid unnecessary losses.

Maintain system stability: photovoltaic modules in the power generation output process, there will be fluctuations in power, and the storage battery is a "peacemaker", it can buffer these unstable power, so that the sun's energy in the output of a more stable, which is conducive to improving the stability of the photovoltaic system and service life.

There are many types of storage batteries on the market today, but to summarize, the role of the storage battery is to make it more convenient for users to use solar energy.
