The difference between energy storage power plants and PV power plants is that: distributed PV power plants are connected to the grid nearby, and can use excess power for themselves when generating online; while energy storage power plants require the addition of energy storage batteries. The power of the storage battery can be released at night when the PV power plant is not generating electricity, in order to achieve the effect of self-generation and multiple use.
Energy storage power station not only need to add storage batteries, while the grid inverter also needs to be replaced with a parallel inverter to use.
Then the storage power plant in the end the battery needs how big? How much is needed?
The size of the energy storage capacity in the energy storage power plant is based on the power of the power equipment to use the time proportional to become. If you do not care about the use of time, how long can be used is how long. Energy storage battery with how much is the capacity can be, but the voltage should match.
If you want the facility appliances to meet a certain use time, are required to separately calculate the energy storage capacity. Energy storage more electricity can not be used to waste costs, less energy storage can not meet the needs of self-use. All energy storage systems are basically not unified, and can only be calculated individually by using power and time combined with local light resources.
