The energy storage inverter is a converter that. converts DC power (battery, storage battery) into constant frequency and constant voltage or frequency modulation and voltage modulation AC (generally 220V, 50Hz sine wave). The energy storage inverter is mainly used in the energy storage link of the grid connection, which can realize the bidirectional conversion and flow of electric energy according to the needs, and is an important part of the energy storage solution in various scenarios. Energy storage inverters mainly include centralized inverters, string inverters, distributed inverters, and micro-inverters.
Breaking through the limitations of weather changes can reduce the impact of weather conditions on the stability of power generation and improve the stability and quality of the power grid.
It has higher power consumption efficiency, can provide users with more stable and lasting power, and avoid inconvenience and trouble caused by power system failure.
It has high stability, can realize the two-way conversion of DC and AC, and can provide a strong guarantee for power consumption when the power is cut off.
Higher self-use ratio.
When the power grid fails or the grid is unstable, it can automatically switch to the battery-powered mode, and the load can continue to be used.
The effect of two-way energy storage - photovoltaics can charge the battery, and the same power grid can also charge the battery; in this way, the battery can be used to adjust the peak-valley electricity price difference or be used as a backup power source.
It can also be used under pure off-grid conditions to drive loads with a certain power.
