The main function of the energy storage inverter is to handle the bidirectional transmission of energy between the AC grid and the energy storage battery.
It is also a bidirectional converter, which can be adapted to operate with various DC energy storage units, such as an ultracapacitor group.
Battery packs, flywheel batteries, etc., can not only quickly and effectively manage fluctuations in random power or tidal currents of distributed generation systems, improving a grid's ability to accept large-scale renewable energy generation (wind, photovoltaic), but can also accept scheduling instructions. This enables the absorbing and, where required, supplementing of the ‘peaks and valleys’ of a grid’s energy level, enhancing its quality and economic benefits.
In the event of a grid failure or power outage, there is also an independent network power supply function to improve the security of the load.
