Multi-functional PCS is a key device to control the bidirectional energy transfer between DC energy storage battery and AC power grid. The equipment can switch charging and discharging working modes according to the power grid state or program setting. However, when the power grid fails and the microgrid is isolated, it can play an emergency independent inversion role in the microgrid, adjust the voltage and frequency of the microgrid, and ensure the stability of power supply for key loads. The multifunctional energy storage converter has the functions of peak cut, stabilizing the fluctuation of new energy output, providing emergency power supply, etc. It is an important component of smart grid construction and microgrid operation.
The multifunctional PCS can be deeply customized according to customer requirements. Access to pv, add pv control module, STS and off-grid switch, boost transformer, etc.
PV control module: the maximum power point tracking technology is used to extract the maximum power from the PV array to ensure the maximum utilization rate of solar energy. At the same time, a DC/DC module is built in, which can adjust the PV DC voltage so that it can be connected in parallel with the battery to charge the battery or output on the AC side through inversion.
STS（on/off Grid Swich）With modular design, it can realize fast switching in 10ms of off-grid state, can protect important loads such as servers from power failure, and realize automatic operation of energy storage power station without duty.
It has bi-directional converter to charge and discharge the energy storage battery.
