Putian parking lot microgrid project is a photovoltaic and battery energy storage integrated microgrid project located in Shenzhen, China. The project can operate in both the interconnected mode and islanding mode.

Project overview

CYG provided equipment for the Minle photovoltaic microgrid is briefly listed below:

1. One photovoltaic power station which total generation capacity is 47.7kWp.
2. One set of energy storage system which storage capacity is 200kWh.
3. One set of control system containing the whole set of microgrid control system and control device.
4. The local load includes the local charging pile group (21 45kW DC charging pile and 44 40kW AC charging pile) and office electricity supply.

The Putian Microgrid has operated successfully since 2017. Its high stability has win the comment of the customers. The Longhua district has long suffered from the electricity shortage. In the summer of 2017, the district has cut down part of its zones, which the Putian parking lot is located in. And the microgrid system keep on supplying the electricity power to the electric cars until the batter totally ran up.

Besides the high stability, Putian microgrid has also created enormous economic value to the customers.
