Solar storage and charging project for a tobacco company

Project functions:

1. Make full use of lighting resources to achieve green electricity consumption and ensure electricity consumption for charging stations, lighting, etc.
2. Ensuring the safe operation of photovoltaic systems, energy storage systems, charging stations and other devices;
3. Use energy storage to reduce peak loads and fill load valleys, thus reducing electricity costs.
4. Use energy storage to absorb new energy and increase the photovoltaic absorption rate.

Site information:

1. The system is based on a 0.4 kV AC busbar and is equipped with Ankerui meters.
2. After the two photovoltaic inverters (20 kW and 80 kW) have been combined, they are connected to the 0.4 kV grid via the grid-connected cabinet, which is equipped with a meter and an anti-islanding device.
3. Energy storage system 75 kW/150 kWh, directly connected to 0.4 kV energy storage circuit and equipped with Ankerui meter;
4. AC charging stations with a total of 13 units and 7 kW per day are installed under the parking garage and are equipped with Ankerui meters.
5. Parking garages one and two are each equipped with lighting modules.
