Overseas 750KW/1505KWh Solar-Storage System Technical Solution

This technical solution details a 750KW/1505KWh solar-storage system for an overseas industrial park with two transformers (500kVA and 1000kVA). The park integrates 1138KWp of PV, energy storage, and a diesel generator to ensure reliable power. The system uses PV-storage integrated machines to handle outages: during grid failure, PV and storage supply loads; when grid returns, it powers loads via bypass; if all fail, diesel takes over. The 500kVA transformer gets a 500KW/1075KWh system, while the 1000kVA gets 750KW/1505KWh, both using standard containerized products for 400V low-voltage grid connection. Key components include battery stacks with cells and modules, BMS for monitoring and safety, air conditioning, fire protection, combustible gas detection, PCS for power conversion, and an energy management system for data acquisition, anti-reverse power flow, SOC maintenance, peak shaving, valley filling, and microgrid economic operation. The solution ensures stable, efficient energy supply for the park.
