Photovoltaic + Energy Storage Off-grid Microgrid System
1) Customer Pain Points: Aiming to leverage the abundant local solar energy resources.
2) Solution: Implemented a “5 kWp Photovoltaic + 30 kWh Energy Storage” off-grid power supply system.

3) Operating Mode: The system operates in a fully off-grid mode. During daytime, photovoltaic power generation satisfies real-time load demands and stores surplus electricity in large-capacity energy storage batteries. At night or on overcast days, all electricity consumption is entirely supplied by the energy storage batteries. The system’s design capacity comprehensively accounts for the user’s daily electricity consumption and required backup duration, ensuring continuous power supply even during multiple consecutive days of poor weather.
4) Implementation Results: The system demonstrates stable operation with straightforward maintenance, achieving power self-sufficiency. Electricity costs are nearly eliminated after the initial investment, providing a cost-effective and practical solution for power supply difficulties in off-grid areas.
