Microgrid Solutions and Cases


A microgrid system is a distribution system that can achieve self-control, protection and management according to predetermined objectives.

It can operate interconnected with the external grid to form a grid-connected microgrid, and can also operate in isolation to form an islanded microgrid.

Energy storage systems are an indispensable unit in the microgrid to achieve internal power balance, provide stable power to the load, and improve power supply reliability; realize seamless switching between grid-connected and islanded modes.

Mainly Applied To

1. Islanded microgrid areas without electricity access like islands;

2. Grid-connected microgrid scenarios with complementary multiple energy sources and self-generation for self-consumption.


1. Highly efficient and flexible, suitable for various renewable energy generation systems;
2. Modular design, flexible configuration;
3. Wide power supply radius, easy to expand, suitable for long-distance transmission;
4. Seamless switching function for microgrids;
5. Supports grid-connected limited, microgrid priority and parallel operation modes;
6. PV and energy storage decoupled design, simple control.
