An off-grid micro-grid is a power supply mode that can be built and operated independently, without an external grid. It can ensure the balance and stability of power generation and supply.
An off-grid micro-grid converts renewable energy (e.g., solar energy and wind energy) into electricity. When renewable energy is abundant, not only the converted electricity can be directly supplied to the load, but also the surplus electricity can be stored with energy storage devices. When renewable energy is insufficient, the stored electricity can be used for power supply. The use of renewable energy can be maximized to reduce the use of fossil energy.
