As long as there is sunlight, it can be installed and used. The off-grid solar system is widely used because it is not restricted by region. The off-grid solar power systems must be equipped with a battery, while the on-grid solar system does not have a storage battery and other storage devices. And when solar power can't generate enough power for home appliances, it's automatically replenished from the grid. Solar power generation is directly inverted into the parallel voltage required by the national grid and is preferentially used by families. On-grid solar systems, namely solar power generation, household power grid, and public power grid, are linked together. When it is needed to use, the direct current in the battery flows through the inverter and is converted to alternating current. The electricity generated by the solar panel flows directly into the battery and is stored. The photovoltaic array converts solar energy into electric energy when there is light, and supplies power to the load through the solar charge and discharge controller.ĭifference Between On-Grid and Off-Grid Solar SystemĪn off-grid solar system, also known as an independent solar power generation system, is a system that does not rely on the power grid and operates independently. The on-grid solar power system is generally composed of photovoltaic array composed of solar cell modules, solar charge and discharge controller, grid-connected inverter, DC load and AC load.
