Off grid solar system, also known as stand-alone solar systems, generate electricity independently rather than relying on the grid. The off grid solar system mainly consists of solar panels, batteries, solar controllers, inverters and other components. The DC electricity emitted by the solar panel directly flows into the battery and is stored. When the AC loads need to be powered, the DC power in the battery is converted by the inverter into AC output. This is a repeated cycle of charge and discharge. This system is not subject to geographical influences and restrictions. Off grid solar system can be installed and used wherever the sun shines, so the off grid solar system is very suitable for use in homes, areas without power grids, fishing boats, outdoor breeding bases, etc. In addition, it can also be used in areas with frequent power outages emergency power generation equipment.
