A photovoltaic switch is an electrical component used to connect or disconnect a photovoltaic installation from an electrical network. Its main purpose is to ensure that the solar cells do not overload or overheat, which can cause damage to the installation and pose a safety risk.
Photovoltaic switches are usually used as a safety measure to disconnect the solar cells from the grid when there is a power outage or fault in the grid. This reduces the risk of electrical accidents and damage to the installation. The switch can also be used to switch off the PV system during maintenance or repairs.
Solar switches come in different sizes and models and can be manual or automatic. They may also have various functions such as overcurrent and overvoltage protection to further ensure the correct and safe operation of the installation.
