What is a solar isolator switch?
A solar isolator switch is a safety device that manually disconnects the direct current (DC) electricity from the solar PV system.The isolator switches are usually located close to the solar panels on the roof and close to the DC end of the inverter, which means the panels can be disconnected both on the ground and on the roof.
