What You Need to Know About Solar Isolator Switches
A solar isolator switch is a safety device that manually disconnects the direct current (DC) electricity from the solar PV system. It is typically located close to the solar panels on the roof and near the DC end of the inverter, which means the panels can be safely disconnected both on the ground and on the roof. The purpose of the solar ...

Disconnection Points Vs DC Isolators: A Solar Inspector''s Experience
The idea is that in the event of a fire, the solar panel arrays on your roof could be safely switched off by anyone on the roof using the rooftop isolator – so they could be confident they would not be electrocuted as they battled the flames. DC isolators became mandated nationwide via the Australian Standard for solar installations: AS5033.
