The conventional d.c. isolation system installed on Australian rooftop solar panels fails to provide complete and safe isolation.

The Solar Safety ShutOFF is different in that it tackles the problem of DC isolation at the source (i.e. before the panels combine to lethal d.c voltages). The Solar Safety ShutOFF is capable of simultaneously isolating solar panels, stopping the combining of panel voltages and provides rapid shutdown to zero volts dc in less than 5 milliseconds. Shutdown can be performed manually at the switchboard, remotely by disconnecting the external AC power, or automatically if heat is detected from an internal or external fire.
