The GRUDGE Smart box is an Australian made automatic transfer switch developed by GRUDGE!
The GRUDGE Smart Box can be plugged into many models of our generators (petrol and diesel) and then plugged directly into your house.*
The Smart Box monitors the mains power supply, When the mains fail it starts the generator automatically and restores power to your house. When the mains resumes, the generator is switched off and goes back into standby mode waiting for the next power outage.
There are 3 models available including a Smart Box for solar/battery systems, mains failure monitoring, and for both solar and mains monitoring.
*PLEASE NOTE: The GRUDGE Smart Box should be installed by a qualified electrician.
