If you lose power during a cyclone or storm, then turn off your mains switch in your fuse box and use your generator for auxiliary power. It’s important to turn off your mains switch first because when the power comes back on, you can get a power surge, which may damage any electrical items.
Turn off your electrical items as well and shut down your solar panels before you switch on your generator. Once the generator is up and running, turn on your electrical items slowly. If you do it too quick, then you can kill the generator.
