Generator changeover switches, wired in safely
Plugging a generator into a wall socket with a double-ended lead is dangerous: it can back-feed the grid and electrocute someone working on the line. A changeover switch connects the generator properly and keeps the grid and generator apart.
Worth a call if
- You already own a generator
- Your business cannot stop during outages
- You run an off-grid or farm system
Manual or automatic
A manual changeover switch is simple and cheap: you start the generator and flip the switch. An automatic transfer switch starts the generator and switches over by itself when the grid fails, which suits businesses and anyone often away from home.
Generators and solar together
With a hybrid inverter, the generator can be wired to the inverter’s generator input, so it charges the batteries and only runs when the battery is low. That saves fuel and engine hours.
