A high startup surge overloads the circuit when the compressor kicks on.
Generators struggle with high initial loads from AC units and pumps.

A high startup surge overloads the circuit. A soft start device reduces that surge so the circuit isn't overloaded.
Generators struggle with high initial loads. A soft start device lowers that startup demand so your generator can keep up.
No. The unit works out of the box with a generator. Set the app's power settings closest to your setup. A bonding plug isn't required, but it is recommended.
Surge protection is included on our 20 and 30 amp models. On the 50 amp it is optional.
The green light on both plugs turns on when power is passing through. Turn on the appliance and it should start.
