Product notes

Designed for 220–230V single-phase AC systems.
The backup power source must be available before transfer.
The Wi-Fi module is powered by Source A. Remote app control becomes unavailable when Source A loses power.
Automatic transfer functionality can continue independently of remote app availability.
The app's selected source status does not necessarily reflect the actual source currently supplying power.
Does not automatically start a generator without a separate compatible generator-start system.
The specified transfer time does not guarantee uninterrupted operation of sensitive electronic equipment.
Not a substitute for properly rated circuit breakers or required electrical protection devices.
Professional installation is required.
