New single-phase automatic transfer switch to simplify energy management in your home. With its simple installation, it ensures continuous and safe electrical supply. A practical and efficient solution for automating the electrical system. This switch is designed for users with a power station (batteries), automatically switching from grid power to battery power when the grid power fails. I mistakenly purchased a single-phase unit, then bought a three-phase one instead. It never worked. It is brand new.
