ECOFLOW Automatic Transfer Switch makes power outages almost invisible by automatically transferring your home from grid electricity to backup battery power when the lights go out. It detects a blackout and switches over in a split second, so essential circuits stay powered without you needing to flip any switches. Once the grid returns the switch reverts back automatically to restore normal supply. It connects your home panel to a compatible EcoFlow portable power station like DELTA Pro, enabling safe and seamless whole-home or partial-home backup. The switch helps prevent dangerous back-feeding into the main grid while giving you continuous power for lights appliances or fridge. It is ideal for homes in areas with frequent power cuts or for anyone wanting reliable standby power without manual hassle.
