The Growatt Backup Box ATS-T (Auto Transfer Switch Three Phase) controls the switching of the contactors to provide power to the EPS load in both grid-tied and off-grid conditions. The ATS-T integrates a contactor to provide users with a simple connection. It is used with Growatt Hybrid inverter and AC coupled inverter (single phase). Configured with ATS-T, when the power outage, ATS-T can automatically switch to Off-Grid state, it can continue to supply power to the EPS load, the load can continue to run.
