Growatt ATS-T three-phase contactor SPH3-4.6kW three-phase automatic relay switch for Growatt SPH series storage inverters

The Growatt 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.
