The Growatt ATS-S is a single-phase transfer switch and controls the changeover of the switching device both when connected to the power grid and in stand-alone operation in order to provide power to the EPS load. It is used with Growatt inverters from the SPH and SPA series. The ATS-S can automatically switch to stand-alone operation in the event of a power failure and thus supply everything else with power to guarantee smooth operation. Its natural cooling concept is used to prevent overheating.
