Introduction

The Auto Transfer Transformer (ATS-US) controls the switch of the contactors to provide power to the critical load stated as EPS Emergency
Power Supply load in both grid-tied and off-grid conditions. There is a contactor in ATS-US to provide user a simple connection. ATS-US is
operating with PCS inverter for the purpose of providing the split phase power when grid accidentally or unexpectedly goes off. This
approach allows the home critical contunously to be supplied.

default to connect with Grid power.If Grid is lost, EPS Load will
turn the switch to EPS output of hybrid inverter. And there is a
transformer in ATS-US, it can transform 240V to 120/240V split
phase to provide the power to critical load.
