My generator doesn't equip with ATS (automatic transfer switch). The purpose of the dual power automatic transfer switch is simply to use as common or backup. When the common power suddenly fails or the power is cut off, the dual power switch is automatically put into the standby power supply, (The backup power supply can also be powered by the generator under small load.) to keep the device still running. ATS can detect the mains failure signal. When the mains fails, it can give a control signal to the self-starting end of the generator set in time, so that the unit can start itself and prepare for power supply. If you want to connect your generator to the inverter, you really need to inquire professional engineer since it is electrical equipment. Your genset uses the same controller SmartGen controller with mine.
