An auto-start generator can be integrated with the Enphase
Storage system without the need for any external ATS.

the IQ System Controller 2 Generator input terminal for power
monitoring when the generatoris running.
2. Use Enphase Installer Toolkit mobile application to commission
and program IQ System Controller 2 to control the generator.
For 2-wire autostart generators, wire the
Generator I/O port in IQ System Controller 2
to the 2-wire remote start terminals of the
generator.
Wire the primary of a 120V/12V power
supply to the backup loads panel. Connect
the secondary to the Generator auxiliary
contact relay on the Enpower R2. Wire
the other end of the relay to the coil of the
Normally Close contactor. Connect the
contactor to 240V from the backup loads
panel for utility sensing. Wire the other end
