Generator Control
Generac Guardian 2-Wire Start Conversion Kit
Convert compatible Generac Guardian generators for 2-wire start/stop control from a solar inverter, battery monitor, relay, or other external controller.
This kit is commonly used with solar, battery backup, and off-grid systems where the generator needs to start automatically based on battery conditions rather than waiting for AC power to fail.
Key Details
What to know before you buy
- Connectorized control wires install into unused generator-controller connector positions.
- A typical installation uses an external relay or switch between J1 Pin 18 and J2 Pin 10.
- Closing the external contact commands the generator to run; opening the contact commands it to stop.
- The generator setup menu must be configured for 2-wire start, with the generator switch left in AUTO.
Before Ordering
Confirm the product fits your application.
Generac has used different controllers and configurations across generator models and production years. Confirm the generator model, serial number, and controller type before ordering.
