Auto Generator Start – Onboard Generators

This interface box connects Victron devices to onboard generators. It interprets start/stop signals from Victron systems and converts them using four adjustable relays into signals the generator recognizes. By default, it sends negative signals; positive signal versions are available. Key Features: • No power cycling needed after unexpected shutdown • User-friendly operation • Weather-resistant IP65 enclosure • Compatible with 12v, 24v, and 48v systems • Works with Onan, NPS, RVMP, and marine generators Requirements: Victron Cerbo GX with SmartShunt or BMV-712; generator with two signal wires and negative wire. Compatibility Notes: Negative signal works across all voltages. Positive signal typically 12vdc only. Onan QD3200 incompatible. RVMP and marine require modifications.
