Cerbo Gx or CCGX Auto Gen Start for Onan QG 4000

I have ordered a 2021 Winnebago Minnie Winnie 26T and it comes with the Onan QG 4000. It does have a remote switch in the coach to turn on the generator.


I would like a wiring diagram to both the CCGX and to the new Cerbo GX. I am looking at the Cerbo/ Touch GX combination as an alternative to the CCGX. Ultimately I will go the direction of which one serves my purposes better and works easier with the Onan Auto Gen Start.


I will be using all Victron components:

150/100 MPPT VE. Can Solar Charger

10x95 Zamp Solar Panels

4x200ah Smart Lithium Batteries

Victron Battery Monitor

Either the 12/3000 Multi-plus Inverter charger or the 12/5000 Quatro


I am also looking at adding the SeaLevel II tank monitoring system. (if I go the Cerbo GX route I would like to use in in connection to this system using the NMEA2k connection)


This would all be connected to either the CCGX or the Cerbo/Touch GX.


Please advise on the wiring diagram for both and what parts are necessary to make this work. I will want to have the generator start and stop based on the state of charge parameters I set as well as time blocks during quite hours.


Thank you for anyone who can help me sort this all out.

What kind of switch is it? Just on/off?

Than you can use CCGX or Cerbo relais paralel to the switch.

Yes, it is just an on/off switch with hour meter.

which means there is a starter logic in the generator, just use the relais of the GX device on the same wires or connections as the switch.

What relays do I need to buy specifically?

Use a Cerbo gx

the ccgx is beginning to come to the end as we know it, lagging in processing power and the cerbo is the future.

If you don’t need a display all the time just use a Venus, and you can use your tablet to see what’s going on when your interested.
