Looking for anyone that has installed, or has knowledge about, an auto generator start off of a Victron MultiPlus2 (actually the CerboGX), and can share the details with me.

I recently replaced the original MSW Magnum inverter with the Victron MP2, CerboGX and the touch screen monitor.

Thanks Vince for commenting and the links.

I am familiar with the Victron AGS info. It's a helpful document.

I'm hoping to find someone that has actually done the upgrade.

I have. I posted about it here.

Thanks for replying. Glad to see someone here has done it. I did see that post a few weeks ago. That's the direction I was headed.

What kind of generator do you have? And what AGS functions are you looking for?

A few years ago I installed an Onan EC30 AGS. It was a bit of work to install, although if you have the Magnum AGS it likely has most of the same wires needed. The user interface to it is awkward to use. I was able to connect the relay from my BMV712, so I can start and stop based on voltages or SOC. I also have one of my thermostats tied in, as well as various other connections.

Magnum now makes a wireless AGS that has a more modern phone interface. It's not as integrated into the electrical system, but is easy to install and looks like a nice product.

I recently upgraded to a MultiplusII, and since my AGS wasn't tied to my inverter it didn't require any changes for my AGS function.

My understanding of the Magnum wireless AGS is that it still requires you to be at the coach to access the unit, as it uses Bluetooth (?). The benefit of the Victron Cerbo GX AGS is that it is internet-based and can be programmed from anywhere, and/or the generator can be manually started from anywhere. I'm in Phoenix, and I've been using this ability when I'm going to the motorhome to work on it. I start the generator an hour or so before I leave home, and the coach is cooled down when I arrive. Haven't used it on a road trip yet, but there will be more great benefits on the road.

I have a onan QD. My old magnum had the AGS remote box, which can be used with the CerboGX, as I understand it.

With this set up, as long as you have WiFi , you can control everything going through the Cerbo from anywhere. And Bluetooth if you prefer that.

PVCambell did a nice write up that he referenced a little earlier. All the generators makes and models are not connected the same, so you need to look at specific equipment to get it right.

I didn't look at your previous post very closely at first. Looks like a very nice setup.
