Professional quality! Lack of Victron documentation supporting integration with this popular generator very frustrating so your presentation was a welcome source of perspective. That said I purchased my Color Control GX just before the CERBO GX came out. Can you comment re a similar relay integration between my Onan 3.6 KY and the Color Control GX single relay?

Does the color control relay have the same type of relay ? With normally open, common, normally closed? Do you have a multiplus or Quattro? Those have relays in them as well that can all be used the same way

Here's another option using the 2 relays in the Multi. Switch power wire bridged to the common of K1 & K2. Start wire to K1 n/o, stop wire to K2 n/o Then my assistants are set as follows; 1 close K1 n/o when voltage = 24.2v 2 open K1 n/o 5 seconds after 220v detected 3 close K2 n/o 3600 seconds (1 hour) after absorption phase starts. 4 open K2 n/o 5 seconds after 220v ends. This will work for any genset that uses a straightforward momentary hold-to-start, hold-to-stop switch. If you only have 1 relay, wire the Victron n/c to a 5 pin automotive relay. The center pin is n/c, so it will be open when power (from the Victron n/c) is applied. Wire this center pin to your stop switch. Then change the above assistants to: 3 open k1 n/c 3600 seconds after absorption 4 close k1 n/c 5 seconds after 220v ends The down side of this is that the automotive relay will be permanently energised drawing a small amount of power. If the the relay fails, not a major problem because it will only result in your genset not starting (because the stop button is activated)

Great Video. I just bench tested 4 relays will be installing shortly: I used the same relays but used 4 to create a Stop/prime, Start and Stop. To make sure the generator was off before starting. I could see the gen being on with breakers tripped etc. or I forgot to put flip them ON, this would make sure it's off before starting and give a prime function if needed. 1st relay(1r) was single shot to stop F, 2r is a timer relay H, 3r is start relay and 4r is stop F. What happens the start in signal will use relays 1-3 (stops gen/prime F, Delay H, Start F ) and the stop in signal uses 4r(stop F). 1r #18 and 4r #18 tied to the out single to stop gen. 2r #18 is tied to 3r A2 so 3r is not on until 2r delay is done. Note: set I the delay of 2r is longer than time of 1r. Will be hooking this up this weekend for actual run test with generator and cerbo gx.

Thank you Lester. I appreciate it. whynotrv@yahoo.com for nothing crazy specific but if you have a question, others probably have the same question. For start power I assume you are talking about the start signal wire to actually start the generator. I went over it in this video. Depending on your set up and what is pre-existing in your RV, you might be able to control it from a panel inside. If not, you can add a switch. Review the video again and you’ll see where I went over it.

Watched the video a few more times noting that -it is for a cerbo gx - cerbo gx relay output points are for NO and NC and does not include COM -a ground instead of COM is used to start/stop the gen in this example while my remote switch uses a COM wire Since I would like to use my color control GX (CCGX) with the 3 wire Onan 3.6 ky gen remote switch (start, stop, com; start wire to COM, stop wire to CoM) the wiring to the relays would be different than that for the cerbo gx I understand from Victron that the CCGX relay only completes a circuit How would these factors change the wiring diagram I saw in the video?

Thanks Chris, Okay - Now I understand the relays - why there is 2.. Yep - there's a start/stop switch in the forward wardrobe - going to almost immediately above the Cerbo in basement. I move the switch position last year. It has a rocker start/stop and the run hours gauge. There's a brown (with jumper), red, blue, green to rocker, and a brown and orange to hour gauge. How would I determine the wires for the relay? Only way I could describe it as I can't send photos over youtube. Also did you connect the other ends from the relay into the Cerbo relay port - I assume so. The Cerbo came with all those plugs/attachments on the bottom - 5 in total. I see in your video you had them all installed. Is that necessary or just the ones that are in use - or is more the case of installing them so you don't lose them? Thanks for your help.

Hi Trying the same thing by connecting my Victron color control gx to my Onan 3.6 my gen via the rocker switch wires Assuming your switch is like mine one wire is common, one for start, and one for stop. When the start side of the switch is pressed it connects the start wire to common until the switch is released. The same occurs for the stop function.after removing the wires from the switch Using a multimeter you can determine which wire is common then connecting each wire to common will determine their function Btw, my panel also has a prime switch but the Onan manual states the propane gen does not require priming

Wow Chris. I watched this video you suggested, and I didn't know what the Cerbo GX could actually do. WOW!! Most enlightening. Much more than I expected. Firstly, the generator control panel in the video seemed fairly large. I'm not sure if it is the main AC control panel or a separate panel. I don't recall such a panel in my rig. I too have a Montana pre-prepped and with a factory installed Onan 5500LP factory generator but don't know where this panel is located. ?? How did you connect the outlet from the relay to the generator? Secondly, I know nothing about relays, but why 2 relays? Can't one switch on then off? Also, what are the required specs for such a relay? Lastly, the wire you used. I can see it is a 4 core wire L1/L2/N/G (not sure about gauge) but you were connecting a 30A inverter using only 3 wires - you didn't use the red wire. For my 50A Victron pass thru MultiPlus-II 2 *120V, I require the same type of cable but I have to use all 4 wires. Could you please tell me what cable you used (gauge/designation grade), and source (Home Depot?), etc. I also saw it was a solid core wire as opposed to a stranded wire - why? Chris - I live in Australia but I have a Montana 3130 in North America and have travelled there since 2018. These questions may seem mundane, but I trying to tackle/understand the US requirements over that of Australia. Thanks for all your assistance Great channel Regards

The “generator control panel” you’re referring to is for the iN·command system which is a screen in the Montana that controls pretty much everything. Including the capabilities of starting and stopping the generator so I used that spot to tap into the lines that run to the generator to start and stop it. Every RV will be different. Does yours have some form of generator start stop button and control panel inside your rig? Essentially those wires is what you will be needing to access. The relays connect to the wires that feed the generator control. You need 2 because to “start” the generator you need to apply power for a couple of seconds as if your pressing the start button on the generator. And a different relay to just send the stop signal for a second. Rewatch this video a few times you’ll see. The relays I used are very particular with links in the description of where to get them. You can’t have just a normal relay that’s NO NC type thing because you’d be “starting” the generator non stop even after it starts. The starter would just be running the whole time. Make sense? Again, check the description for the info on the relays. I used wire that I had available and could carry the load my generator puts out. For yours you’ll need different gauge wire. If your generator only has one leg of power, you can simply jump it into two legs of power. There’s videos on this type of thing. Let me know what else I can help with.

Hello, Do you use your lithium battery bank for your generator or do you use an aux battery for the generator? I'd like to use an AGM for my generator.

So I need to keep it charged and maintained. Thanks, Earl

Hello, thanks for your video. I live in Germany and here you can't get any information about connecting a Cerbo GX to a generator. So thanks again. I have two more questions. First of all, in your cable routing, it is difficult for me to see where the red, green, orange, yellow (black and red) cable leads. Do these wires end in relay input 18? Question two: With how many amperes do the 12 v run to the Cerbo GX. It would be great if you could help me with that. Greetings Ringo
@WhyNotRV
2 жыл бұрын
The yellow and red (on the front side of my incommand panel) I tapped into those with a red and black wire that lead to the relays. Those go into the number 18 input on the relays (one to each one). One is to start the genny and the other to stop it. The cerbo is just a switch. It has amaximum input of 24v and 1 amp. It just sends the signal to the relay that has the higher amp capacity to talk to the genny. I believe 16 amps. again, you are just sending a signal to the generator so the load is pretty minimal. It is just about sending the signal to tell it what to do. I hope this comment helps you and others reading. Thank you for watching and reaching out.
