Wow this is so over my old little brain! My limit is wiring a plug and "V=IxR" from physic lessons haha Amazed how so much is needed to keep the camper fully charged and more importantly Safe! Looks so removed from a plain van yet I imagine still some ways to go. Hats off to you Lee👍😺
Fantastic video and a lot of information that i will be referring back to over the next couple of weeks while im doing the electrics on mine. Your set-up is very similar to what mine is. Is there anything that you would have done differently if you had a chance?
Really enjoyed the vid Lee, was really hoping it was something I could maybe follow and complete my own install in the future but I've got to admit I did find it getting away from me a little. Think i will need to get a little guidance from somebody like the company you recommend for the equipment on installation aswell, but really enjoyed the video...
Great vid mr Lee 👍. Just what i needed to watch. Just one question doesnt the multiplus 2 have the trickle charge for the starter hattery when it has charged the leisure battery off 240v hookup ?
Great video. Very helpful as I am starting my own system design. May I ask, what was your reason for using the separate vehicle battery charger rather than using the trickle charge from the MultiplusII? I was planning to use it, perhaps I am overlooking something.
To be honest at the time I didn’t know about the trickle charger on the multiplus. I most likely would have used it, I might still end up using it and using the space on the board for the other mppt I have for more solar.
Hi Spyder . Where did you get the black back board from mate. Also the manual states bare wire into the terminals using 25mm is doable. The victron multiplus 12/3000/120 does require 2 x 50mm doubled up or 95mm with a 400amp fuse . Thats in the manual .
Black board is ply covered with carbon wrap. 👍 To be honest I rarely read manuals. I wire things up to match how they will be used. The manual only states oversized cables to reduce ripple but my cable runs are very short and the inverter won’t ever be running at peak for long periods. I like to keep things a little throttled back. Manuals will always give the safest recommendations (for warranty purposes)
You can utilize a relay on the MultiPlus to control the DC-DC charger, configuring it to open whenever AC Out 2 is active. Keep in mind that the inverter is rated at 3000VA, which equates to approximately 2400W of continuous power, with a brief capacity for higher output during peak loads. Additionally, you'll require two 50mm² cables for the 12/3000 setup as per the manual, and it's important to note that a 300A fuse will likely blow under heavy inverter peak loads. A 400A fuse is required for this configuration as per the manual. I hope this clarifies things for you.
The dc-dc charger is controlled through the bms so it can stop charging if needed by the battery state. The wiring and fuses are suitably sized to how the multiplus will be used and set up.
@@SpyderLEE The 12/3000 has a 5500w peak, just over 400amps depending on the battery's voltage. The Victron cable size required is not usually for current capacity but ripple. You can measure ripple, if it's high, it will damage the inverter and age the battery. The Multiplus 2 12v already has a trickle charger built in for a vehicle battery. I don't think you understood how you can use the relay on the Multiplus 2 to control the DCDC charger at all so I will just leave it. You should check out the trickle charger built into the multi and you can do away with an additional AC charger. Hope that helps.
@@sparkletornado5890 the cable runs are about 300mm long I honestly doubt I would see ripple issues in that unless I was sat constantly in peak. I didn’t know about the trickle charge at the time of install. This will be getting changed later so I can use the space for the second mppt. Victron specific help/advice is always welcome as although I have installed a lot of these systems they were very different 20 years ago and do a lot more now.
@@SpyderLEE You could rermove the AC charger and use that space for another MPPT for ground mount panels incase you are parked in the shade or need extra charging. If ripple is too high you will get an alarm. Its not a big job to go from 50mm to 95mm cable if it is a problem. You will get a good idea how much you have by setting the charge current to max 120A and use a voltmeter in AC mode on the DC connection. They will alarm around 1.5 - 2v.
Hi Lee, you lost me about 2 minutes into that video. I'm looking to get a custom built camper in the near future and the electrical part scares me to death. I'm so impressed with your knowledge on how to wire everything safely so my question is " would you do a custom build for me or is this just something you prefer to do as a hobby"
Just found your video. Brilliant talk through of your system, look forward to the next one.
Thanks 😁. The next one will be out soon. Just got a couple of promised videos first
Awesome that you go so in-depth of the wiring and super interesting! 🙂
Glad you liked it!
Wow impressive. That’s all I can say
Cheers. It looks a lot but it is less complicated than it looks.

Amazing video. Helped me a lot
Great vid. Just what I needed. I am way behind you on my build but your vLogs are great and just the right amount of detail.
Awesome, thank you!
This video is a gem, thanks Lee!
Nice job. A real 'fing' of beauty! 😊
☺️

I wouldn’t have bought the 12v trickle charger as I didn’t need it. I will be changing it later.

Thanks and yeah get in touch with energy solutions they can advise ☺️

Yes, it’s something I’ve only recently found out about. I might change the wiring at some point.

Curious why you mix redarc and Victron
