I cant remember if you mentioned the cable size from battery to lynx but If you run 70mm2 cable from your lynx to your inverter do you also need to run 70mm2 from the battery to the lynx?
I ran 70mm2 from the battery isolator to lynx, the smart shunt to lynx and then lynx to multiplus. We also used it for the chassis earths from the lynx and multiplus. 👍
Great video. I’m looking at 3000W inverter for induction hob and the company I’m going with recommend a 24v system but not sure. Did you consider a 24v system at all?
What are the benefits of 24v? No not really we trusted in the system designer to meet our power requirements but yes we to are running a induction hob.
@@abucklifethey said with a 3000W inverter, 24v will save more money because the wires will be smaller than 12v. That’s it really I think, still undecided though.
@@jackbebb566 They are correct however there are some considerations. Power=Voltage*Current thus if you up the voltage you decrease the current for the same power proportionally. This is why many DC coupled renewable systems in houses use 48V. The reason they have said 24V is probably because the choices are 12V, 24V or 48V and above 40V the potential is high enough to give humans a shock. Copper wires are heavy and expensive so 24V seems ideal, BUT a vast number of van/motohome/marine systems run off 12V and this may matter to you. For example if you have a 24V system, now you need to purchase a additional DC-DC to step down the voltage from 24V to 12V for all your 12V consumer devices (e.g. lights, aux sockets, pumps, fridge, chargers). The issue is that the DCDC will have an efficiency and power limit thus it may just be too much hassle for the benefits. The benefits are that your high amp loads now have smaller currents so items like the battery and inverter wiring are smaller gauge. In theory its safer to in terms of fire risk. Hope that helps.
Just had a quick look and if youre using 24V you probably need something like a Victron 24/12-30 (360 W). If you add up all your 12V loads, youll need 1 to N devices to step down the voltage. And remember these older Orions are only 88% efficiency which is bad for a modern buck dcdc converters. Must be betters ones out there?....
Thanks pal. I think your about right but that’s a ginny question as she speced the system. I’m just the fool that had to install it. 😅 what you have to think with a big electrical system is you have no need for a gas system as we are fully electric. That makes the pill a little easier to swallow.
Great vid Matt (& Jinny) Did you get the wiring guide you were both using for the Victron components from the supplier as it looks a valuable thing to have? Also who was the supplier please and did they create the kit for you tailered to your needs? Thanks! :)
Nice videos! Would it not have made more sense to have the batteries at the bottom? Having so many cables running around the batteries seems a bit strange?
Use a vacuüm cleaner and a string to suck the wire trough the tube. Use a sandwichbag and the begin of the string for bigger tubes.... Use the string to pull the wire or cable
Absolutely nothing wrong with anything you've done but sizing down on a crimper suggests something is wrong. Either the die is wrong, the wire isn't the gauge it should be or/and the lugs are too thin. A friend was having issues and asked my advice, I took one look at the lugs and they were far too thin. Basically I would be careful sizing down.
Thanks rob. I read in a few reviews of the crimped you may have to size down and we did so I think just a cheap ish tool with a bad die for one size. Apart from that it was a good bit of kit.
@@abucklife Yeah, the blessing of affordable tools making things affordable but compromise in the quality. You got it done. What Ive seen happen is the die join extrudes lug to form a couple of sharp edges but I didnt see this in your video.
Very true. No I did check for this and we didn’t have any sharp points. A decent lug crimping tool is over £300 which for a one off job it’s not worth it.
@@abucklife The hex crimps are silly money, can be over £1k for all the dies. TE make a different style of crimp that I think is around £200 but I believe you can hire the real deal from some electrical suppliers. So for the viewers watching as they are about to embark, this could be a good option.
Looks very neat work, with great cable management. 👍
Thanks Steve. 🤜🤛 the hardest part of the build so far.

Ahhh I see. I can’t believe there is that much in it. Although the cable bill does add up.

Great vid. Are those batteries really 1300 quid each? Or did i google something different?

Thanks stu. Yer we used Chris at bspk solar who designed the system to our needs supplied the wiring plan and components. 👍
Hi, Have you got the link to the hydraulic crimpers? (The one in description is the same as the electrical crimping tool). Cheers
I will sort it now. No problem. 👍 thanks for letting me know.
I see you have air duct going up ???
Great video
Thanks. Yer it just goes over the garage to the diesel heater the other side of the garage.
Nice videos! Would it not have made more sense to have the batteries at the bottom? Having so many cables running around the batteries seems a bit strange?
Thanks krad. Yer it would but space is a premium and I have a bike rack going in. So I don’t have space to have them in front of the wheel arches.
@@abucklife Ah! I see that the bottom row is indented. Make sense!
👍 there is a lot to fit in 😅
The cable sizing for the inverter is too small. Victron state in their manual 2x50mm cables not 2x35mm. The guide you have is wrong please check.
Thanks for checking but it’s not. We have used 70mm2 cable for the inverter. Where have you got that from it literally says it in the video?
Read the Victron manual . It states 2x50mm for 0-5m runs. Not 2x35mm or 1x70mm.
70mm is suitable for their 2000va model.
Just trying to help.
Thanks I will double check it but I trust my system designer has speced it right. Appreciate the heads up. 👍

Use the string to pull the wire or cable
That is such a good idea 🔥🔥

Yer o think for most diy van builders or similar off grid situations you are only going to use it once maybe twice and it’s a great budget option.
