How to Wire your Camper Van to be Off-Grid

[@GregVirgoe]

YOUR QUESTIONS ANSWERED HERE - Please read this first. This video is always going to bring up a lot of questions so to avoid having to answer the same question lots of times I’ll post the most common answers here for you. 1. Why have you not got a split charge relay? A. AGM batteries do not like the voltages given out by your alternator and if you want to charge the leisure battery while driving you really need to fit a battery to battery charger. 2. Why have you connect the red and black cable on your solar panels. A. These are wired in series so it is correct to have them connected this way. Please watch my solar panel installation video for more detailed information. 3. You have not connected a load to your MPPT charge controller. A. This connection is for small load use only say just to power some lights. You could not connect 50A of appliances to these terminals. 4. You have not connect this system to your van body. A. The van body is not an earth it is used by your auto electrics as a neutral. I personally do not advise using the van body as a neutral for your leisure system. My mains earth is connected back to my hook up socket and I always check with a plug tester when connecting to shore power. 5. How can I size my cable and fuses. A. To work out the amps required use this calculation Watts / Volts = Amps. For fuses take your max amps figure and add 25% for safety. That is your fuse size. Then add at least another 25% and choose a cable bigger than that rating. 6. The interconnecting cables between batteries need to be rated for the sum of all your connected loads assuming that there may be running all at the same time. I will update this pinned comment if I get lots of other questions if you can find your answers below please do leave me a message. I do love reading all your comments whatever they may be. Thank you 😊

I live in NYC...can i connect a 12v heater for winter time in this installation or is it better to buy one of propane? Also 12v sistem for hot water in the shower?

[@RiazRJ]

Superb video as always 👍🏼 Question, having used your van a fair amount would you say you’ve got a big enough battery store?

[@richardd8352]

@@JuanMartinez-pw4xi I would avoid any 12v heating source for winter off grid camping. If you are hooked up to mains the its ok. But heating elements will put unnecessary stain on your system. The best off grid setup would be a static fitted gas fire, with independent added blowers for heat circulation. Blown propane heaters are not ideal as the system requires continual 12v during use for fans. I run a diesel fired eberspatcher but the 12v consumption is very high. Remember no matter how many batteries or solar panels you must get a good balance for winter off grid surviving. Also absolutely no 12v fridge, just go propane. Fridge elements are high draw items. Maybe restrict 12v operation of fridge to high harvesting days for solar, but again during winter the effectiveness of solar even on sunny days drops dramatically. You can somewhat negate winter sun by angling your panel on an adjustable bracket depending on where you are in the hemisphere. Flat panels can lose up to 50 % efficiency compared to a correctly angled one.

[@GregVirgoe]

Juan Martinez simple answer would be to avoid electric heating of any kind from batteries. It will use so much energy really fast.

[@davidfrowde338]

Could I ask if you have a reason for not connecting to the van body, every other video I have seen shows this and whilst I thought your video was excellent it has left me unsure what to do now? I am using the Sargent EC155 as my main electrical control with additional 12v fuse board, although I now wish I had done it myself from scratch.

Dear Greg, you are a born teacher! I've looked at a lot of van conversion videos and what has put me off has been the electrics. Even if I got someone else to fit the electrics, I still need to understand it in case something goes wrong. Your slow and calm explanation combined with that very clear diagram is awesome. As I said, you are a born teacher. Thank you.....electrics now demystified! I'll be binge watching your other videos and I might just (finally) take to the road off grid.

[@mobaumeister2732]

Great explanation, clear and concise, no fluff. However, how are you wiring to your 230V plugs from the inverter, re you simply using extension cables that plug into the inverter?

[@GregVirgoe]

You can use 2.5mm three core cable plug into the inverter then wire into the back of 3pin sockets. To keep it simple you could use an extension lead with multiple outlets just be aware that the plug fuse will be max of 13amp or do not use more than the watts rating of the inverter. 😃👍🏼

[@2secondchance2]

BrilliNt video. The one thing I am worried about when looking at a van conversion was the wiring. This video spells it out plain and simple. Brilliant!

[@fireblade1007]

Great video Greg did you wire your van in a way that you can also charge your batteries off the alternator?

[@GregVirgoe]

Fireblade 100 no because a simple split charger is not compatible with AGM batteries because the charge profiles are very different. I could do it with a battery to battery charger but they are bit more expensive. Great question thanks for watching.

[@vangeezerexperience]

@@GregVirgoe Yes, that's what I had to do. I bought a CTEK D250 charger. Absolutely fabulous product (no, no affiliation :) ) and well worth the money (appr. £ 170) if one travels in places with less sunshine and/or off grid (Scandinavian wilderness).

[@mrxracing9193]

if so what size cable?

[@djsmiley01]

@@GregVirgoe You might look at the Renogy DC charger. I've just bought one. They are pretty cheap (110 eur for 20A and 140 eur for the 40A version). I found them on the French website, and contacted their German office since it was in stock, and they were able to ship abroad (the Netherlands in my case). I also wanted one, because of the charging differences between AGM and a regular lead-acid I needed one. As for the cabling: In the end you're mentioning having the same cable size as the biggest consumer to wire the batteries in parallel. I think it should be even bigger, since you can (theoreticly) use both the inverter AND the other devices at the same time, so in your case with a 200 and 50A breakers for those parts, there *could* flow 250A in total (Altough this is highly unlikely). Good to mention the use of stranded cabling and not solid. But also, especially in the higher current circuits, proper crimping is just as important. (And don't solder, since that is also not recommended in a moving vehicle). Finally, for the campsite hookup: Just beside a breaker, I highly recommend installing a RCD. (I personally am installing an surge protector as well... I've seen some crappy campsite installs...). And if you don't like the big CEE campsite connector (just like me) you can install a DEFA socket (which is much smaller, and can be fitted in the front gril or somewhere else). I'll just carry an conversion cable with me. DEFA is pretty known, especially in Scandinavia for heating purposes, but it can handle up to 16A. Here in NL its not much used besides construction vans, but I still like its small size (I can fit mine behind the fuel cover on my Ducato)

[@GregVirgoe]

Paul Carter what I did to start with was to list all the things in my van that would need power. Decide what item I was going to buy then find out what each of their power requirements were in terms of 12v / 230v and the amps so I knew what cable to run. Lastly did a simple pencil sketch of where each item was in the van so I knew where to pull my cables to. Hope that helps 😀

[@MrPc924]

Greg Virgoe what goes after the inverter? How would you connect all the 240 plug sockets to it, say if I had 3 plug sockets for instance?

[@GregVirgoe]

Paul Carter most inverters have a three pin socket so you wire a 2.5mm 3core cable to a 3pin plug. Plug that into the inverter then wire the other end to your sockets. You can only plug in devices rated below that of your inverter 👍🏼😊

[@mannys4036]

This was the best and most clearly spoken explaination regarding the installation of a 12 volt system ever. I live in US so there is a slight difference, but the mechanics are the same. I have sought out and watched many KZbin videos but yours is by far the best. You speak so clearly and at just the right pace explaining in a very simple clear cut manner.

Adam Vincent-Garland best way of doing that is with a battery to battery charger. That way you can set the correct charging profile for your leisure batteries. A hook up lead with sockets on the end is a cheap emergency back up nice to carry if needed

[@Vandemonium]

Forgive me being so impertinent as to make a suggestion but at the end you said the battery interconnects should be sized to the draw of the highest power appliance. I would suggest they should be sized larger, to the sum of the highest power appliance plus any others that might be running at the same time, since the total draw from the batteries will be the total drawn by whichever appliances you’re using simultaneously. Eg if 2kW inverter is running full tilt and your fridge is on at the same time, you’re drawing the sum of both those draws.

[@GregVirgoe]

Vandemonium you are absolutely correct David and well spotted. My explanation was not technically correct in that instance. The 35mm cable is good for 240Amps so that will easily cope with everything in this diagram. The interconnect first need to be sized for maximum simultaneous demand on all systems.

[@tradedemo8500]

Thanks for the video and also for the step-by-step presentation. I have looked at some of your other videos, e.g. battery and solar panel sizing, as well as the choice of cables and fuses for the loads. I have made a couple of observations that I need help with. * You have used 3 x 160W solar panels wired in series, which will increment the voltage. What is the cumulative voltage in this case, and also what is the maximum voltage that the MPPT controller can support? * You have also used a DP switch between the solar panels and charge controller, but it is not clear the size of this switch and what device is being protected, considering the fact that the solar panel amperage remain static. Would you suggest an in-line fuse close to the solar panel in addition to the breaker? * Finally, it seems like you have a 50Amp circuit breaker between the charge controller and the battery and the same between the battery and DC fuse box, but I think the battery amperage is 110Amp. So if I am right, what is the circuit breaker capacity lower than the battery amperage? Also, I am not sure but when the batteries are configured in parallel, does the amperage add up and if so, what should be the appropriate breaker capacity to protect the battery pack? Thanks in advance.

[@GregVirgoe]

The combined voltage is around 60-70volts and is within the 100v limit but check as other controllers do differ in spec. The DP switch is just for manual isolation if I want to turn of the solar panels. An in-line fuse of 15Amp would be suitable for this setup near the panels. The circuit breakers are sized based on the connected load downstream of the breaker and no relation to the size of the battery bank as it’s relative to what is being used. Check out my cable sizing and fuse sizing video 👍🏼😃

[@MrBezulbub]

Spot on Greg, your whole series is amazing and such a positive thing to do for others. I have one question on solar panels. Are there any pros and cons between installing multiple lower wattage solar panels compared to a single larger wattage panel?

[@GregVirgoe]

I can think of a couple of advantages. Space saving and location layout. Biggest pro is the redundancy should one fail you can easily rewire it out of the system

Hi Greg, firstly I want to thank you for your videos not just on electrics but all your videos are amazing! Greg I have a question!🙈, actually I have several🤣 but I'll be more than happy if your able to answer this. I have to 2 x Renogy lithium 50Ah(100ah total) battery's and 2 x lead acid 105ah(210ah total) battery's. The lead acid are backup power... is it feasible to have a wiring system that would allow me to switch over from one power source to the other as and when I needed it? If so can a novice like myself(I wish!😆) do this kind of setup? None of my electrical system is installed yet.....thanks in advance.

[@GregVirgoe]

Hello Phillip, thanks for getting in touch. The biggest issue I see is these different battery types will have different charging and discharging rates/profiles Battery chargers need to be programmed differently for each battery type. These should not be connected together. You could install two stand alone systems and say use the lithiums for big loads like cooking etc. use the lead based batteries for small loads like lighting or usb sockets. You could use a changeover switch to divert your solar power from one charger to another on the input side of the MPPTs

[@philwilliams23]

@@GregVirgoe Greg your a star...I did wonder whether 2 stand alone systems would be better. Yes, I had wondered about some kind of change over switch for the solar. I guess I'll have to toggle the mppt parameter settings from lithium to lead acid when I use the switch too? Would a change over switch also be feasible on the dc-dc charger? (switching over between my lithium's and my lead acids). Wow, super thankyou for your prompt reply! If you want to film me (with your technical expertise assistance of course 😉😉😉) and make some video's for your channel could that work???😲😲😲🤣🤣🤣 cheeky I know....! You don't ask... you don't get!!😳🙄🤣

[@user-dr1fe8ke7d]

Wow, this was everything I needed right now, thanks so much for generously posting this fool-proof guide. There are loads of confusing (and differing) explanations, but now I feel ready to crack on! I used a video or two of yours in the early stages of my van conversion, and then forgot about your channel...really glad it popped up again at the perfect time...subbing immediately... My stealth camper is about to become a lot more civilised!

Hi Greg , hope your well . To run a kettle / TV off grid ,where would this fit into the diagram please ? Many thanks.

[@nickjeffery1259]

It's ok Greg , watched your other video on TV installation. Thank you

[@GregVirgoe]

I would recommend getting a small travel kettle no more than 2x cups and 800w then you can run it off an inverter. A domestic kettle would use too much power. 👍🏼

Just bumped into this while surfing up stuff for my own project. I've got a 13plate Crafter I intend converting to a w/e camper, not full liveaboard. I've made a start with the floor, windows, roof vent and bed in. My next thing will be electric for lights, power, inverter and fridge. So to find a well made, easy to follow, breakdown vid of how too has been an absolute diamond in the rough. Thank you for making this and your other vids.You have helped my understanding of how to tame the 'angry pixies'.

[@nspinheiro.]

I am just starting to plan my Van and the eletricity is what troubles me the most. Its not possible to use the car alternador to also charge the bateries while driving or/and have eletricity when there is not enough sun? If the alternator charges the car battery makes sense that we can take advantage of it. Also, instead of a connector to connect to an homr plug, why not a plug equal to the eletric cars and plug it on a service station for example?

[@GregVirgoe]

It’s best to use a battery to battery charger also known as a DC to DC charger to charge using your van engine. A good model would be Victron Orion 30A. Always good to have hook up for camp site charging. Running the engine when stationary is not the best solution. 👍🏼😃

[@nspinheiro.]

@@GregVirgoe well not the best but if, at limit, is the only available, i rather have that than nothing. I am planning not being much on campsites.

[@GregVirgoe]

@@nspinheiro. you still get electric hook up on free sites across Europe and I’d hate to be parked next to someone running their engine to charge a laptop 😉

when you say 16mm cable, or 10mm cable, do you mean 10mm2? what are gauge are you reffering to? im getting so confused by the cable sizes! AWG, mm2, and then the nominal size. please could you help me?

This chart will give you the conversion encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcT2bfpHvjpnquN3FmnLZhZO8gOGuPugWnWWtQ&usqp=CAU

[@Fromatic]

@@GregVirgoe That was a useful question and a useful answer link, I was watching thinking "a 35mm (diameter) cable is enormous, how are you routing and attaching ends to that", but from that chart I see you were more likely talking about mm2 cross section which now sounds more reasonable

[@BarryDean007]

Why would the fridge wire change from 4mm to 6mm makes no sense, same fridge doing same thing nothing has changed

[@GregVirgoe]

The larger cable is to reduce the voltage drop. Most fridges need a big cable see your fridge manual.

I work with a.c. and cable sizes and protection are chosen by coordination. The demand of the appliance (Amps) must be less than or equal to the protection rating (breaker or fuse Amp rating) which must be less than or equal to the current carrying capacity of the cable. This is a great video, btw, and taught me loads about the setup in campers and caravans. Am hoping to buy a cheap van and convert it. Don’t hold your breath! 😂
