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 😊

@@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 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)

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.

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
2 жыл бұрын
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 👍🏼😃

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

Just about to take the plunge on van electrics and Greg's video is by far the most useful on KZitem. Whenever I'm nervous about jumping in I watch this (for the umpteenth time!) and feel reassured. Top man! Not sure if you're still monitoring this Greg as you're currently on your Portuguese jaunt with Lou but I'm wondering whether to use common bus bars for the MPPT/Inverter/DC-DC etc units as Alex has done from Mispronounced Adventures or whether to run them directly as in your diagram.

Hi, great videos! You have helped me a lot during my van build. Could you kindly help me with a question… I’m connecting two solar panels to my solar controller tomorrow and I was wondering if I can just solder them instead of using mc4 connectors? I brought two mc4 branch connectors as four wires need to connect in two from the controller. The connection is just terrible and I was very tidy on crimping them. This connection is inside van so doesn’t need to be a water tight seal but I do need a strong connection! I pain on soldering two positives to the positive and two negatives to the negative. And make sure the put plenty to heat shrink so they do not connect in the wall space. Your thoughts on this would be very grateful Many thanks Justin

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?

Hi Greg, as always stunning video. I am going to wire my van soon and wondering when you are on electric hook-up in the campsite, does your 230V power supply goes directly to your 230V accessories, or do you still use the inverter. I'm thinking about so bypass of the inverter when on the hookup. Is that necessary? Or am I just overthinking? It will be mainly for the fridge, my son's PlayStation, and the microwave. Thank you

You can put an ATS on the 230volt side between the hook up supply and inverter supply. So if it detects a main hook up it will automatically switch over to mains and drop out the inverter supply. Then off the switch you only need one set of wires and sockets in the van 🚐

Hi Greg, I've watched this video "how-to" already in 2019 when it came out (and most of your other van building videos). Very entertaining and informative, and it's also awesome you're still available for questions on this "old" topic/video. As for new insights, would you need to upgrade your schematics for any USB 3.2 charging ports to use slightly thicker cables, because those have specifications up to 100 Watts for charging power hungry laptops and tablets. Or is the 1.5mm cable still okay for that?
@GregVirgoe
2 жыл бұрын
That’s a great comment and you are right to mention the upgrade in cable sizes for some sockets. 2.5mm cable would be needed up to 3m long run anything longer may need to go up to 4mm. That also goes for cigarette sockets as they can use up to 15amps. Check cable sizes using the handy free calculator on this page www.12voltplanet.co.uk/cable-sizing-selection.html

The electrics worried me but studying your vids and work has given me confidence and this layout will almost certainly be my layout, just a quick question a chap called Calvin podina has commented on this and says an alternator charging option is missing . Is this an essential item or not needed with this layout , if so when would one use one .

You can add a DC to DC charger to this layout quite easily. That would allow you to charge the leisure batteries while driving.

Hi Emma, I’m glad you found my channel. I’m sure it will help you. If all you are using is the laptop go with a smaller inverter. It will have smaller loses and need smaller fuses and cable sizes.

Greg thank you so much for your video, they really are the only things I've found that make sense to me. I have got my solar kit and am trying to work out how to rig it up without disaster. The inclusion of the DP Isolator between the panels and the charge controller makes sense to me. I watched one video where someone insisted on the need to unwire the PV wires from the charge controller before adjusting batteries ect, but then he went on to touch the bare ends of these wires - its all baffling to me. I looked up the isolator in your kit list, 32A on ebay, but says its rated for PV string volatage of 300-1000V. I'm not sure how to calculate the string voltage of my panels, I have two which have 41V written on the back of them, they will be wired in series, so if I add that together I get something like 80V - could this be right? Can I use this isolator? I do I need something rated smaller? Thank you so much for any help, I know there is really no obligation for you to help some random asking you a question, but the company I bought the kit from seem to find my questions tiresome. eeks.
