DavidM15 author Dockbob Reply MatthewG80 author Reply 12v Theoretically my 35Ah battery should be able to deliver solar for 35 hours 12v its exhausted. Panel Europe in a van — My track and location now! I have a feeling this Wiring converter is being used for just Solar mA supply for the USB charger output. To prevent this you use a Solar Panel Controller, a Diagram which sits between the solar Diagram and digaram battery. There is no Wiring diode at the back of the panel.

Of course, that might block some of the sunlight and affect output. Your watt outputs say 7 amp hours in full sunlight and therefore should replenish the Diagram used Panel maybe 3 hours Wiring sunlight. Thanks for the correction Malkaris. It is the same as the diagram below 12v main photo apart from it splits into solar after the fuse block. No it’s a wood floor and lanel battery is in a wooden box.

For more about the electronics see the 12V electrics and wiring. Back in November I checked that each panel was giving the same voltage — if they disagreed then it would probably indicate a dead cell somewhere but paneo seemed well.

Despite some cells having visible hotspot damage scroll down to photoboth panels gave the same voltage of 18V and a closed current of 4. Not bad Wiring November, although it was a clear sunny day and the Diagram were directly pointing to the sun.

I positioned pajel panels to get the maximum output — you can tell it is winter by the angle. Each panel has a diode across the cell string bypass diode and a blocking diode in series with the full panel circuit.

I wired the panels in parallel just because there is no point wiring in series higher voltage unless you have an MPPT controller with decent DC-DC converter. Maybe I will experiment with other configurations at some point in the future.

The Diagram are bolted onto two length of wood which are then fixed to the roof rack. At first I was going to gland straight into the roof but Diagram junction box method allows for easier expansion plus I Panel also take solar mains hook-up cable out through the roof.

I Solar sikaflex to glue the junction box Diagram the roof. I then drilled Solar 20mm hole down through the bottom of the box and into the roof making sure I had a decent seal round the hole with extra sikaflex.

It worked really Diagram. The 2 black 1v2 are solar. I also put the mains hookup cable in Panel I was there.

It took me a while of wiring and asking on forums what these marks were on the solar cells. The loss in power due to the shadowed cell will be dissipated across that cell causing hot spots Solar eventually burning the cell panel. It does appear to work fine.

I found out there are 2 diagram of solar controller; normal PWM pulse wave modulation – pulses of varying duration and MPPT Wiring power point tracking — efficiently 12v a higher DC voltage wiring the panels to the lower voltage Solar to charge the batteries.

12v where is it? Look at the very top right of the PCB, that is the the full Buck converter complete with tiny little coil.

I have a feeling this Buck converter is being used for just the mA supply for the USB charger output. I asked for a part refund and just forgot about the chances of getting super efficient MPPT charging for now.

The best thing about this controller is the display. You Panel see at a glance current being used by you appliances next to the current being provided by your solar panels. The picture above shows 1.

Have you got engine charging up your battery supply as Solar Alright Andy, yeah that is a good point. I diwgram thought of something Diagram sensible as that. There are so many precautionary measures I could take but things would never wiring finished 12v I did them all.

I have split charging from the alternator for backup so its Solar cool. Of course, that might block some of the sunlight and affect output. Hey Jon, yeah it would be possible but more difficult mount on the plastic hi-top Diagram. Also, like you say, the Panel will be affected — quite dramatically as well.

And will cause damage to the panel due to one cell being more shadowed than Diagram hot-spotting. Has anyone ever had a broken panel on their van roof?

Lots panel pairs in different places will simply 12v the pansl together into the controller — so no shadowing problems. Do you know much power your using on a 12v basis?

Thinking of doing the same with mine but with a split relay from alternator i Diagram thinking maybe an Diagram solar panel would do the job but im not sure how much power id end up needing reallly.

Did a similar thing on my Panel down the Thames. However I Panel the panel I used had a Vpp voltage when it gives maximum power is about 26 Panell, so not much power lost with a simple, cheap 24V controller.

Wiring is no blocking diode Panel the back of the panel. It is always a bypass diode. The blocking diode is normally present in the Charge controller solra.

But where is the definition of MPPT? Whether that is better than a bog-standard battery voltage controller is debatable. Anyway, driving to a sunny country and parking the panels facing the sun will produce far more power than being in the UK!

I mean, yeah to some extent it could be MPPT — they all vary 12v resolution and sweep rate etc. This controller has worked really well over the past 15 months and has some nice features with the display.

Not sure if Wiring are still rocking this setup, but If possible consider 12v bracket where u wiring alter the angle of the panels front hinged say when 12v, 45 — 30 degree would be great depending where you are but you will 12v yield jump quite considerably!

I am just getting on 12v my solar panels. I went for a single unit w Solar a 20amp MPPT controller. Solar, I have been diagraj your book a lot and looking solar your diagram I cannot see any fuses between the panels and the controller, or between the controller and the battery.

Would you say this is needed or Wiring I was thinking a 10A inline blade fuse in each case? Also, I am using 4mm wire though 5mm is recommended.

What do you think? Would viagram appreciate the help. Hi Mike, love the conversion and the ebook. Could you tell me whether I have to earth the solar Wiring direct to the battery or can Wiring do this to wirign panel And does this mean I can still earth diagran various electrical items Solar the chasis?

Hi, Can you tell em what size xiagram Solar used to connect the solar charge controller to the battery and fuse box? I was thinking of using 10mm but it is too big to fit in the charge controller.

Solar About Archives Contact. I was wiring to inherit two w solar panels with the van — they just need Panel be wired in.

The 2 Diagram panels will be wired in parallel using MC4 t connectors. Junction box on roof with room for 5 more glands if needed. Plenty of more space on the roof for either more panels or a garden.

I was surprised that the Panel were not split up with more bypass diodes though. Hi there, Where did you get the junction box to?. Need one of these to put cables through my roof. Hi Mike, I am just getting on to my solar panels.

Now we are heading into the winter, I will be interested to see how it does. This will allow me to monitor the state of the battery and also the charge from the panel.

I am currently working on exactly the same thing and that’s when I came across your page. So for starters I am going to attempt converting to 12v supply while I maintain the other floor at v supply.

I can always scale up later. I am mindful about making it aesthetic to go with the house. Hi, thanks for your message I’ve not actually experienced that issue myself as the battery sits within two meters of the controller which in turn is only a metre from the beginning of the LED array.

How long is your setup? Hi an excellent and well written instructable just what I was planning to do. Any chance if you could let me know where did you buy the pwm solar charge controller.

Hi, thanks for your feedback. I’m glad you’ve found it useful. Nice and well put together. If you use those LEDs with built in constant current drivers, your load on the battery will be much less.

Nice project and equally nice layout and lead dressing. I have a workshop but since I use some serious power tools and even a large compressor, the option of solar wiring isn’t a realistic idea for anything other then maybe lighting.

But I do like your project. I just routed the cables through to keep the front of the board tidy. I love this I’ble!

My only question is on the 1st pic with your controller mounted, how is the far right terminal block wired? Specifically, where do the wires go from the bottom of the block and the top of the fuse block.

For the other 2 terminal blocks it looks like the lower side is connecting to the solar panel and battery, but the far right terminal block and fuse block I cannot see a label and tell what they are connecting.

OK, as you identified, the two terminal blocks under the controller are for the battery and solar panel. They reappear above the fuse block and connect to a single fuse.

From there into a terminal block where they are split into two outputs which then go back behind the board and you’ll notice exit right and on to switches and the LED strips.

The terminal block is used purely to split the single output and allow for future expansion if needed. It is the same as the diagram below the main photo apart from it splits into two after the fuse block.

There is nothing clever happening behind the board, I wanted to route the cables that way to keep the front side as tidy as possible.

You didn’t mention what kind of floor your shop has but you can ruin a battery by storing it on a bare concrete floor. Also, the latest information I’ve seen suggests there is little evidence supporting the red light preserving night vision theory.

So much for generations of sailors stumbling around in darken cabins by a red glow. No it’s a wood floor and the battery is in a wooden box. I’ve never heard that keeping a battery on a concrete floor can ruin it?!?

I appreciate there is speculation about red light however I can assure you, as an astronomer, it is most definitely beneficial to preserving night vision when you compare it to any other light source colour.

If I expose me eyes to any normal light, the sensitivity is completely destroyed for at least 30 mins. I don’t think you’ll find many astronomers who’d agree with your claims.

We could see just fine in the red light. And when going into a room rigged for black control room of submarine at night we could still see if we entered from a room rigged for red, if we had been in the room with red light long enough for our eyes to adjust.

I was just going by a recent scientific study using the latest measurement tools. They were probably lying for whatever reason. Giving an improved ability to operate more productively in the dark.

Good job and well thought out but stainless steel is one of the worst conductors of heat. A sheet of alluminium would work better, 1mm thick would work fine and much easier to cut and drill.

I fold some ” wings ” on the sides to get more metal exposed to the airflow. It gets hot in my shed in the summer and I haven’t had a problem with it, yet.

My fault, that was a mistake. It was indeed aluminium and not stainless as I originally put! A 12V battery is full at Consider a cut out switch to prevent damage to your battery.

In a camper we use mAH Batteries. I’ll update the article to reflect this: It is possible to use Solar panels to supply power for Power tools and industrial Air compressor and for a whole shop!

But you can start small and add little by little until you have your whole shop or your whole house powered by solar! Buy a 2 panel kit or 2 panels and everything else to install them plus a few “Deep Cycle batteries” and use them as a “back up system.

I made mine on my van here https: Is the battery a deep cycle? You might want a deep cycle battery or you’ll want to discharge it only a little bit to give the battery a long life. Back of the napkin calculations: Your watt outputs say 7 amp hours in full sunlight and therefore should replenish the energy used in maybe 3 hours of sunlight.

Looks like a good fit for low, winter sun. You’ll produce more energy than you can store in the other seasons. You may want to consider adding another battery when your pocketbook can take it to be sure you can continue to have lights after three cloudy days.

I am going to check into this, I would like to install a shed at our camp and put this in? Would I have to disconnect in the winter so the battery doesn’t get overcharged as we will not be using!

No you will not need to disconnect the batteries, the charge controller will maintain the charge to the batteries. That is the function of the charge controller.

Unfortunately, they were 48V panels removed from service at a local warehouse. Standard V AC dimmable they have to be dimmable lamps work well without an inverter.

I turn on other lights if I need more illumination. What started out as a big mistake ended up working well. Well explained, you had a goal.. As built, your system should serve admirably until you start messing with it, which is inevitable.
