Main takeaways are at 16:33 - Use appropriately thick cable - Use MPPT controller if you have a large solar panel bank (otherwise PWM controller fine for smaller panels) and keep controller as close to battery as possible - Keep your solar panels clean

and just like that ! my solar charge is back to normal. i seriously dont know what i'd do without your helpful 12v episodes .

I'm up on most things electrical, and as a 4WD and Van owner I commend you on your video explaining this to people who don't understand. I have seen some shocking installations over the years and what is surprising is that a lot of Caravan manufacturers are using the wrong size cable. Remember most Caravan manufacturers are like used car salesmen and will cut every corner they can. They don't even balance the wheels on your van from new.

One thing a lot of people don’t realise regarding the length of the cable is that with DC the run is both ways, so this has to be allowed for in your calculation regarding cable size

@@donherley1811 correct, which in short runs of 1 or 2 meters is no big deal, but if you have the appliance 5 meters away it is a run length of 10 meters which In most cases will require going up a wire size to prevent voltage drop.

What amazing people you two are, a genuine credit to the 4wdrive public, and your episodes are amazing.

I really appreciate these videos where you try to simplify electrical systems for those of us who know absolutely nothing about electricity. I’m so confused, but your videos help! Voltage, watts, current, amps, DC, Inverters, regulators, resistance, 12 volt… does my head in lol 🤦🏻‍♀️😂

That was amazing, showing the difference in amps received, just from changing cable thickness. Thanks for making the video 👍

Thanks Keelan I'm 65 female and just starting out on the road. Your knowledge is easy to digest. Learn something everyday. Safe, travels to you and your family.

The easiest way to explain the difference between a PWM and an MPPT controller is that the PWM controller is pretty much limited to the voltage it sees from the panel, if the panel is proving a high voltage this type of regulator will simply clip it, the battery will charge but not as efficiently. These can work well in sunny conditions, in shady conditions these can limit charge to a point that they are pretty much ineffective. A MPPT charger on the other hand ( think ohms law ) can convert the higher input voltages from the solar panel, to the 14.4v / 13.8v ( charge profile specific ) and increase the amps, rather than just clipping it. It provides a better charge cause it makes use of excess voltage by converting into amps. This is why an MPPT charge controller will provide better performance in shady conditions. Especially when mated to a higher voltage panel. Keep up the good work! Keep living the dream!

@@SarahandKeelanTravels that's one wire of a 2-wire system - you don't mention earth returns at all & they corrode though usually slowly enough you don't notice till a big fault develops. Earth returns require an absolute minimum of the same thickness cable & they need to be dismantled & cleaned up regularly. Earths are frequently overlooked.

There are squillions of off grid videos, but this one is, in my view, one of the best I have seen. Explaining 12V systems is a blind spot in the other videos. Well done.👍

I have been a sparky sinse the late 70s. This is the best informative clip for the average person I have seen. Well done.

Great vid. Likely the best I’ve seen showing the real world examples hopefully will really drive home the importance of using the right size cable

Great video Keelan! I'd add that most wire manufacturers specify Ohms/foot. From that you can calculate total resistance for a run of cable and if you know source voltage and load resistance, you can calculate total current draw and voltage drop to the load.

I use a DC amp clamp and a thermal image camera for my installation. I use a DC-DC converter to charge and compensate for voltage drop, you need to current limit the charge. Using a 62V solar panel setup (560watt) with a MPPT, works great! Hello from the States!

Thank you for explaining it in easy to understand terms. Very helpfull.

I can Susan! your awesome thats why! back yourself! thanks for watching!

Nicely done. Good demo to show the effect of wire resistance on voltage drop. For the math, I just did a little calculation for 50 Amps across 20 meters of copper wire. For 6mm diameter wire, voltage drop is 3.3V, power loss is 165W. For 16mm wire, voltage drop (V = IR) is 1.21V, power loss (I^2R) is 60W. So, if you're running high current on a long wire run, and you want it to be efficient, fat is where it's at. Fat wire, that is.

Gday Sarah and Keegan. That I think is the best explanation of how to get the most out of a 12 volt system that I’ve heard. I’d never heard or considered the voltage drop from the regulator on solar panels. Thanks for the tips 👍🏻

Lots of great info about wires and DC charging. As an electrician in the US I try and explain wire size like a garden hose. Larger diameter hose will carry more water. A thinner hose must have higher pressure to try and flow the same ammount of water. Of course even higher pressure can only do so much (resistance) will still not allow as much flow. I love the term "Sparky" I try my best not to spark myself when working...
