This is why this guy makes the best vids: no crappy half hour intro, no extra BS, just facts, delivered logically.

I have gained so much knowledge listening to this expert. I consider myself capable but electricity has never been my experienced skill or trade. I have wired my own on-grid shop did a good job. But electricity has many different layers. And the Automotive/RV side of electricity is beyond my skill level. However I am a quick learner and Will Prowse has helped me gain enough knowledge to start making some decisions about my 40 ft 5th wheel; that I want a 100% offgrid/unplugged solar powered electricity system. And with this RV I am starting from scratch, as it has zero in the way of integration of the 120 vlt AC connected/plugged in - RV internal system, but the 12volt DC system is tiny, with the waterpump, refrigerator, water heater and exterior RV lights being the only draws. I have no way to charge my 2 house batteries other than doing it myself with my own battery charger outside. My roof is large enough that I feel I could design and have a solar system that will not leave me wanting for more power. I am a usual sun worshiper; in that I travel to mild weather, with lots of local Sunshine. So I will have the ability, I just now need more knowledge to move forward. Watching these videos surely does help me make better and wise decisions. This solar system that I want will be my home on wheels, I am fully intending to live full time in my RV.

Will prowss you are very well spoken, also very educational! Thanks!!
Continue with your tutorias

[outthere]

Well said! I liked the summation at the end. Really put this 12/24/48v story to bed for me. Thank you!

[Grahamrjohnson]

Will, the Enerdrive dc2dc+ has a maximum input voltage of 45v and 40 amps Using MPPT, and can drive a 12v system just fine. Its the best of both worlds, cheaper panels and still using a 12V system that can be charged by the alternator on your All the other DC to Dc chargers I have seen have an unrealistic maximum input voltage of around 25-28V...

[Sovereign_Citizen_LEO]

The last sentence (or 2nd to last) just clarified what I should do. Thanks :)

[Wawaspmoqa]

Thank you for the useful information, already going with 24v just waiting for it to arrive.
You covered more than I thought I wanted to know, all this is new to me and trying to learn as much as I can.
Thank you again 🐵👍

[MrEdmundoGC]

thank you my friend, this video gave me an idea, i will use 2 550w solar panels a 30 amps solar charge controller, a 24v bank battery system and to dc to dc downgrade to 12v and conect it to a 2, 000w inverter so in that way i can take advantage of the solar panels better to charge the battery system and power my inverter.

[perryspecht]

So well explained. Huge costs savings in charge controller and cables alone. This video convinced me to change my build from 12v to 24V. Panels on top total 1050W. I'm planning 6 x 100Ahr Battle born batteries. Problem - How would I determine what shore power battery charger to use in this case?

[gregorygagnon]

I built your hand truck special, to the t. Love it in my bus.

[smilingdog]

Would 24v be better in a small house? Fan, refrigerator and lights. Once in a while tv and washer

[ForgeAheadwithMike]

So I'm doing a camper conversion with an enclosed trailer with standard exterior 12V LED lights. Each single light has the negative/ground attached the the frame (it seems most trailers do this). I already have 24V batteries that I want to use as my main bank. I plan to power the 12V trailer lights from a 12V panel (after the 24/12 converter) from my main system. In other words, I'm not using the tiny 12V battery that came with the trailer. The big question is if I have a 24V Victron Multiplus II (2x120), will the ground wire from the Multiplus (connected to the metal frame) interfere with the 12V trailer lights already installed?

Oh, and I plan to add a 24V solar setup as well.

HI LOVE YOUR CHANNEL WHAT DO I DO IF I WANT TO CHARGE 96 VOLT FOR BOAT PROPULSION ELECTRIC MOTOR 8 X 12 VOLTS

[rxbudian]

do you think Diodes can help with preventing parallel batteries from feeding the other?

[FroztiProductions]

So I should make parallel packs then string them in series with a standalone bms?

Or run series packs with individual bms and string in parallel?

Hmmmm

[bahumtongmukhim]

If I have 150w solar panels 2pcs which one is best for connection 12v connection or 24v connection is best? Please tell ne Sir

[theobotha]

Hi Will, I have a 12v Powerjack 6000w LF 220v out inverter. Can this inverter be changed to a 24v. I would like to change to 24v if it is possible. Regards Theo

[larryjanson]

but how do you charge a 24 volt system from a 12 volt honda gen? as not every day one can charge up the batteries by using the sun.

[leblancexplores]

I’m going to ask a stupid question. I bought the 12V VariCore set of cells to build a 280ah battery, could I have bought two 140ah somehow and series connected them to make a 24V battery with the same ah rating and benefited from some of what this video mentions somehow? I honestly don’t even know where to start if so. My Wh requirements are something like the 3300Wh the 280ah @ 12V battery provided.
