Please never sellout like other YouTubers... I have no intention on building an off grid system (i have an ongrid system) but i still watch you clips for the interesting, in depth, information. Thank you!

One reason people stick with 12v is walmart and auto parts stores don't sell 48v parts. And when you are on the road you need to fix it quickly

Will, don’t get stuck on the idea that everyone needs 120 power in an RV or mobile application, the main systems almost all require 12v even if they will run on 120v as well. Slides, furnace, lights, jacks, hot water heater…Here in the summer at 90-103 deg outside, we’re a 43ft rv running 3 rv ACs, no one is running full off grid in an RV, just too inefficient to do so at our temps and humidity levels. Now in the winter a simple 12v system 2-3 lithium batteries (no inverter) 2-3 100w panels and your good to go, paired with propane for heat. So 12v systems still have their place depending on what you need for power. So keep going with the great 12v battery tear downs and videos, the simple system guys like myself really appreciate it.

Will Prowse, youve probably never heard of Keysight Technologies, but here at HQ all the technicians swear by your videos. This means a lot coming from a building full of engineers. Please keep up the great uploads. You got me into solar last month and i just wanted to say you are making a difference on all levels!

I'd love to see a video regarding 48V automotive/RV systems covering everything from tip to tail including 48V alternators and 12V stepdown converters. We have a off-road overlanding camper we'd like to charge (the proper way) from the tow vehicle while traveling and from solar while camping.

Thank you Will! Two extra expenses that were not considered in this video while using 48v battery bank in an RV: 1. 48v-to-12v buck converter for all the 12v loads (fans, lights, fridge, pumps, furnace, etc.) 2. A booster for jump starting the engine battery when needed (I'm guessing most buck converters can't start an engine). ... These plus the 48v alternator I would think could match or exceed the expense of thicker cables for a 12V system, maybe I'm wrong. But I agree, the 48v systems seem better quality.

I went 12v as I have a 12v fridge, a 12v tv, all lights and fans in my van are 12v, a 12v radio. I do have 240v microwave but use it for very short time. An off grid home would be a no brainer for 48v though. Love your videos, keep them coming

I have been using Victron now for 5 years zero issues. All a 12v system. Totally off grid on my hunting cabin in Florida.

You talked for 1:30 griping about people not using 48v and still using 12v. My opinion is that there are multiple reasons: 1. In an emergency they can use their 12v inverter off their car which is 12v. 2. Most people are unaware of the benefits of 48v systems. 3. They already have multiple DIFFERENT 12v batteries and 12v panels.

I went with a middle ground 24v system 2 years ago in my van as I already had a 24v 2000w inverter, plus the iceco frig I bought can run off 24v. And it’s been working well…I have 2 Victron 75/15 solar charge controllers one for 600w roof panels and 350w ground panels, 16KW of lifepo4 prismatic cells and it’s all worked well.

Keep in mind that smaller and older sailboats have 12V systems. If i should go for a 24 or 48V system i need DC-DC converters down to 12 for my instruments and often VHF. And to replace, fridges, depthsounder, speed-sensor, wind-sensor, autopilot, MFDs, GPS, VHF, lights etc to something that handles a higher voltage brings with it ALOT of money (guessing somewhere around 10-15k USD). And allthou i can run it with a DC-DC converter i will loose quite alot energy to heat, with limited space for solar, i do not have energy to spare. And the inverter for a small sailboat does not hardly get used either, so the focus for us is more often than not on the 12V-system. :) Thanks for the content!

Ham Radio usually requires 12v in the field. Lots of use for a 12v system. You are correct that most of them are small systems.

I have only a small system: charging my phone and laptop. But it’s honest of you to give us the truth. Thank you for your work.

Good points! I live in a travel trailer with lots of 12VDC stuff, so I have a split system with both 12VDC and 48VDC. For me, I like the redundancy -- if one system fails, the other is ready to rock. Plus, maintaining 12VDC provides a battery for the emergency disconnect system on the trailer brakes.

COULD YOU PLEASE DO A VIDEO OF A 48V SYSTEM FROM A TO Z. I HAVE A 12V, BUT IF YOU TEACH US, WE CAN SWITCH.

I built a 12v mobile system because that’s what I understand, going with a 24 or 48 you need more components like a step down to 12v. Your book really didn’t go into that. Love what you do keep it up and maybe one day I’ll wrap my brain around the bigger systems.

Hi Will, I have an answer and a reason for using a 12 volt system. When I camp (like at Burning Man), I use a lot of 12 power. I have a CPAP, laptop computer, multiple 12 V LED light strings, a 50 watt VHF/UHF Amateur radio, a 12 V refrigerator, a 12 V USB bank for charging head lamps and bike lights. All of this stuff runs on 12 volts. Why would I convert to 120 VAC and then have to use multiple 120 volt A/C to 12 volt DC convertors? Now I completely agree that for stationary systems 48 volts is the answer, 48 volts is much more efficient and lower losses. But when most of your stuff is 12 volts it isn't efficient to convert up and then back down again. I do also have a 2,000 watt inverter for charging a couple of tool chargers that only work on 120 volt A/C. So I believe that this is a case, at least my case for building a 12 volt system.

Will, in Europe Victron is 40% less price than it was in november. With 900$ you get Multiplus II 5000VA.

Because you have sung the praises and given us direction on 12v systems for years. It’s not like many of us can up and buy new equipment because it’s “better”
