We have a 12 vote system on our RV because we started in 2018. We bought your book and used it as a guideline for how to do our project. I imagine there are many people who followed your book and are stuck with a 12 volt system. Other than Battle Born and Lion there simply weren't any other good batteries in 2018 and Victron was the only inverter at the time that was highly recommended. My 10 year 100 amp Battle Borns (4)have a long way to go. However if I were building one today I think the forty eight volt would absolutely be the way to go. The tech and competition has changed a lot in the last 6 years. Thanks for your programs. I have been following you since 2017. Best out there.

Though it should be noted that the MPPT 100/30 only supports 12/24V. And even though this is a 12V system, there is no reason not to buy a Victron that can do 12/24/36/48V. That make upgrading later on cheaper. So I recommend the Victron SmartSolar 100/20 or the 150/35. The 100/20 is $85. It is a really good value, though at only 20A it is really designed more for 24V and 48V system. Still, for a starter 12V system a 100/20 supports 256W of solar (12.8V x 20A = 256W). And always make sure it is a "SmartSolar" (which has built-in bluetooth), and not the "BlueSolar" (no built-in bluetooth).

That's even more of an issue if you are taking your vehicle/camper outside of North America. It can be near impossible to find a quality 12v pure sine inverter or charger in Guatemala or Peru. Finding the same in 48v... possibly a marine dealer in a large city may have Victron, if you are lucky. Likely you would have ask a friend to courier a replacement 48v item from the US (Customs duties?), else wait a few weeks for shipping. Amazon is not everywhere. I like the idea of 48v systems for all the efficiency reasons Will mentioned, but your point about general availability will likely keep me at 12 volts, at least for my international travel vehicle.

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.

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!

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.

You don't want to hang the ham rig off the home battery anyway, it is usually too noisy electrically (EMF/EMI). So for that case, and also for marine radios (less power but super-critical in case of emergency), you use a 12V down-buffer battery that is charged from the home battery. It doesn't have to be a big battery, just big enough to handle the transmit load.

I can answer some of your 12v questions. I have a large motor yacht that runs on 12v. Changing all the 12v panels and fixtures would be very cost prohibitive. My option would be build a 48v system and step it down to 12v at the panel. Next, changing to a 48v alternator is really expensive. A 48v balmar can run over 3k. To put that in prospective, a renogy dc to dc is a couple hundred. And, its not just changing the alternator. Your engine ecu is probably 12v. Your starter is going to be 12v or 24v. Basically what i am say its not as easy to switch to 48v as you make it sound. If you are building a new system from scratch, go for it, 48v is a great way to go. If you already have a large 12v system on you boat or rv, its not that simple. I have been looking into a 48v system for my motoryacht. The best i have come up with is a step down converter in front of the 12v panels, and a second alternator in 48v to charge the house bank. That would leave the 12v alternator to charge the start banks of my marine diesels.

You hit the nail on the head here. Any decent 48v Alternator is $4,000 +/- installed. Will seems to obsess over the cable gauge - which may cost an extra couple hundred dollars, when he says nothing about the $4k + expense of just the 48v alternator - and all the other 48v to 12v stepping needed for standard equipment. Sorry Will, 48v for most mobile applications outside of high end motor yachts or rail - only buys you efficiency but at significantly more cost.

A booster for jump starting the engine battery when needed (I'm guessing most buck converters can't start an engine). ...

Hi.

For my medium sized systems I run 24v, which again offers some versatility in being able to swap or agment with different batteries in a pinch, and run lights and appliances directly off the batteries instead of having conversion losses.

Hi Will. I've been off grid at my ranch for 50 years. First had a car battery and a small used ex military small panel. Then went to real panels (ex PG&E) about 35 years ago. Then to store bought and L16's about 20 years ago, With Outback inverters. I have upgraded the system more and more, now it is a 24V system, with 4 outback inverters. I run my wood shop all on this. I've got about 6kw of panels, and will go up to 10KW in another year, but the problem is now is that the old inverters are all 24V and so hard to really get to use as much energy I can generate with panels. I wish I could go to 48 V, but the inverters can't handle that. I suppose I'll have to get new inverters, even though those old Outbacks are still good. I keep watching your stuff as I need to know what to go to next! You definitely know your stuff. I run 220 and 3 phase in my wood shop, up to 5 hp motors (on 3 phase, with a VFD) I hope to go to a non lead acid, (currently they are the fork lift type of battery). I'd like a 48V (or more?) system, with the newest batteries, inverters and all, without paying $20K. Because of the woodshop energy draw, (and longer periods of rain ) I'd love to have a system that stores something like 1000 AH minimum. And inverters to handle 14,000 watts or so? My system was ~$2400 each inverter, and batteries was another $5K for the two, so it cost about $14K 20 years ago. Served well, but seems like I can get something better now for about the same amount of money. Those old Lead acid I try never to go below 80%. Yeah, I want to go to 48V LI batteries, but need the right inverters too.

Save your old system or sell it. We have some friends who saved their old system (and it's old) and they utilized it elsewhere, but they also have a farm. Aside from that; They reside in Alaska, so they used it for the chicken pen and a couple of other sections within their farm. You may make changes at your off- grid location and you know you have the backup. Or, you can sell it? Check out what other people are selling used solar array packages. Will explained how many companies are out there ripping people off. You may take a small loss, but it's worked well for you throughout the decades. You're at an advantage point either way.

I built a 12v off grid system. Works well and was still cheap. As an electrician, I didn't have to sweat wire costs. I have scraps from jobs readily available. My inverter is a 12v/120v 3500 watt. I'm fully aware of the amp potential being 292 amps. I have a PowMr 60 amp MPPT budget charge controller. I have 7, 100 watt renogy mono panels. I have 5 100 a/h Dr prepare lithium iron phosphate batteries. I have a 35 amp solar array discount. I have 5, 100 amp inline circuit breakers. On for each battery. I ran everything through a busbar panel and put a 300 amp in line circuit breaker on my inverter positive. I also put an eco worthy ammeter with a hall effect sensor in this system. I came in just under 4000 dollars. Over time of course. So far, I can't complain.

I started with 12 volts, now 24 but will likely end up with all three. 48 volt for the house mains battery bank and large inverter, 24 volts for DC appliances consider critical and needs to be separate such as pumps, lights, fans and refrigerators. A small 12 volt generator as a back up with a small battery. Something like 1500-2000 watts. 12 volts is attractive because it’s common and available.

I’ve never heard of that and it would be very interesting to see. My initial thoughts on why I don’t have a 48v you hit on: -Not very familiar with 48v -Have 12v loads in RV -48v is higher voltage and is more dangerous than 12v which is more forgiving (in my thoughts). -DC to DC charging from vehicle alternator (mobile application 12v initially appears to be a better option) -Already have 12v equipment like inverters & chargers that I already spent money on.

For 48V you can get a buck converter which has decent efficiency for lowering 48V to 12V. However a secondary 48V alternator is not that cheap to buy and install. Also it lowers your mpg a bit. Frankly if you want more power and your vehicle and array isn’t that big a 24V system is fine. Just the parts are harder to come by in an emergency.

Same with the alternator. Do I want an 48V alternator? I have no idea how to charge the trucks starter battery with this. Another buck converter? So - no.

The best solar decision I made was listening to Will. His channel has been my guiding light - lol. My story validates everything he says. When I put my system together a few years ago, 48V parts were scarce and out of stock. I wanted to go 48V then but had to get something working. I went 24V as those components were common and I could get up and running B4 Winter. In process of adding a 48V system currently. Weather has slowed install. I had to get MUCH bigger wire for battery. For the tech heads Current System, I got the discrete 24V parts Will recommended: Dual EPever BN4215 MPPT and a Giandel 4K inverter plus 6 Renogy 320W panels in 2 x 3S . Initially, 5.1KW 16 Fortune 100 LFP 8S2P with Overkill BMS. Upgraded battery to 14.3 KW 16 EVE 280A 8S2P w/ JK BMS last spring. Big difference! Get an active balancer if using the big batteries. Adding: 14.2KW EG4 PowerPro and existing 3 yr old LV6548. 12 390W Panels in 2x 6S Wire came with battery and inverter and is sufficient.

So whether you go 12v or 48v really depends on what your primary consumption is. Unless you're doing electric propulsion, there are a lot of good reasons to go 12v in the marine environment. This is largely because your critical consumers are also 12v. Your VHF, your instrumentation (GPS, speed sensor, depth sounder, wind sensor, etc...) , your engine start, refrigeration, autopilot, lighting (including safety critical things like navigational lighting) and pretty much everything else is all built for 12v nominal. When sticking with a 12v system, all those loads are directly powered by the battery. If you go with a 48VDC system, you need to add a DC:DC converter to the chain to supply the 12V to those safety critical loads. Also, alternator configurations for 48VDC are... interesting to say the least. The other reason is that Victron doesn't yet make a boost solar controller, and it is so nice having all your components (Inverter, solar controllers, alternator, and BMS all integrated and talking to each other via the Cerbo. It's a set and forget system.
@Nick-im3sm7 ай бұрын
Another easy/probably cheapest way to set up in vehicle charging in my opinion, is a 400-600w HF (Giandel is fantastic for the $$ as you said!) 12v inverter to AC charge your 48v like you would at home. Not the most efficient, but I tell people to do that vs buy those rather expensive and cumbersome 12v to 48v DC-DC chargers (I forget the name.. but they're NOT cheap and take a ton of power to run. Like 70 amps! Most alternators can't handle this) or to do 12v/12v DC-DC 20-40a and have to deal with the handicaps a 12v system has. A 48v alternator however, is also a great idea. Most efficient way by far to accomplish this scenario and get the bonus of 48v and one I haven't seen much of as of yet, but I assume it's a growing market.

While I agree that 48v is much better, 12v can make sense but mostly for legacy reasons. My boat for instance already has all the wiring for 12v, as well as multiple 12v pumps, tv, fridge, lighting, chargers, engine etc. 48v accessories are far less common, and often not available, and everything would be very expensive to change. You can step down of course, but it's just extra expense. It's the same reason vehicle manufactures have stuck with 12v for so long. The 12v ecosystem already exists for all the components , the 48v one doesn't.

For me I am full-time in my rv with access to full 30a shore power. I am looking to reduce consumption an have been looking into a 12v system purely to run the 12v service in my rv. No inverters, just purely 12v. I did an experiment recently and by shutting off my converter and running off battery only, I installed a shunt and was just trying to measure actual consumption / output purely from the battery. For the duration of the test period, I averaged 1.1 kwh / day from the battery vs an average of 2.6 kwh / day when running the 12v off the converter. So I'm looking at moving ahead with 200ah lithium battery, that's double daily average requirement, a 400 or 600 watt array to keep it charged, with an AC / DC lithium charger as backup to the solar but open to recommendations for this system.

Having 120v power to some house outlets would be ‘nice’ I saw the MPP 1000w all in one being a great fit. MPPT Charger, LiFePO charger, inverter, UPS…. Running with 1 100Ah BT battery. Add some used Santan used panels and can be done for $1500. For a 48v system I see higher cost (about 2x-3x), plus another system to ‘start’ the Generator. The Gandahl and a battery, is an alt, but then you add a transfer switch and an MPPT then your is at the price of the MPP. Am I missing something ??

I have been using 12 volts for many years and will continue to do so as many of my appliances are 12 volts. It suits my needs and has done since 1985. I use Trojan RT 104 golf cart batteries and a 2000 watt inverter. In Australia the sun is continuous and free. Maybe different over there but i love my little cabin and my Off grid system.

I'm an old telecomm guy so, yeah, I'm very familiar with 48V stationary systems. I'm now building out my dream camper van and now you have me intrigued about doing a 48V mobile system...

Just received my Epoch 300 Ah battery which when charged up it's indicating 410 Ah capacity on my Victron Solar Controller. I'll be ordering a second one shortly.

Just a heads up. The Victron Smartsolar 100/30 and 100/50 models only supports 12v and 24v battery systems, so if you want to upgrade to 48v in the future I'd go for the Smartsolar 100/20 or 150/35 instead depending on your needs

Thanks will the 12V system giandell was the one i was eyeing up. This video will help me do my own system

I use 12 for the HAM radios. A lot of street cred for that too. A voltage converter would likely add noise. I think I will have to do two separate systems, but 48 is on my radar.
