I started with solar watching videos, but also kind of winging it and figuring stuff out. Your comment caught my interest, because I just now after 2 years installed 8 100w solar panels and I have 4 100ah LiFePo4 batteries for my travel trailer. I have a Renogy 100w MPPT controller, a 3500 w pure sine waver inverter and used the setup from Will Prowse? I believe. Seems you have about 1000w more solar power than I do. How happy are you with your setup, and the balance of solar wattage vs battery size? Any advice?

After using 12v Li batterys for 5 years and if I had to do it again I would switch to 48v. And just use one 12v Lithium battery to run the 12v house side. The 48v would just be to make 120v AC. Then I could run everything, even our roof A/C's without all the stress on the components. Yes, the copper is a bit cheaper, and the other components may cost more, but that huge high amperage needed to make AC from 12v is problematic.

A 32s bms would be a custom build and not many devices work with 96v dc yet... Maybe one day it will make more sense, 48v is the leader right now 👍

NONSENSE ABOUT WIRES. PEOPLE JUST BUY TOOOO THICK WIRES. I TRIED MANY TIMES HIGH CURRENTS WITH 2X THINER CABLES AND ALL WAS OK, THERE WERE NO HEAT. 100AMPS IS NOT A LOT! But yes 24-48v systems are better. 48 not that much, unless you have HUUGE capacities. and you drawing 2kw and more constantly.

The amount of cells in series for high voltage batteries becomes problematic to manage and expensive, like Tesla who uses very high voltage packs.... 48v is already 16 cells, its affordable and effective enough for most applications.

48v doesnt need wires as thick cus the amps needed to get the same watt output is way lower more effecient less heat loss! 12v high amps require much thicker wires!

Haha, thanks for your comment! 120v DC is too many batteries in series to manage for most systems. Let alone large AC converters required. 48v is 16 cells in series already, pretty solid balance of power and efficiency, which is why any large system is 48v dc. You can run off that directly, or step it up or down without too much loss.

You can wire 4x 12v batteries in parallel or in series... Series 100a 48v is the same watt hours as parallel 400ah 12v. You get the same amount of watts either way, but on 48v you get to use those watts more efficiently.

Only two people using and when running longer (watering grass,shower and such can use generator. Would like to get Eg4 air conditioner/heater or something similar. Also got the echo tracker, have 8 solor panels 195w but the most I get is 120w I bought a velvor 3500w inverter but it's 12v can return it? Was going to make a 400ah 12v with bats, but thinking I should Make 48v 100ah instead. Living in RV trailer fixing up old house. Figured time I connect to grid. Rewire House, cheaper to go solor. Was looking at the Eg4 all in One instead of the velvor 3500w inverter? What's your advice? Will doesn't reply to famous. Lol why I like smaller channels.

48V kills the capacity While 12v has 4 times the capacity It's a one time cost Soo i'd rather stick to the 12V with the Huge cap instead of cheaping out on the wires and having the 1/4th of the cap + The 12v u can charge directly from ur car/truck/solar pannels

I'm not sure what you mean, whatever you are powering eats WATTS. And, a 12v 400ah battery has the same amount of watt hours (the amount of hours you can run 1 watt) as a 48v 100ah battery bank.. The formula is: Volts * Amp Hours = Watt hours. 48v will store and power devices more efficiently.. That why any system over say, 2000w would be better to go 48v, over 12v. There is no question.. that's why almost every large home solar battery bank runs at 48v. Check out some Will Prowse for more details!

@@RamyFalyou lose power with lower voltages over distance. To avoid power loss with 12v you need thicker copper, it isn't just about the amp/heat rating. Have you even looked at power loss over distance charts for copper wires for 12v vs 48v? 12v is very inefficient - you can just buy a step down from 48V to 12V for your 12v devices

Lol thanks for your comment, but your math may need some double checking... Look at watt hours of the batteries and add them together... 48v is pretty close to the same price as 12v in terms of wh and a lot more efficient in copper and electronics. Watts are what you use in the end, not volts and amps. It's important to know v*ah=wh. Do I get the clever award back?!? 😁

I agree to appoint😮 Each voltage has its place for efficiency and usage. If you’re in an RV all your appliances built-in are 12 V so don’t try to reinvent the wheel in an RV. If you’re building out a new rig 24 V is the way to go to either step down to 12 V for those few things you may need like lighting water pumps And so on. yes, I would agree 1000% if you’re on land and building an off grid homestead 😊a 48 Volt system is 😮 a no-brainer.😊
