hay people just joined here, new to this trying to learn but guess I am not that smart. what would be the different between 12 and 24 volt the advantage of it. trying to figure out what I want will go for the starter kit off grid but just having a real hard time trying to know what I need. just want to power fans, ref, lights, but any how hi there hope to learn here have tried all the others and got no where

I'd go 24v if you can swing the extra cost.....
What's in the starter kit that your looking at???

If you appliances are all 12v then go 12v on the batter side.
On the input side, if you get mppt then you can use 12v panles, 24v panels etc.
If all your stuff is 120v then you;d need to a find a 24v inverter if you go 24v.

Choosing between 12V and 24V solar systems comes down to your desired energy consumption. Theoretically, 1000W is about 83Amps on a 12V system, whereas 2000W is about 83 Amps in a 24V system. The higher the amps means you need higher rated components so you're not constantly running high amp loads continuously. We would recommend tallying up all your desired appliances wattages and as well as a more or less figure for how may hours a day you would roughly use the electronics. This would give a better estimate for what kind of system is beneficial for you.

Yes sir that's why I asked what they are planning on running before making the decision on what to buy...

thanks all I forget it takes a lot of information on solar to find out what you my need. ok let me as one thing if you go on the grid you don't need battery's you just connect straight to the meter don't you. so if I wanted to do this could I just run all my stuff to it's own master breaker and run my run offs from there with out battery's I just don't understand this it is so hard to figure out . I guess I am just going to buy a 24 volt small system and experiment with it ..

My cabin is totally off grid and I love it.... Yes you don't need batteries to be on the grid with panels..... But I don't understand why you would want a solar system that when the power is down and it's dark outside you don't have power just like your neighbors.... That escapes me.... Why not build a system that never goes down? Riddle me that Batman...

Agreed.
The easiest way to wrap your head around it is to consider the panels to be a giant battery charger.
And congrats for getting off the grid tattoo.
Offgrid question: Say you wanted to run a woodworking shop or a welding fabricaction shop, is that where the 24v would be more beneficial?

Or even larger... The closer you can get to 120v the better it will work...
But with that said the more everything cost...

ok got it so you can run it on grid but the battery's are just the back up for when the sun goes down and your panels are not sending a charge dam about time some one told me the right way thanks a lot. the reason I just want to lower my electric bill and not to be completely depend on my electric company but thanks a lot for clearing it up. now I will start on my build going 24 volt I hope any how

Good luck....

ok what I am going to run is a house fan refreg. lights, tv computer nothing big that's just about all that runs in the day time like I said I really don't know nothing about this and can't seen to wrap my head around it I guess i'll have to buy and experiment with it at les I can't blow anything up trying it..

Seriously though, if you have time and money to experiment with, a good learning project would be to build yourself a portable solar generator.
Aside from aiding in the understanding of how the system works, you will be developing wiring skills, crimping, soldering etc etc.
