Yes it is, also that isn't my picture, I stole it from Will's 24v blueprints.

Would 250a be enough?

Ok, my SCC are a total of 100a ( there are two of them). The DC to DC is a 40a.

So I was basing my design from this, which is on Will's site. I have what says Main Fuse and I'm trying to see if I need a bigger bus bar. Sorry if my lack of terminology is confusing and making this more complicated.

it is 3000 watts and I have a positive fuse that all of my positives will be connected to.

I guess what I'm asking is what amps? I have a 24v system and just want to make sure that a bus bar of 100 amps is going to be enough,

Hello everyone! I have a question! How do I size my bus bar? I bought one of Amazon and didn't realize they had different sizes! Please Help!

Thank you very much! I do want to learn more, I want to be able to locate an issue that may be in my system and how to fix it as well. I appreciate all of the help!!

Thanks so much! I am definitely under the 3% drop. I am at slightly over 2%. This is awesome information! Thanks again!

I am wanting to have a 3000 watt inverter charger. Would that go up to 200 or 250? If you don't mind can you explain how to calculate this?

One more question, in his diagram he has a main fuse but how do I know what size to use? He mentions 100 amp to 300 amp and I don't know which one I am supposed to get.

Oh okay! I have two 50 amp SCCs. What size breaker would I need then?

So my system is a 24v system. My question is that Will in his site about the 2000w 24v blueprint, he states that one needs a circuit breaker between the solar charge controller and the main fuse bar. I have two solar charge controllers, do I need a bigger circuit and/or two different circuit...

Yes, you understood that correctly! The VoC is 49.86 at 24v in parallel each pair of solar panels.

Ok thanks! I am definitely going with the 24v then in a parallel connection. This helps a lot!

So now that you mention VoC, my panels do say 49.86V. Would two of them not work to a 100/50a Victron Solar Charge Controller?

Hello all, I'm a newbie so please take it easy on me as I learn. I was watching one of Will's videos over the 24v set up. I believe that that is what I will be going with. My reason for this is because I have a larger than usual set of solar panels. I have 4 405W Panels. I was planning on using...

I have calculated my electrical needs and have determined that the batteries should be more than enough. My question was regarding my solar panels and controllers and make sure that it is going to hold up. For the inverter I will need to do some math to know what exactly I need for AC and DC but...

I'm confused, once again I'm sorry because I am a noob, but what would I do for my 12v lights and other stuff?

Thanks so much! All of this is super helpful! I have not yet bought the inverter so I will plan on the 3000w and I'll also purchase a 24v to 12v converter! I was just worried I would fry my chargers with those panels!

Yes mobile. Yes flat on the roof. For batteries, I am going with 4 200ah LiFePo. So you think that with them flat on the roof, I could get away with 12v?

I have not installed anything and my questions come due to my limited knowledge of solar power. My family and I are converting a school bus into our home and I am coming close on the electrical setup. We have 4 405W Solar Panels. I have two MPPT 100/50 solar charge controllers from victron...
