I am so stupid. I had the biggest brainfart. In all of my trying to figure out wire and circuit breaker sizes, I'd forgotten series compounds the voltage and parallel is the opposite.
Nothing about any of this is particularly difficult, it seems, however there's just a lot to keep track of and...
I am planning on building a small (~1.2kwh) mobile system that can be hauled around the home and yard for various AC applications. I do not have any needs for 12V DC output at the moment.
I would like some feedback regarding this diagram, as I'm a complete beginner. I have been reading and...
1.25x wire rating, not max load? Just making sure.
I'm assuming I'll need an appropriately upsized cable (0 AWG) as well to accommodate the efficiency?
Thank you for the information!
That appears to be exactly what I need, but I still can't find a way to "add to cart" on that item. Does that website not actually SELL the circuit breakers? I'm appreciative that it lists a price, but I don't see where to click to actually BUY IT.
EDIT: Is this normal? Needing to buy shit to...
100w/12v * 1.2 = 10a
2 of them = 20a
I know in realistic conditions panels will not pull their maximum rate the majority of the time, but don't you need to spec your system to theoretical maximums to be safe?
I'm really just trying to find the smallest, reliable controller possible (with a...
I thought I had already done that. Did I do it wrong? This is what I used:
600W / 48V = 12.5A
12.5A * 1.5 = 18.75A, rounded up for 20A DC-rated MCB
1200W / 48V = 25A
25A * 1.5 = 37.5A, rounded up for 40A DC-rated MCB (EDIT: See below realization, I think I'll need 70A DC-rated MCB)
Will do...
I'm planning on having this be a small mobile system. Everything will be very close together.
Gotcha.
How does one tell? Is it on the breaker itself? Or will it be in the specs on the manufacturer's website?
Interesting! I will look into this.
I'm having trouble finding the distinction in any documentation.
I've been looking at CHINT and NADER brand DC MCBs, specifically, because that's what I've been seeing coming pre-installed with some of these server rack batteries. If I'm not mistaken, I think a NADER MCB comes installed on...
I do not, unfortunately. I abandoned my idea for a 12V system and am planning on using 48V. I have a separate post with a different, updated schematic on that post if you'd like to take a gander.
Okay, I'm sorry for all the questions, but where the fuck can I actually buy these things?
It seems like the only MCBs that are readily available are ones that are popular DC-rated MCBs or just any random AC-rated MCB. I can find product specifications, but I can't find an actual SELLER.
I'm...
I posted a schematic a couple of weeks ago and received some feedback. I've since made some adjustments and would like some feedback on this new one.
Basically I just want a little mobile power station that can power some stuff around the house and yard. Nothing crazy, maybe some fans and a...
