    critique my design?

    Very helpful. thanks. So in my diagram, if I add a 1AWG cable from the (-) block to a good clean chassis ground, that should be fine, and it would be the only location that's grounded to the chassis, correct? All other negatives (or case grounding terminals) would just run into my (-) block.

    critique my design?

    I was under the impression (perhaps incorrectly) that the built-in BMS on these batteries would take care of that. I'm planning on these batteries - SOK 206AH - please let me know if you think I"m missing something here.

    critique my design?

    Hey everyone, thanks again for the help. I've made some more progress - but could someone explain how I should connect the negatives to the chassis? I'm not planning on having any shore-power at all. And planning on running the negatives for each appliance/load all the way back to negative bus...

    critique my design?

    oops - applied my labels incorrectly :rolleyes: I'll delete that old image, and here's the corrected one. For the water heater setup, it's basically running the main power for the water heater through a relay, that's controlled by a 3-position switch.Option one is "bypass" and it's just the...

    critique my design?

    Okay, did a bunch of updates, switched as much as i could to 24v, and changed the hot water system, so it automatically comes on when the batteries are fully charged, but has an over ride switch for when I need it even if batteries aren't charged. <<image removed, see post #23 below for...

    critique my design?

    my alternative I'm considering, which might make more sense, is to purchase a 2.5 gallon Rheem water heater, and swap in a 24v 600w heating element. I'd like to figure out how to have it automatically heat only when the batteries are full (with an override for when I need hot water, even when...

    critique my design?

    I'm wondering if it's even worth setting this up as a 24v system though - do the advantages get wiped out by the losses on the 24/12v converter? Or is it worth it to keep it 24v, and just see what items I can actually run off 24v directly, and minimize what I'm going to have to use 12v for.

    critique my design?

    oh, and this is the water heater I was going to try. It's just 1.5 gallons - but if we set it to 150 degree f, that means mixing with water that is at about 60 degrees, we should be able to end up with about 3.5 gallons of nice temp water, around 100f. This is mostly for washing dishes, although...

    critique my design?

    thanks for that insight. I'd rather build it to handle any eventual situation, so I'll bump up the wiring gauge. Are my 200amp fuse and breaker okay? I'm assuming my 1 AWG for the negative distribution block would still be okay? As the negative to the inverter is separate, and I'll bump that up...

    for the image? Adobe Illustrator.

    critique my design?

    I totally wanted to...but ran into a couple of roadblocks (like water heater - I've only found a single 12v water heater, and no 24v ones, or the Maxxair fan), and decided I wanted to have 12v available, at which point it became somewhat pointless to have another bank of 24v appliances. Planning...

    critique my design?

    Super helpful!! Thanks so much. I updated the drawing, taking all of that into account. My panels I had picked were out of stock now, so I swapped them for some slightly larger ones. Not sure which ones I'll actually end up with, probably won't order for another few months, but in any case...

    critique my design?

    Working on a design for a truck camper I'm building in the spring - this is my first real system, beyond just using a goal-zero, or slapping a single panel on top of my SUV with a PWM controller. I'm planning on a 24v system. I think I have all the info needed to critique it on here, but let me...
