Howdy,

I'm in the process of trying to figure out how to get all my wiring for my van build/conversion set up, so I thought I'd pop over here and ask for help. Just wanted someone to take a look at my wiring diagram, and give me some advice on what else I should do/not do.

206Ah LIFEPO batteries: https://www.sokbattery.com/products/12v-206ah-lifepo4-lithium-iron-phosphate-battery-pack
Solar panels: https://store.santansolar.com/product/rec-325w/
Renogy 40 Amp SCC: https://amzn.to/3n8k9Gs
GoWISE 3K Inverter: https://amzn.to/3kS6256
DC Fuse Box: https://amzn.to/2WVS1uU
Victron 500A Shunt: https://www.altestore.com/store/met...attery-shunts-p41526/?afmc=29#VICSMRTSHUNT500

Products of what I'm planning on using are above (in the case there is something that I missed, like volts or amps or watts for something).

I'm planning on using 4AWG (is that's the right term? 4 Gauge wire) on most every major wiring - hooking the Batteries together will be 2AWG wire, and Solar panels and shunt, and appliances, will be their own respective gauge wire.

I went with a 40 amp SCC because I read that they can handle a higher input, they just don't output anything higher than 40 amps (Clarification on this issue would be appreciated. Also I'm not opposed to having 2 40 amp SCC's I just need clarification/direction on how to wire them together/into the system together.)

I'm also looking for advice on whether I need more fuses/breakers between different connections (Also links/direction to where I can find said products). I read that it's good to have a shut off between the Solar Panels and the SCC, but didn't find what to use for that.

Like probably many people here, I'm a complete newbie at this, so apologies for any questions that may seem idiotic to answer and if I asked too many. But I'll appreciate any help what-so-ever, so that I do this correctly the first time, and not lose 'life, limb, or eyesight' in the future.

Thanks,

Andrew

Fuse the cable feeding the fuse box suitable for the cable rating.
If running the inverter at full 3000 watts it will take 250 amps. Needs suitable cable, increase fuse to 300 amps.
The shunt is wired incorrectly, all negatives to the output side of the shunt, except the battery negative.

use this chart for cable size, you need serious cable for the inverter and battery interconnections. Do you really need a 3000 watt inverter?
An alternative would be to consider a 24 volt system with a 24 to 12 dc converter for the 12v stuff.
