bor How do you calculate this? The 2 AWG cable is very thick,According to the cable size calculation formula, 12mm or 16mm cable size is quite sufficient. This means 6 or 7 AWG in the American system.= [1* (1000/12)+25% *2 *0.0178]/(12*0.03) =10.30 mm => cable 12mmis sufficient = 7 AWG ( 2AWG = 50mm !!)
2AWG is 35mm². I showed you how i calculate it in the video, i use the NEC table for current capacity. You formula is a voltage drop calculation, not how you size wires. It also depends on the wire temperature rating, here i have chosen for a 90°C insulation temperature. If you use welding cable, you can use 4AWg or 25mm². Check my full video on how to size wires.
@@cleversolarpower you should clarify that in your video because many people don’t use the cables that come with the inverter because they’re too short. Many people think that the thickness is all that matters and your video continues that misconception.
Good info.
Glad it was helpful!

so also make sure you use wire rated for 90C, etc...
Indeed! It's described in the full video.
If the current for a setup is 214amp will 220amp fuse be ok ?
No, multiply with 1.25 and that will be your minimum fuse size. Then size a wire over the fuse size.
Where did 125 came from? Why to multiply the83A with 125?
1.25 is standard safety factor according to nec
@@cleversolarpower ❤️👍🏻 Thank you.
How big can be voltage drop
Infinity in theory. But should be limited to 3%.
@@cleversolarpower thank you for answer. Are you electrical engineer
What is the distance of the cable needs to be 100 feet, you didn’t discuss the distance.
Inverter cables are short, so no need for a calculation. We only apply voltage drop calculations for solar panel wiring. Video coming soon.

I have a 8.2Kw inverter that is 48v. I don't see 213A on the table.
