Many of us now with the lithiums are able to do things that are still taboo in the eyes of the old techos living back in the swaggy days where they had their broom handle over their shoulder and all their belongings in a scarf.
Soon what we are doing will be available to all. Only needs us to wait the 5 years they wanted so, the many people who have now taken to the technology can have the fun first.

And the old school mob STILL understand that you need the charging capacity to replace what you use
No matter what the battery type

Hopefully will be heavy enough. supposed to be good for 250amps continuous
Shitte, is that the diameter or the radius 85mm sq is 4/0awg and 107mmsq is 4/0awg, so 95mmsq must be somewhere inbetween[
heres the link http://www.evworks.com.au/index.php?product=ZDU95O
295 amps continuous
95mm2 if that makes any sense
HI
Yes it makes sense
95mm2 is a litttle larger than B&S000 & a little smaller than B&S 0000
Plenty large enough from both voltage drop & required current capacity
Voltage drop @ max current = per mt run length= 2mts x 250A x.0164/95=0.08V
Rated continious current of 295A gels as it is between
262A for B&S 000 & 302A for B&S0000
I would suggest that the 19.5mm is o/a dia of cable PLUS insulation [

Just not straight away or the following day, they don't care if they never reach 100% recharged, yet they will accept 100% of the charge current offered till they are fully charged, that's the part many seem to have difficulty understanding or coming to terms with, all the solar current goes into the battery, not just some of it

Still, with a continuous rating of 295amps it will do just fine 3000w divided by 13v = 230 amps, plus 10% = 253 amps, the inverter can't pull a continuous load greater than that so you have a bit up your sleeve.
Just measured for you especially
the 14mm and 20 mm are correct
So I guess the 95sq is wrong and I have bigger bang for my buck
Shouldn't be an issue for overheating, and if I break a spring again I should be able to disconnect the leads and weld
BTW, for those in the west, EV Works were very helpful and competitive. I didn't need to buy a crimper, its all done for me

Actually, at 24v or higher you can weld like an ordinary stick welder with very little voltage sag. This does have a down side, short circuits are big, a fuse near the battery is a must

Hi
Actually it is a metric size cable to AUS standards, not B&S or AWG
95mm2 metric cable rated @ 262A continous

Hi
The fuse is sized is to suit either the MAX load current or the max cable rating ,WHICHEVER IS THE LEAST!!
BUt as ALWAYS should be fused as near as practical to the battery
85mm sq is 4/0awg and 107mmsq is 4/0awg, so 95mmsq must be somewhere inbetween[
