As to the issue of wire size. 

Isn’t really that the OEM's want a specific maximum resistance of the wire 
between the multiple inverters and batteries for that matter?

I am reminded of a project I did 1.5 yrs ago with 10 Fortress Evault max and 3 
inverters.   Of course fortress wanted equal wire lengths between the batteries 
to the combiner.  
Given the number of them, and the layout it was going to take about $3000+ more 
in wire and where to put all that wire.
I thought about it, and came to the realization that they really just wanted 
equal VD between them.  I did the calculations based on max load/charge split 
between the batteries  and ran the numbers by their senior tech/engineering 
staff, they agreed.  Basically in short, closest battery had 1/0, then they 
worked up to 4/0 at the end.  All the VD between them was about .5% which they 
approved. This saved me and the client a ton of money and a huge hassle over 
where to actually store all that wire. 

This issue with inverter cables needing to be the same length is the same 
thing.  They don’t have to be the same length they have to have a similar VD 
between them.  What is that number supposed to be?  We are engineers or play at 
being engineers, tell us what we need to know.  Do we need to buy a resistance 
tester to confirm the wires meet a specific standard?
All wires are not the same.  What if Im using two different brands/ratings  of 
4/0 because I ran out or my supplier ran out.  How am I supposed to know?

When I look at the old Trace manual, yes I have them still of the SW 4024, they 
at least had X wire size for Y distance and then different sizes for longer 
distances.  Midnight just has 4/0.  Luxpower has numerous combinations of wire 
sizes per distance.    But I would like to know what am I supposed to be aiming 
for? .5% VD at rated power? Or is it peak power or? Or some actual resistance 
measurement or? or what is it? If I know what its supposed to be then I can mix 
and match wire sizes to get the correct % VD.



Don’t just tell me 4/0.
