now-stolen Epever 40 amp controller had terminals that fit #6 with room to spare

Yeah I do love mine they sure have the wire terminals figured out nice and beefy.  Really nice having RS485 with lots of plug in options.  Sorry yours got stolen.

Looking at forecasts prices for copper and aluminum looks like they will be going up fast.  That does not sound good.  I may grab some copper stock in Robinhood.

Yes, 4 identical breakers riveted together that have a spindle between them to trip them all simultaneously. It isn't just a handle tie. As far as MakeSkyBlue, who knows why the Chinese do what they do. I never owned one, but my now-stolen Epever 40 amp controller had terminals that fit #6 with room to spare. I have a bunch of wire pin reducers that I use when the wire is too big for the terminal that I would crimp on otherwise I suppose.

The 6-2 MC from the wholesale, the THHN from Home Desperate, which, unless you're buying thousands of feet, has the best small wire prices. The wholesale can't touch it below 10000 feet. Loss leader etc. You've got some great pricing in these times of skyrocketing materials, or you're buying a chit ton of it. What's lumber cost for you?

No, I just buy from the local electrical supplier as they have always given me good service/prices. I will say that if I wanted a job down here right now, they have help wanted posters up for the 3 biggest electrical contractors in the area as there are not enough people for the jobs at hand. The owner of one was in there when I was getting supplies because he could not afford to have anyone leave the job sites. I could likely pull in enough to double my current retirement income, as just a helper/apprentice. But boy would the taxes eat me alive.

Same applies to the welding cable I use. Local supplier sells it cheaper than many on the web. But then they have it in large spools which may hold 1000 feet of 2/0 cable.

Lumber, way too much. What was a $35 sheet of plywood is now $65. But it is easier to find better quality wood as nobody wants to buy at those prices.

How mucyh is that welding cable ?  just for 20 foot is like over 100 bucks for a black and red wire. geesh.  I want to redo my whole system in heavey wire, I got some 0/3 or something like that is big, and was used to handle over 600a 12v for my boix truck, but I don't have enough of it to wire up all my battery bank together, only enough to run it from a bus bar to the inverter. useing 10 awg I think right now for 24v 100a. I reather have bigger wire to go directly to the inverter instead of a dang bar.

The thing that is so stupid, is the bms that on the market mainly use 10 awg cable for a 100a unless its more then that then the3y use two 10 awg.

2/0 was $2.50 a ft.

Hey Sid, any luck on the latest update?  Also I need to know if we still going to stick with two wire per phase or that needs to change.  I got a eletrical guy coming in if need to change it tomorrow.  Thanks

Waiting on Sean to test the code for now.

But as to which method to use, I'm waiting for your final decision:

  • We can stick with the original method discussed (parallel "daisy")...but that's going to have to wait until the code is tested and deemed at least passable.
  • Or we can set both inverters up in single-phase mode (sync 180 degrees apart), with each inverter running one phase in your panel...and ship 'em out in a day or so.

Okay, had my guy come and finish up the breaker box for me.  I got two 30a double breakers, there was no 25a.  both wired with 7.6 of 3/10 through a conduent for each line.  one wire with black for L1, red for l2 white for N both of them wired that way in the breaker, ran out form the bottem then right into the next area where the inverters will be.  Dang just those breakers and wire was over $100 bucks geesh.Any how, foudn out my breaker is a square D with some weird clamps that looks like the type that goes onto dim rails.

So any luck with the latest test?  I see sean posted pulling the plug deal. . .  Also Sid do these GS inverts have a 120v outlet by chance on them?

Yes, the GS inverters have 2 120v outlets on them, one for each phase, separately fused with a 15A breaker.

Don't think any parallel tests have been done on Sean's bench lately.

Jumping up and down, Looks like I'll be getting my Pups next week.  I'm so excited, I could bust a move.  . . .Already getting ready to do some solar upgrade maybe this weekend.  Will be slowly adding more load to the inverters, while keeping a eye on the battery system.  such as no water heater and aC to begin with.  Got to make sure all my battery making holds up to the amprage with no issue :P.  also make sure the copper bars can handle the amps as well.
