Matters not anymore supervstech, this is not the place im putting my energy into. You can deltete this thread and my account.,

OOooh no....

Was wondering if anyone did load tests on batteries with 3 or more cells in parallel. I have a question /theory regarding configuration.

I dont know why i do this to my self, but here goes. This is the issue that occurs when you start start using single phase and mixing split phase/auto transformers. A neutral is basically a reference point. As you can see in each diag, each leg on the transformer that is grounded is labeled...

Save those for after the inspection for ez identification.

No worries, wont get anymore ass hattery out of me. Breaker for growatt should be (device rating in watts)÷ 240v rounded down to the next available breaker size.

Cleaner diagram is not my problem. I know how to wire this stuff. All there equipment should come with diagrams. If not there found online. I only came in this thread to help a little girl from her fathers ignorance. But theres no shortage of that knowledge. DiY solar forums doe not need another...

Id call them critiques more than corrections. As stated previously ive got no experience with the inverters or auto transformer,never seen inside there manuals to see how they were wired up,not my system,not my job. My main moivation for joining this forum was to learn something and repay that...

No i understand it all perfectly well.

Its a system installed in a north american territory. Off grid.. with no ahj, no inspections ..ill be staying out of threads and lurking. Does the forum have an obituary section i can keep an eye on? I cant believe this all came from one color selection...get real. Can yall point out...

Im aware of american standards, im also aware all european fixtures and appliances i have installed have brown and blue leads. Grounds may also have a yellow tracer

You are correct, and in that case i should have have blue and brown coming out of the growatts.

Depends on how smart he his and how good the print is lol

And after the auto transformer that is dictated, im sorry for the confusion white doesnt show up well on a white back ground. Ill be sure to not put so much effort into further posts to avoid such scrutinty over a drawing meant to assist the OP

Yes that one you posted appears to be what your looking for. ITs actually not too paid compared to what some breakers costs(10's of thousands) depening what your looking for.

Thats a main breaker...it only has 2 inputs. I did google 4 pole breaker tie and was surprised to get some hit for square d and other generic stuff but its gonna be a diy solution dont think youll find anything factory

You would be looking for something like this you could snag the bar from, to my knowledge they do not make such a device for aftermarket modifications. However they may make a quad breaker in the flavor your looking for and you could modify a bar from a 2 pole breaker to interlock all 4 handles...

It is my understanding(which could be wrong), inverters for the U.S market come split phase 120/240 wheres as his units only put out 240 hence the need for the auto transformer.

Maybe. But his isnt.

Yes, though op isnt in america and electricity isnt racist.

Its still L1 of the growatt

Someone correct me if im wrong as ive no experience with growatt inverters or interconnecting them but from my knowledge this is how it should be wired in its current config id refer to @timselectric for proper bonding to earth. fuse as needed with your 2 growwatts feeding 1 2 pole breaker, then...

While i would never try and shy anyone away from getting an inspection,as they tend to keep contractors honest, inspectors job is to make sure the work completed is up to local code, they typically do not and will not inspect to see if the equipment functions or is wired properly, in your...

My understanding on this subject is a bit different coming from a different background the neutrals job is to carry the unbalanced.load back to its source, in standard split phase system when you pull a 240v source from 2 120v legs you have a balanced circuit and there should be no load on your...

Got a pic of batt wiring?

Added 2 more 100w panels to the chicken coop so were up to the max listed 400w(on paper) for the SCC it was tight but they all fit. The renogys have a ocv of 24.3v while the new ones are 24.5, is the .2 gonna get me? Time will tell. Kinda bummed i cant check out the output since the bms is down...

Nope, id put money that he has both of the load leads coming from a single battery instead of the + coming fromthe opposite side of the bank of his - .most negative most positive. Please prove me wrong, without pics from OP though nothing is 100%. He gave a simple explanation of problem he got a...

When wired properly both of the batteries should see a 2a draw. Youre wired improperly.

Personally even with paralell circuits i dont terminate on 1 battery and prefer to have them terminate on each end cell, distance matters with DC since you are effectively doubling the length compared to an AC circuit

Ordered a 4s-8s JK BMS with 2amp balance, not exactly what i was hoping for but it will hold me over until im at 12s and will be able to use it else where once this bank gets large. Since beginning this top balance process i have developed a new respect for just how much it takes to fill up...

Well i was finally able to get that bank of batteries charged and noticed the bms allowed cell #2 to reach 3.7+v with a high volt cut off set at 3.6, so the daly is getting returned and am in the market for a new bms, which is ok since ive got some time doing a top balance after i had tested the...

That may be the biggest issue he has though it is not the only. Auto Xfmr still not bonded i can for sure see that. Nor is that how i would prefer to see the disconnects wired. BUT... this is DIY so long as it works!

Bet ya didnt see that mny problem lol @timselectric

This is a very specific niche in the electrical industry, I attended a trade highschool in CT so ive been electrical work since i was a teenager, i am now 40 yrs old, lost a year here and there in 2008 and a year in the .MiL, but the rest is all high end homes, lighting control, generators...

Im of the opinion that it is a completely resonable statement givin the circumstances, ive smacked an old lady who was about to touch a live buss bar. Id bet hed rather have hurt feelings and bruised ego than a dead wife/daughter
