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...

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

Ive never ran into issue installing loadcenters "upside down" same codes still apply no more than 6'6" to highest breaker. You CANNOT however feed a passthrough panel from the lugs connected to the busbars. Your incoming power ABSOLUTELY must terminate at the main breaker.

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...

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...

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.

Looking for yalls input on using this ISDT Q8 for top charging my bank, i originally purchased it years ago to charge my lipo drone batteries though as you can see it has life settings, i know its probably not ideal but will do up to 20amps with a proper power supply, currently using a laptop...

Its still L1 of the growatt

Thanks for the reply, i did feel a bit daft asking but ya never know

Got a pic of batt wiring?

Just a quick battery box question..ive never seen one, ive never assembled one. I have this aluminum case that was previously used to ship wine bottles in(from tiger woods FL house, the one he lost in the divorce. Was a really nice house.) It fits my bank nicely with room for insulation and the...

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

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...

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

Maybe. But his isnt.

Bet ya didnt see that mny problem lol @timselectric

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.

Sucks when parts dry up. While the genset maybe no good anymore it sounds like you still have a good engine for other projects or salvage generators.

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...

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...

Basic layout, have a piece of plastic lining the bottom, insulaters at the ends and between each cell, still waiting on bms to arrive. inverter was a gift from an old employer if you were curious about the selection lol

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!

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

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

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.
