It might be the DC side as well. Are you using 24v or 48v? Even if it's 48v, if you have bad connections or if one battery has substantially less resistance you could be seeing problems with your batteries.
Be sure to check all the connections under load.
I just went the grub screw and flange nut route. 15mm worked for me, but barely. 20mm would have been better.
I added red loctite so I could torque the nuts. Buy the inactive metal variant. I went with what was on the shelf and they slipped a bit. Someone on here recommended taping the...
This looks like a pretty good deal. The footprint is a bit bigger than what I'm looking for, but the other numbers looks pretty good.

How are you hooking up the 1000a inverter? I would assume that's some serious cabling there.
That's why i'm suggesting a stud vs. a busbar. You can connect everything to a central point(the stud) that is sized for the combined load and distribute with cabling according to specific load. Each...

Here are some spec sheets for the cells I used. I'm still not entirely sure on the max c discharge rate, but I suspect it's more about cell life than delivery.
For 28v you could probably do 11s and as...

There is a thread on how to install the grub screws. Use loctite on the screws and torque the nuts to spec.
That dc airco one looks sketchy. There are a few on ebay that might come from the us, but probably not. Honestly, I think getting them from the source is the only way to go right now.
I like the mini split wall mount vs. the ceiling mount. I think we can them cheaper than the treeger on...
Anyone have a comparison? They both seem to have their downfalls.
Concerns with the MPP:
145v Voc PV input / MPPT with MPPT at 60v - 115v
60a Utility charger
Only 70lbs
Concerns with the Growatt:
Can't be parralleled
Single CC @ 5kw total
requires battery
I have 10 panels @ 50.4Voc...
