Hi Dave. @dnknecht I decided to install 35v (because it will be more longer to die) but it’s my theory. Now I have your proof. Thanks for your comment! 
Regarding soldering: So you didn’t removed old one cap’s legs and just cut the legs 
so in such case I don’t need to dissasemble all 100500 wiring harness and electronic board itself. Do I need to make the new cap legs shorter? Or cap legs length is not a case? I’m a newbie in such things like capacitors 
Dear community, my SOC is dropping zero for a couple of minutes (see the screenshot). But grid is stable and connected! I teared down my AC300 and capacitor was bad (same as on the picture in previous post)
The interesting thing- I have another AC300 new (capacitor is good!) but problem the same!!! What a h…! Batteries are good
FW is not a case (2 AC300 has different fw)
@BLUETTI_CARE hope you have some idea
