I see, I hadn't thought of the grub screw as just a mechanical fastener. Explains why I saw another person in a different thread saying they were using JB Weld to fix stripped threads. Thanks for the quick responses!

Gotchya, so this is a particularly beneficial option if you already have existing infrastructure / a microgrid setup / a Tesla powerwall / etc. which already produces AC. I see, I hadn't even considered that these would be "smart" on the AC following side. In hindsight, that makes obvious...

I see. So, if I am understanding correctly, it seems like the regulatory concern is mostly about ability to backfeed the grid? Does this imply that, in an AC coupled system, the AC coming off of the panel inverter(s) can "see" the grid AC and vice-versa, hence the regulatory regulatory...

Hello all, First time posting here, been lurking and learning. I am a bit confused about when AC vs. DC coupling is better for a given setup. From what I have read so far, this coupling refers to the mode of energy ingress to the primary inverter from a battery backup or similar, either AC or...

Hello everyone, The question is simple but I am getting conflicting data from SAM. In short, how much space do I *actually* need on my roof for solar panels for an 8 - 10kW system (still haggling with myself on the exact system details)? To figure this (and many other things) out, I...

Hello all. While reading though the resources section, particularly "Rules of Thumb for Terminal Posts", I see that Red Loctite + primer is often recommended to secure stainless grub screws to the delicate aluminum sockets on many batteries. This seems like a sensible mechanical precaution to...
