Are you building a 12v system?

I agree that's what I think of when I see darker copper. @12VoltInstalls may be right that it's the rubber jacket of the windynation wire that is breathable and allowing the oxidation. I'm not gonna be using these wires anymore so I won't bother wire brushing them and making a mess of copper dust.

The Inkbird is the obvious suspect. Freezers and their control logic expect to be powered 24/7.

Oh I use the lightbulb to drain + and - on the battery terminals. I don't think my inverter would let anything out the AC side when it's off. But I've never tried.

Yup, works good on mine.

On my XW yes, the caps will shock you with 48V.

I like the Temco PV wire. But I only use it at the array. THHN in conduit for the rest of it.

I hadn't heard that about the V3 but idk.

280 V3 with the octagon terminal is good, but I haven't really followed the MB30/31 news.

That would concern me for a different reason... That my dentist might be eruopean.

I would be concerned if my dentist was running on an inverter and it wasn't a Schneider XW.

Pools are another one that creates second earthing points. Don't worry about it, just make one intentional grounding point. The electrons will respect the intentionality and go there.

I thought it was a year after applications and the window is closed now.

Good catch! I missed that. Not even a tariff increase for us now. Unless our cells get automatically considered EV batteries or something. I could see that being true where they mean like power tool batteries get the tariff in 2026 but big Lifepo4 cells are already considered an "EV type" battery.

Or wait, just manually disqualify grid? It already has contactors in the XW for this. No need to duplicate the functionality.
