That's true. There may be gotchas overlooked that even those who know what they're doing may miss. The only danger of using plug type disconnect on DC is arcing during disconnection under load and incomplete plug insertion creating loose connection and fire risk. Blade or knife type spring actuated lever disconnect is safer but is more expensive.
By putting it in the specs for the part.
Still required at the inverter.
I have these all over my installation i.e. solar pv feed in , battery feeds to inverters etc. To qualify ‘ unless in a case of emergency ‘ , that is.
In an emergency I'm flipping off everything, load or not. It should work at least once, right?

Thanks for the great explanation..wish I had known this earlier… when buying my IMO device last year I couldn’t get a solid explaination on that from anyone…when I asked no one knew any real facts.
Most of our conversations could probably stop right here LOL
Sure.
Problem is people still need to know what the English means. And on my setup there’s too much sticker spam all over the place, so it’s really not clear what even someone who knows English should pay attention to.
Thank you. I am not the only one annoyed by those overly excessive red warning stickers.
These aren’t necessarily truly reliable at full rating. ACs and HPs very very rarely go to full amps.
Well, crap. There goes that idea. Just wire it direct and use this as safety disconnect and isolator combined!
