I am definitely going to need to check that out in person before I do the solar on my house... That is some years off still though
Any time! I'll update here once I'm actually finished and the whole thing is legal (ish)
edit on this last one: seller is trying to be scammy, wants me to talk to the manufacturer. no dice, law says they have to take care of the product they sold me - fair enough, you get a nice letter in legal gibberish then. ugh.
UPDATE ON THIS SHIT
after i exchanged 5 emails with "customer happiness" of that seller wihtout getting anywhere, i dropped a bunch of 1star reviews on trustpilot and suchlike and suddenly got a response. actually TWO responses.
first: from the manufacturer. seems the seller did actually contact them on my behalf.
second: from the seller, with an RMA ticket and shipping label, telling me to send back the unit then.
... either one would've been fine by me, honestly, but - it's good that they actually went with both! becauuuuuse... after asking a random install related question, the manufacturer just said "yup, that thing is most certainly broken, please send it back via your seller to have it replaced"

yeah... fuckers.
now here's the fun part: the "old" unit that I have isn't made or sold anymore, so they will have to replace it with the new version. which is 200€ more expensive. hence, I fully expect the scammy shit shop to figure that out, keep the replacement unit they get and tell me "sorry, not made anymore, can't replace, here's your money back" and pocket the change.
also I fully expect the whole shit to take weeks, so I have actually ordered the follow-up model myself from a different shop (ofc). so if I do end up being surprised and sent the new version as a replacement after all, I'll be able to send that back and not lose any money either, so win win either way I guess? except for the two weeks of my life i lost by getting annoyed and worked up about those assholes. ugh.
