First off, I have not read through the thread, so this is probably worthless. Add to that, I’m speaking about my experience with a different model, a Growatt 3000TL LVM-48. I do however have the same model you’ve referenced as well (I’ve never used it, I just bought a bunch of leftover “junk” from Current Connected during their move, I assume it works).
Back to the 3000TL LVM (non ES). I purchased it from Watts247, it was my first all in one and first time straying from Victron, the price and size were too attractive to pass up for my tool trailer build.
I installed it without issue, used it for a couple months of very light, intermittent use. I never connected an AC input to it, as I have WAY more solar on the roof than my trailer can possibly use during a standard work day, which is basically a small fridge, and maybe 5 minutes of microwave use, one or two times a week.
Fast forward months later, plans changed for no reason other than me liking to tinker, and missing the monitoring abilities of Victron. The Growatt became a bench test unit.
I again bought something like (25) 200a 12v batteries from Current Connected for almost nothing. I wired them up in 4s groups to charge and discharge for a capacity test.
That’s where this ties into your story, when I connected the grid input, the ground screw was essentially stripped from the factory, as soon as it began grabbing the wire, nowhere near “tight” it stripped out immediately. This was being done by hand, not my first rodeo, it was annoying.
That said I reached out to Watts247 multiple times, emails, calls, the whole works. Never heard a single word back and after about two weeks I simply reached out to my bank and filed a dispute, I made it clear in the dispute I just wanted him to make any attempt to respond, never heard anything back, he didn’t respond to the dispute, I ended up with a refund.
So not I have an inverter I suppose works in off grid mode, I’ve tried connecting grid input with what I thought were clever ideas and I get similar errors to you.
Long story I know, but maybe check and make sure all your wires are indeed connected.
