Happy Breffast!
I actually just posed this question to a retailed regarding a 12V model that's UL1741 certified. How can it be UL1741 certified, but not have a grid code in the software? I was considering upgrading my MultiPlus Compacts to the MP 12/3000 UL1741 models, but wanted to make sure it would ramp down power output in response to frequency. They told me Victron's national sales rep said there's no backfeeding possible in the USA (for now, I would hope).
So what's the point of the UL1741 cert?
You can use it in an NEC compliant installation, i.e., 1) completely off grid or as 2) grid backup or 3) off grid with grid backup.
