Lots of misinformation in this thread, so I’ll try to help future noobs. I was here a few months ago asking similar questions, it’s time to give back.
1) what is overpanelling? When you have more total solar panel watts than what the charge controller can accept (700w). 701w wont blow it up. That guy was joking and is a salty hand around here. If you want to know how this black magic works, research MPPT charge controller.
2) is it safe to over panel? Yes, as long as the Voc limit (150volts) is not crossed. 151v will blow it up, but bluetti has put a “software” safety switch that seems to have worked for some of you. I dont know how it works with certainty, but I suspect it uses mosfets, so i wouldnt challenge it all the time, as the safety measure might fail.
Caveat: Dont rely on the voc written on the panel. That Voc is only at temp of 25C and goes up as it gets colder. Research this forum and do the math -or if you want to play it safe don't exceed 120v nominal (80%)
