Not surprising. DC-AC Inverters and solar panels have become so cheap nowadays that microinverters are too expensive.
Yeah. Regardless of how much I have voiced my preference for string inverters, due to them being good enogh, cheaper, (and possibly maybe perhaps more reliable) - this is also the realistic default choice on most parts of the planet outside the USA -, I would really love to see microinverters succeed because there are many (even if small) theoretical advantages that can be had if only practical problems (mostly small, too) are solved. If I were to dictate the direction for the technology, it would be integration of the microinverter into the panel, and then standardizing on a super reliable yet cheap to manufacture AC mains wiring plug, so that no electrician would be needed for the connections, and wiring harnesses (with factory-made T joints and stuff like that) for 90-95% most typical installation layouts could be made in advance. Economics of scale and ease of installation would then bring the price down.
Right now, it's the opposite: thanks to standardization of MC4 connector (despite some compatibility problems, which people conveniently ignore, so let's ignore it here, too), DC strings are easy to do, and the electrician only has to wire up the inverter. With microinverters, you have to mount them, wire the DC side up, and
then wire the AC side, for which you need an electrician on the roof, and you likely have to wire up some distribution boxes on the roof as well.
But Enphase having to cut doesn't necessarily relate to microinverters having problems against string inverters. It could well be a market response for panel prices increasing in 2020-2021, and early adopters who got their systems installed "no matter how much is costs" already satisfied. Now market has responded by panel prices going down again but people are still not buying more PV systems currently.
