I'm planning to install 50 solar panels on my roof, with one side having 3 rows of 10 panels and the other side 2 rows of 10 panels. I'm considering using the HMS2000-4t microinverter and connecting 4 panels to each unit. The panels are 405W with a Voc of 37.15V and a Vmp of 31.18V. Can anyone share if this setup works? Also, what wire size should I use?

Yes, you can totally set that up! Generally, you'll want to stick with 10 gauge wire, which can handle a maximum of 30 amps per line. So, you could run three of those microinverter units together on each line, giving you a total of five lines. Just make sure to check with your inspector to ensure everything's compliant. It's pretty flexible on how you configure it anyway.
One thing to keep in mind about the Hoymiles microinverters, like the HMS2000-4t, is that they don't provide real-time solar data. They usually take snapshots every 15 minutes. But I heard they've updated it to every 5 minutes, so it's a bit better now. Just remember, this is pretty common among microinverters.
