That was a cool tear down. A video on how these work would actually be really cool. Ex: how do they sync with the grid, and how do they detect if it goes down. Especially when there are many of these on the grid, how does one inverter not think another inverter is "the grid" and keep going, for example. I presume it goes by current draw, if grid goes down it will try to pull massive current?
The simplest passive anti-islanding method is just measuring the voltage and frequency of the mains and shutting down if its out of spec (1.1% for voltage, ~2% or less for frequency).

Nope.
Voltage actually varies quite a lot because of the impedance/resistance of the network and cables.
Dave, I love the solar content. I find the micro inverters very interesting. I was wondering if you think you would ever be able to get your hands on a US version of one? I'm curious how they handle creating and managing the split phase power we use in the US. I see that enphase does make a US split phase inverter

Didn't know a 120V split phase inverter was a thing, thought they were all 240V?
Yeah looks like the actual spec is +10/-6%, and preferred +6/-2%. Not sure where I got 1.1.
Hi,
I hope it is ok to ask here - can anyone please tell me which wire diameter would be safe to use from the Hoymiles 800 to the outlet? I have read about it, but it would be nice to hear from someone who is using this or similar inverter for a while.
Thanks
Didn't get the manual. But the confusion always comes from the fact that in the original package the manufacturer included no-name no-label stranded cable that seems even thinner than 14AWG
I thought of using 12, just wanted to confirm since that is one of the rare electric things I've never worked with (solar systems).
Thanks
