Not sure if this has already being posted but looks like Enphase has begun rolling out the IQ8 inverters

I've been searching around and haven't been able to find any line diagrams of how the IQ 8 can be hooked up. What I'm trying to understand is how they create a micro grid AND anti-island from the main grid during grid down situation?

They use a smart transfer switch that aggregate solar, battery, generator, loads/load-control, grid into one device. With the use of current transformers, very fast switching and power flow control they can always keep power on.
 
Well Merry Christmas! Thanks!

I wonder why they have the 208 variant?

IQ8H-240-72-2-US
IQ8H-208-72-2-US

The footnote says: (1) The IQ8H-208 variant will be operating in grid-tied mode only at 208V AC.

Some properties/electric service is only 120/208V. I thought it was interesting they aren’t making an IQX variant (96 cell)
 
So you need the IQ system controller with a Combiner 4 (looks like envoy will be powered from the system controller). Can’t wait for a system review to see what it can power.

4IQ 10T batteries in parallel is 40kWh and 15.36kW continuous and 23kW peak output. What would you like to power?
