Ooh blast, didn't scoll down that far thought it ended at the links. Sorry for that.
Did you read the whole article? There's an update at the end that says they installed a micro-inverter system a year ago and it is working well. They had trouble installing it because of a bad wiring harness, but the technology works. If the author thinks today's micro-inverters are similar to what was available in 1980, he isn't very knowledgeable about the subject.

Nice article why NOT to use micro inverters.

Hi Group :)
Just an update on the 8 Metre Solar Catamaran Project.
Purchased so far:
2 Ray Electric 48v Outboards
48v Balqon 400ah 20kwh battery bank
48v CALB 72ah will become a 12v house bank and 24v trolling motor for tender and gps autopilot
12 SYFD-FSPC180W-1 System Voltage 24V Vmp(V) 32.92V Imp(A) 5.48A Voc(V) 39.80V Isc(A) 5.85(A) semi-flexible solar panels
2 Samlex/Cotek 48v 3000w inverters
2 Power Jack Smart Generators 48v
1 Alphagen 52.5v Generator
1 Incinolet Electric Head
1 700w Drought Master Atmospheric Water Maker
1 Craig Cat boat Tender
etc...
So I am getting near to the date to start installing all this. What leaves me in a conundrum right now is the selection and string sizing issues of the charge controller. I might add that I am leaning heavily toward a pwm charge controller 440amp or 155amp from coleman air. It has the necessary settings to adjust the charge rate for lithium batteries and when I'm ready I can hook up a wind turbine to it.
Any constructive thoughts on charge controllers would be appreciated especially how it relates to sizing strings in series and parallel.
