Re: [Electric Boats] Solar Catamaran Project

Did YOU read all of the update?

"However, do not misconstrue our willingness to beta-test SMA's new microinverter to mean I take back everything I said in my prior post. In fact, I stand by everything I have said (despite the hateful comments some readers have sent my way). "

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.
