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.
