Following Zigmundo's Wind generator post, what reulators do you have?
I have a small Rutland 503 for trickling my Start battery, but I have just bought a 27w panel for trickling the Domestics.
As this is only the starter for 10 system, and I will be upgrading as time goes on, what regulator gives decent overcharge protection, and displays outputs (perhaps an RS232 interface?).

I already have Voltage Sensitive relays and a DCM600 monitor and Merlin AMS alternator regulator.
