Don't know about the Rutland
But I had\have the 913 on my 43fter for yrs.
Linked to solar and my battery's by a "Trace" mechanical regulator
Had "pots" for all it's adjustments
Plus two "Dumps" to save using a brake when system full.
There was also a bypass sw in there. so It could send extra\excess power to water
It was supplied. and set up by Marine
Leccy at boatyard down in Adelaide. "Searles"
He did mainly fishing
boat installs and larger cruising boats.
So was well versed with what and how.
Buyer didn't want to pay price
So I still have Rutland. Trace. and dumps in shed.
Ready for next boat. One day. Radar
etc. I sold.
PS. Go down to a Marina in 30knots sometime. and watch all the Genny's working. Or braked.
The Rutland. In 30 knots put out a slight "hummmm"
Mounted on a s\s post bolted to stern cabin
roof, and clamped to stern rail. On a steel
They are the only ones you'll sleep under.
Not the most powerful. But give out regular amp's to a much lower wind strength than others..
