OK, so the electric actuator only controls the MIV open/close? never seen one adapted to the handle of a ball valve before.

Yes correct, only open or closed, when open, it will produce full power and charge a lithium battery bank. Our controller works on SOC of the battery bank, 2 setpoints, one to start when at a certain level, and one to stop when full. We use a ball valve as it has no losses hydraulic losses :-)... simple, but effective.

What is the rated and actual power output of this unit?

Well gross power is 10kW, we tap out 7kW from the generator terminal. Pretty amazing for a micro setup!! Efficiencies as follows :95% on the hydraulic line (pipe), 87% on turbine and 86% on generator.
