William, I always connect the hydro side of the diode to the diversion load with the contactor, so I don't pull the battery down while regulating. The diversion load must draw enough current to pull the hydro voltage below the absorb voltage. Use ohms law to calculate the resistance. David Katz

I appreciate any help on these questions: I need to rework a diversion control system. 1. I am going to use a mercury wetted relay driven by the Aux relay in an FX inverter set to actuate on high battery to connect the DC Bus to the diversion load. Sound OK? 2. Can I connect the hydro to the DC Bus (via a diode) using a breaker? I need OCP but I don't want anyone to disconnect the breaker and risk over speeding the water wheel. I could label the breaker "Do not open." I have been using a fuse, but if it opens, it is likely to remain undetected for a longer time. Thank in advance.
