No  its an old analog .. I just use it to run the solar and plugged in
the hydro just to read the AMPs.

Well the way it is now is:

solar pannels -> analog controller -> batteries
Hydro -->direct to batteries
batteries -->MPPT(?) (xantrex c35) diversion mode -> dump load

The solar side has a blocking diode, while the hydro just runs into the
batteries with no conroller.

Its tempting to run the hdyro through the analog but I don't trust myself
enough to do it.  I mean the solar side works good now and I don't want
to screw it up, and the direct to batteries setup charges them for sure.

I've been on the look out for another xantrex c?? series controller to
run the hydro through -- for one thing i've got the remote panel setup in
my house, so it would be nice to be able to monitor how things are going
from inside.

Then i want a 12 volt valve I can throw a switch from inside my house to
start the thing.. rather than put on the rain gear and go out there in
the cold rain while its nice and warm inside.

thanks again

   Hmm, this is an interesting design problem.  You will want that valve to be a
straight-thru design like a big plastic ball valve or perhaps a gate valve.  My
first thought for a potentially cheap solution is to mate a ball valve to an
actuator for an air damper, but I don't know if that would give the full
90-degree swing that you are going to need.

   Are there any suitable non-expensive electrical gate valves available in the
irrigation world?  The 24-volt irrigation valves that I am familiar with are not
straight through.

How about an auto power window motor mated to a regular gate valve? You
could add limit switches, or just use a cheap auto amp meter to see when
it reached a stop.

Second thought - You could use one of the motorized RV black water dump
valves, they are large bore, straight through blade valves designed to
handle some amount of "debris" in the water.

It should be safe to run the hydro through the charge controller as long as
you don't exceed the maximum allowed input voltage and use a big capacitor
to smooth out the AC ripple.  Since it's already 3-phase you are ahead of
the game since the output doesn't ever drop to zero volts.
