I wonder if there is any system loss, possible clogging, turbulance due to how your water splits to the two generators.

The penstock should remain full, turbulence should be nonexistent.
Only clean water with no fish, entering the penstock, so clogging is a nonissue.
The size of turbine nozzles compared to the dia of the penstock assures a full supply of water pressure at all times.

I know it’s on a different scale but we have a split penstock design too. It only makes sense as we can shut one intake down or the other and still flow to either turbine.

I think there are some losses doing that so it is rare, but we can do it.

We are run of river anyway so we can only swallow what Mother Nature gives us, minus 6 percent for fish passage

So I haven’t posted my progress in a while so I thought I’d update you guys.
So, I FINALLY got the leaks fixed which was difficult and to be honest a bit expensive . But I finally got the hydro online last week. I still have some issues with turbulent water entering the penstock at the Coanda box. I was losing all kinds of power from it during the night. But after building a baffle out of a piece of 8” pvc pipe to calm the water after it enters the Coanda box it seems to be working much better. I can make around 1.8 kw continuous depending on the flow of the creek. I couldn’t be happier with that. I combine that constant power with my 5kw solar array and my batteries are usually well charged.

As of right now I don’t have a few of my bigger loads on the critical load panel ( alt energy panel ) the hot water heater and the wife’s hot tub are two big ones. I am planning on buying another Schneider inverter and solar charger to add those loads and be completely grid free.
If anyone has any questions or advice please chime in.
