HI All I”ve worked with many high voltage AC hydros and a few AC direct. Having a 2kw one is really small, and I can see why there were issues.
I recommend doing it this way,. 1. install a XW 600v controller. 2. take the output of the hydro after all safety/regulation controls and rectify it and feed it into the CC. 3. set the CC max charge rate to a bit below the output of the hydro. That way the hydro regulation will work normally. As the hydro output lowers due to lower water flows, you will have to adjust the CC output. With an AC direct hydro there is usually a failsafe device which interrupts the water flow ( flow diverter) if the HZ get too low, so you really don’t want that to happen. My concern with going through the inverter as the charger is much lower efficiency and its not as fine adjustment as the CC leading to lower outputs and more potential issues. 4. The xanbus /battery will comm with the CC for regulation, as it turns down the CC, the hydro regulation will reduce output with its dump loads, all normal. 5. and it leaves both inverters for normal use. jay peltz power > On Jun 29, 2021, at 5:40 PM, Jerry Shafer <[email protected]> wrote: > > I bet if you thought a little harder, you could get it even more complicated. > If the hydro has both freq and voltage control then look at a dumb charger. > Keeping it all independent will be safest.
