Interesting.
How my Turbine works is, my Turbine controller allows complete control of the turbine, see below. Do you have some level of software control like this? (or able to manually set?).
The output (48v in my case) feeds into a Smartshunt (as below) and what happens as the power from the turbine increases my MPPT’s sees this and ramp down accordingly.
This is what you want to do? but the diagram above does not look correct to me (but i could be wrong), i would expect the feed from the rectifier to go (just) into MWS 24V Relay and the two outputs from that, one to the dumpload and the other to the batteries, otherwise your batteries would get overcharged.
Something like this…
Remember the Turbine controller should only switch to dumpload when the turbine reaches the stall level (in my case a voltage level, that way my batteries will never get overcharged by the Turbine) and only turn back on when the Reset level is reached, so if yours does this you should be ok, this exactly how mine works using Victron’s MPPT’s.
