Here is the solution:
Get 2 x Schneider LC1D258 contactors with the appropriate coil voltage you are using. Then, bridge 3 of the 4 n/c contacts. On the opposite side of that bridge, add the turbine 3 phase wires . Then, tap the turbine 3 wires to 3 of the 4 n/o contacts next to the turbine wired side of the contactors. Then, connect the controller's 3 input wires (that would've came from the turbine before the contactorswere introduced) to the 3 of the 4 n/o contacts still available, on the side where the bridge is.
Now, connect your turbine controller directly to the lifepo4 bank. Then use the bms's normal output (which is protected by the bms), and power the 2 contactors on.
There you go.
Thus, if the bms is all good and no faults, the contactors stay on, turning the n/o contacts closed, and turning the n/c contacts open. Your turbine controller is charging the battery. If the bms opens its circuit, the load will switch off, thus the contactors will loose power. Thus the original n/c contacts which were open during power, will close due to contactors loosing coil power, and that will short the turbine. Your turbine controller is still connected to the battery, but cannot charge.
you can also apply the principle with solar. But not with those specific contactors, instead, just a basic 3phase contactor with 3 n/o. Using 2 of the 3 contacts, you can cut + and - pv input, without damaging your controller, because its still on, but cannot charge, of cause. The bonus is that you also have unused contacts as backup, when using the LC1D258 and normal say LC1D32 contactors respectively.
I hope this helps. I did not make a drawing, but will if need be.
