Just finished checking out using Solar and Wind GTI together on my wind turbines. It kinda works. While the wind GTI controls the voltage and the solar follows. It does not always share the load. Sometimes it drops out and shares non of the load. But when it does share my voltages climb a little higher and hold. Then come back down slower than before. So they are not a good match but it does work some of the time. Have the equipment I just have to try guys.
