If your controller controls load after the inverter that is ok.

You can cover the case of inverter failure with a back up C60 controller to protect the battery if the inverter fails. Normally the C60 will not dump and it must have its own dump load. There is no way that the C60 can be used to feed the inverter but I think you understand that.

Many have proposed using an inverter after a C60 in place of the dump resistor and that is a definite no go area.

If you want heat alone then this is not a clever scheme as heating controllers work best with turbine volts proportional to wind speed, but it is not much worse than a fixed voltage link at higher volts.

I know absolutely nothing about your turbine, but direct connection to heaters with suitable control may not be out of the question as it would most likely be working well over 24v at times when you are producing significant power. Cut in at 24v would likely give you 70 -80v at full load and line losses may not be that bad.
