Using the auxes as a PWM turbine controller ?

[Viking]

Hi there

I'm trying to figure out a neat way to use my classic 150 to control my turbine.
This is the situation.
I have 2160 watts solar working just great on my classic, it gives me 0.3 KWh on a bad winter day in Sweden.Therefore i would like to add a turbine to the system.
I have this turbine

I was thinking to connect the turbine directly to the battery, use aux 2 "opportunity hi" to dump energy (low 27 volts ,high 28.8 volts) and aux 1 (29 volts) to brake the turbine .
Its a 24 volt system in a cottage, turbine will be stopped when we are not there.
I know the classic isn't intended for this, but should be possible?

What are your thoughts?

Best Regards

I can't think of any reason why your suggestions would not work
The more elegant and expensive solution would be to use a Midnite 1.5Kw DC Clipper and have your solar Classic control it via Clipper control on AUX2 (or AUX1 if you used AUX2 for a WBjr) then the DC output from the Clipper connected to the battery bank.
The less expensive solution would be use AUX2 to switch in a dump load. For this I would just use FLOAT HIGH from AUX1 to enable an SSR to insert a resistor load between + and - from the turbine AND also include a power diode between the resistor + and the battery + (In the MNClipper circuit a 3phase bridge rectifier is used with the + to all three AC inputs and then output from DC+)
