I don´t have any experince of that controller, my first impression is not to good, 5 sec conection time seems like forever to me...and everything i´we read about dump controller say relay is big no no, it´s not if, it´s when they fail and in my world a solenoid is just a big relay. I don´t like that the turbine is conected in the dump controller, it shoud be conected to the battery. if you are on 12/24 volt, put 10 bux (ish) on a ghurd controller. just my opinion tougth.
