We have been having a lot of wind the past two days; my engineer was over last evening. We were doing the test you ask for and at one time we disconnected the batteries from the turbine. That apparently set in motion a series of self-test and we got over load, excessive charging and dump. Through out the evening we noticed that the controller functioned very well switching between charging and dumping. So we were very satisfied with the controller and turbine.
