Understanding what the two power settings mean.

Taking a look at the two settings under “General”  it can be very confusing seeing the two setting options:

  • “Floating Voltage Point” This is the voltage coming from the wind turbine via the controller to the battery system. and at which point you want it to stop and or dump to the dump load.
  • “Release current” is NOT the current setting to release the brake as it would suggest, it is the level at which the controller will dump power it senses on the battery side of the controller.   In a scenario whereby you have a separate Solar system running your battery bank and you have supplemented the system with a wind turbine,  So often you’ll walk past the controller and hear the fans going ( depending on the model) your dump load resistors might be internal or external to the controller casing.  When I first started using this product range I noticed that it seemed to be activating even on a wind still day. This is normally due to the “Release current Amp” setting being set too low and the controller is seeing the power coming into the battery system from the Solar system.
    If you have this setting set below the number of AMPS coming from your Solar System to the battery bank i.e. 35A on the wind controller and your solar system is pushing 40A, the wind controller will try shaving off the extra 5A to the Dump load resistors, which in turn cause the Solar inverter to try ramp up power if available to the battery bank, and the two devices will end up working that much harder, so be sure to set this setting to match what your inverter is set to change at and it will resolve this issue completely.
    WARNING be sure not to set this too high and damage your battery.
