Applying diversion loads on the input or applying mechanical braking during voltage regulation instead of using the
TriStar diversion at the battery is possible. However, these other methods can be problematic since it is difficult to
match the gradual reduction in power required to regulate battery voltage. Keeping the turbine load for optimal
rotational speed (with a clipper circuit or mechanical braking) while maintaining a steady power level for the TriStar
MPPT during Absorption charging and Float phases is difficult to co-ordinate with rapid changes in power levels.
In addition to being able to keep the turbine under load during absorption charging an independent braking system
will need to be able to shut down or keep the turbine loaded with a manageable rotational speed in case the TriStar
MPPT controller shuts off. If the turbine has no furling or mechanical braking it will need some type of clipper circuit.
This braking mechanism might be the same device that is used for overvoltage protection.
Turbine and System Requirements: Design Considerations
Operating Voltage vs. Power Window
What is the operating input voltage window for the TriStar MPPT (150V & 600V) controllers? In Wind mode, these
controllers are designed to be able to start operating whenever the input voltage is greater than the battery voltage
and the absolute maximum operating voltage is 145V for the TriStar MPPT (150V) controller and 525V for the TriStar
MPPT 600V controller. In addition, the TriStar MPPT 600V controller’s maximum operating input current (Iin) can be
as low as ~8 Amps for Vin < 100V and less than 15 Amps for Vin > 100V. At higher input voltages the TriStar MPPT
controllers will derate to the maximum operating output current. It is important to consider that the maximum
charging current will start to derate as the input voltage increases closer to the maximum operating input voltage.
