4.0 OPERATION
The array V
mp
is the voltage where the product of current
and voltage (Amps x Volts) is greatest, which falls on the
“knee” of the solar module I-V curve as shown in Figure 8.
Because Traditional controllers do no operate at the V
mp
of the solar array, energy is wasted that could otherwise be
used to charge the battery and power system loads. The
greater the difference between battery voltage and the Vmp
of the module, the more energy is wasted.
TrakStar MPPT technology will always operate at the
V
mp
resulting in less wasted energy compared to traditional
controllers.
