2.2 Maximum Power Point Tracking
The output power of PV array was affected by sun irradiation level and environment
temperature. The max power point varies a lot under different weather condition.
Fig 2-2 : I-V curve of various irradiation under same temp. Fig 2-3 :P-V curve of various irradiation under same temp.
Max Power Point Tracking allows the maximum harvest of energy from PV array and delivered
it into battery. The MPPT software will continuously adjusts the operating points in an attempt
to find the maximum power point of the array no matter how the weather changes. With MPPT,
we can maximize the usage of the PV array, increasing the system efficiency by maximum 30%.
