How does an inverter and MPPT of a PV system Work? - Sustainable Energy - TU Delft - Duration.
Tracking the Maximum Power Point (MPP) of the photovoltaic array is very difficult due to the non linearity of its I-V characteristic which is dependent to.
The function of a MPPT is analogous to the transmission in a car. When the transmission is in the wrong gear, the wheels do not receive maximum power.

The value of V ref may be also chosen to give optimal performance relative to other factors as well as the MPP, but the central idea in this technique is that V ref is determined as a ratio to V OC. More Articles on Solar Technology. This is a dynamic quantity which changes depending on the level of illumination, as well as other factors such as temperature and the age of the cell. MPPT charge controls are now manufactured by several companies, such as Outback Power, Xantrex XW-SCC, Blue Sky Energy, Apollo Solar, Midnite Solar, Morningstar and a few others. As inverter power classes increase in power, the size of your test array becomes unmanageable. In most DC to DC converters, this is strictly an electronic process - no real smarts are involved except for some regulation of the output voltage. From Wikipedia, the free encyclopedia.

Although solar power is mainly covered, the principle applies generally to sources with variable power: for example, optical power transmission and thermophotovoltaics. Fill factor is defined as the ratio of the maximum power from the solar cell to the product of Open Circuit Voltage V oc and Short-Circuit Current I sc. MAXIMUM POWER POINT TRACKING (MPPT)
