Controllers can follow several strategies to optimize power output. MPPTs may switch among multiple algorithms as conditions dictate. In this method the controller adjusts the voltage from the array by a small amount and measures power; if the power increases, further adjustments in that direction are tried until power no longer increases. This is called perturb and observe (P&O) and is most common, although this method can cause powe.

Solar electric inverters require the utility frequency to be at or near 60 Hz in order to operate. When these harmonics are present, they distort . . Thus, solar PV systems as well as other inverter coupled generators (e. Windturbines) and storage units must take over additional grid supporting tasks of conventional power plants in order to allow for secure and stable operation of electrical power systems at all times. This feature allows adjusting the duration of the alternating square pulses.
