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
