Abstract
A photovoltaic system includes voltage limiting devices that are connected in series. A voltage limiting device clips a corresponding photovoltaic string to limit a voltage of the photovoltaic string. Unclipping of clipped photovoltaic strings is coordinated by a central controller or in a distributed fashion by the voltage limiting devices based on monitored string conditions.
