Used in combination with a Grid Energy Storage System Peak Lopping Inverter (PLI), power demands which exceed the available solar power, can be met from an energy storage system to support the grid in riding-through a potential voltage sag, thus stiffening the network and maintaining the solar array’s connected to the grid and instantly available once the peak has passed. This (optional) technology also allows the solar farm to operate seamlessly during short cloud-cover conditions, avoiding the crash starting of stand-by generators for transient “PV dips”.
