    A generator current control ensures that the generator always remains at the optimum operating point. The generator management allows the use of generators that have a low output power in proportion to the nominal load (see technical document "Sunny Island Generator - Whitepaper" at www.SMA-Solar.com) Load Control The load control enables control of the AC sources in stand-alone grids, control of a generator, and the specific disconnection of loads.
