As every field of life becomes more dependent on electric power to operate and grow, backup power systems, like generators, are playing a progressively vital role in guaranteeing uninterrupted supply of power. Generator selection greatly depends on the amount of backup power needed for a specific application. An application may need minimal supply of backup power to ensure uninterrupted functioning or it may need full power of the backup system. It is hard to find a generator that matches the application requirement exactly. This is one area where parallel generators can shine.
