Prime Power Systems automatically operate on-site generators to serve a facility's entire load. They step in as the primary source of power to a facility when grid power sin't available.
Its generator paralleling controls provide active synchronization and soft loading control of engine generators based on the facility's load demand. If the load increases to a predetermined level, the Prime Power System starts additional generators, synchronizes them to the generator bus and shares the load with the running generators. When the load decreases, extra generators are shut down and returned to automatic standby.
