Definitions
- a trigger signal is applied via line 222 that brings energy storage system 230 online to DC buss 120 (to provide temporary power until GENSET 112 is up and running) .
- the trigger signal also directs energy storage system 230 to provide startup power to GENSET 112, which is switched on by a trigger signal on line 224.
- Energy storage system 230 provides startup power to GENSET 112 until GENSET 112 is running independently on its external fuel supply (e.g., diesel fuel or gasoline) .
- transfer switch 106 transfers the input power from main power source 102 to GENSET 112 and energy storage system 230 ceases to provide power to DC buss 120.
