The AURORA maximum power point tracking (MPPT) algorithm ensures that the inverter operates at the absolute maximum power point of the array. The ULTRA inverter further improves the MWH plant output due to a maximum inverter efficiency of 98.6%. In addition, the ULTRA's wide input voltage range provides maximum energy harvesting over a wide module temperature and insolation levels.
The ULTRA 700/1100/1500 inverters host some of the most sophisticated communication and grid management capabilities for utility monitoring and interconnection requirements. These features can be configured based on specific customer requirements. The ULTRA inverter series is a true utility scale product in every sense. The inverter monitoring further incorporates a Power-One intelligent string combiner option to provide array level monitoring.
