Main features:

High efficiency 50kW~100kW inverter

Aurora® Grid-Connected Central Inverters offer a unique, ultra-efficient, easy-to-install design, long life and competitive initial acquisition cost combination, and significantly increase the return on investment of solar equipment.

Industry leading features and performance

High efficiency provides more energy - up to 95.8% (95% CEC)
Master/slave configuration (100kW model) minimizes module failure loss and reduces noise (ultra-low audible noise): switching frequency exceeds audible range (18kHz)

Unparalleled application flexibility

Full power wide MPPT working range at high temperature: 330~600VDC

Industry recognized reliability

The enclosure with IP20 protection level does not require any other cooling system, and the ambient airflow is sufficient and the network operation meets international standards.
5-year warranty, can be extended to 20 years

Easy to install design

Reverse polarity protection minimizes potential damage caused by wiring errors during installation. Panel mounted LCD displays provide real-time updates for all critical operating parameters
RS-485 communication interface Integrated DC switch for each 50kW module for easy replacement of AC and DC integrated protection (fuse and OVR)
Integrated AC magnetic circuit breaker anti-island protection

High efficiency over a wide range of operating conditions

At rated output voltages, the PVI-CENTRAL-100 inverter is capable of achieving efficiencies as high as 95.8% (CEC 95%). The image to the right shows the range of industry leading performance and continuous load conditions for all models at three discrete MPPT-voltage reference points.

Standards and specifications

Aurora® inverters meet the requirements for grid-connected operation, safety and electromagnetic compatibility standards, including UL1741 and CSA-C22.2 N.107.1-01.
