PVi-cenTRal-50 PVi-cenTRal-100 GENERAL SPECIFICATIONS CENTRALIZED MODELS
These Aurora commercial-grade inverters are designed for large solar applications such as apartment buildings and industrial facilities. These extremely scalable modular inverter systems, based on 50kW conversion modules, increase usable power and improve availability. The reduction of performance in any individual inverter will not impact the energyharvesting capabilities of other modules. Industry-leading power conversion efficiencies of up to 95.8%, combined with high-speed Maximum Power Point Tracking (MPPT) channels, optimize energy harvesting across a wide array of operating conditions. Inverter systems are delivered pre-configured and pre-tested, significantly reducing on-site wiring and testing.
Features • Reduced susceptibility to a single fault. In case of a component failure, a maximum of 50kW will be lost • Reduced acoustic noise due to the high switching frequency • Reverse-polarity protection minimizes potential damage caused by array mis-wiring • Maximum input voltage up to 600Vdc, high design flexibility and reduced DC distribution losses for large scale PV plants • Integrated DC and AC distribution and protection. Fully equipped for connection, additional accessories not required • Easy installation and maintenance procedure. Front extractable DC/AC converters and accessibility to all critical parts • High efficiencies deliver more energy • Two independent RS-485 communication interfaces - for inverter and intelligent string combiner monitoring • Integrated DC disconnect switch for each 50 kW module AC and DC side integrated protection (fuses and OVR) easily •
replaceable Integrated fuse grounding kit with ground-fault detection and interruption (GFDI) compliant to UL1741
