PVI-3.8-I-OUTD-US PVI-4.6-I-OUTD-US GENERAL SPECIFICATIONS OUTDOOR MODELS
This isolated inverter is optimized for use in residential applications requiring PV array grounding, such as some thin-film modules. This inverter has also been designed to serve all countries and regions with specific field-configurable set-ups available for all major country grid codes and display languages. The 3.8 and 4.6kW isolated inverters have all the usual Aurora benefits including dual input section to process two strings with independent MPPT, high speed and precise MPPT algorithm for real-time power tracking and energy harvesting, as well as regular high performance efficiencies of up to 96.9%. The wide input voltage range makes the inverter suitable to low power installations with reduced string size. Its high frequency isolated topology allows this unit to be light weight and compact in size to help with transportation and installation. This rugged outdoor inverter has been designed as a completely sealed unit to withstand the harshest environmental conditions.
Features • Each inverter is set on specific grid codes which can be selected in the field • Single phase output • Night Wake up button to access energy harvesting data and error log • Dual input sections with independent MPP tracking, allows optimal energy harvesting from two sub-arrays oriented in different directions • Wide input range • High speed and precise MPPT algorithm for real time power tracking and improved energy harvesting • Flat efficiency curves ensure high efficiency at all output levels ensuring consistent and stable performance across the entire input voltage and output power range • Outdoor enclosure for unrestricted use under any environmental conditions • RS-485 communication interface (for connection to laptop or datalogger) • Compatible with PVI-RADIOMODULE for wireless communication with Aurora PVI-DESKTOP AURORA UNO
