Power One Aurora UNO 2.0 and 2.5Power One Aurora UNO

The Power One aurora UNO-2.0-I and UNO-2.5-I are the latest single phase string inverters in the Aurora range. A new-look inverter but packed with Power-One’s proven high performing technology. The new look inverter has new features including a special built-in heat sink compartment and front panel display system.

The smallest of Power-One’s outdoor range, these new products are the right size for the average rooftop installation. This rugged outdoor inverter has been designed as a completely sealed unit to withstand the harshest environmental conditions.

The high speed MPPT offers real-time power tracking and improved energy harvesting.

Despite the isolated operation, the Power One Aurora UNO-2.0-I and UNO-2.5-I feature an efficiency of 96.3%. The wide input voltage range makes the inverter suitable to low power installations with reduced string size.

Features

  • Each inverter is set on specific grid codes which can be selected in the field
  • Single phase output
  • 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 prformance 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
