Power One Aurora UNO 2.0 and 2.5
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
