Power-One's Aurora grid-tie inverters feature high energy yield and performance efficiencies of up to 96.3%. Power One Aurora inverters have a field-adjustable "start voltage" point that allows low end PV operating voltage down to 90 VDC. While there is some loss of efficiency at lower voltage settings, the inverter can operate with as few as 5 standard 60-cell modules in series.
The PowerOne PV inverter UNO series are single phase string inverters within the Aurora range. The smallest of outdoor inverters, has the right size for an small PV installation. This rugged outdoor inverter has been designed as a completely sealed unit to withstand the harshest environmental conditions.
