 Product Description


ABB, Aurora UNO-7.6 1-Ph Grid Tied Inverter, 7600W, 208/240/277VAC, 60Hz, DC Discon, 2 Dual Unfused i/p, 2 MPPT, 10 Yr Warr, Ungrounded, RS485, Arc-Fault Protection, UNO-7.6-TL-OUTD-S-US-A

UNO-7.6 is a feature-rich transformerless inverter that is powerful and flexible enough to operate like two inverters. This means fewer inverters are needed to fit residential installations.

Available in 7.6kW (or 8.6kW, see UNO-8.6), the ABB UNO-7.6 inverter is well suited for North American residential rooftop installations and provides the system flexibility, levels of performance and reliability that designers need. The wide input voltage range makes the inverter suitable for installations utilizing a reduced string size.

ABB is the only manufacturer who can offer a fully-loaded, large-residential system using one inverter. ABB‘s high speed and precise Multiple Power Point Tracker (MPPT) algorithm enables real-time power tracking and improved energy harvesting. The dual MPPT input enables more orientations of PV strings to be connected at the same time; thereby, maximizing the energy harvesting and flexibility.

The UNO-7.6 inverter is extremely lightweight and simple to wall mount, while still featuring an integrated DC disconnect with combiner, lowering overall installation cost.


  • Highlights - Dual independent MPPT channel compatible with a 40Amp residential panel sized breaker. Outdoor NEMA 4X rated enclosure for unrestricted use under any environmental conditions. Wide input range for increased stringing flexibility. Minimizes installation space with side-by-side installation. 96.5% CEC efficiency.
