The ABB UNO single-phase/split phase residential inverter is a feature-rich transformerless inverter that is powerful and flexible enough to operate like two inverters. This means that fewer inverters are needed for residential installations and leds to a profound reduction in installation costs. It is well suited for North American residential rooftop projects and provides system flexibility, high levels of performance, and unmatched reliability.
ABB UNO’s wide input voltage range makes the inverter suitable for installations utilizing a reduced string size and classifies it has a high power, fully-loaded large inverter. Its dual Multiple Power Point Tracker (MPPT) input enables more orientations of PV strings to be connected at the same time; thereby, maximizing the energy harvesting and flexibility.
These inverters are extremely lightweight and simple to wall mount, while still featuring an integrated DC disconnect with combiner, lowering overall installation cost. They also incorporate an integrated wiring box, a natural convection cooling system, and the ABB standard 10 year Warranty, with available extensions of 15 and 20 years.
