ABB’s UNO family of single-phase string inverters complements the typical number of rooftop solar panels, allowing home owners to get the most efficient energy harvesting for the size of the property.
The dual input section processes two strings with independent Maximum Power Point Tracking (MPPT). This is particularly useful for rooftop installations with two different orientations (e.g. East and West). The high speed MPPT offers realtime power tracking and improved energy harvesting.
Efficiency of up to 96.8% The transformerless (TL) operation gives the highest efficiency of up to 96.8%. The wide input voltage range makes the inverter suitable for low power installations with reduced string size.
This rugged outdoor inverter has been designed as a completely sealed unit to withstand the harshest environmental conditions.
Our most common residential inverter is the ideal size for an average-sized family home.
