The UNO 7.6 and 8.6 kW transformerless inverters are dual MPPT inverters that maximize energy production for residential rooftop applications facing multiple roof angles/orientations and varying string lengths. It is the installer’s choice for ease and flexibility of installation, optimizing energy production and meeting upcoming grid interactive requirements.

These innovative inverters have incorporated Arc Fault Circuit Interruption as required per NEC 2011 and meets upcoming requirements for NEC 2014. Individual MPPT channels support up to 71% of the inverter's full power rating thus offering the highest design flexibility on the market today. These inverters are extremely lightweight and simple to wall mount, while still featuring an integrated DC disconnect with combiner, lowering overall installation cost.
