What is TommaTech Uno Atom N 2.7 kW Single-Phase Inverter?
With its 2.7 kW output, TommaTech Uno Atom N 2.7 kW Single-Phase Inverter is one of the models that complete the Uno Atom N series; it is a single-MPPT solution designed for small-scale solar applications. The series stands out with an efficiency of up to 97.5%, and this model can be regarded as one of the mid-power steps of the family.
Zero Export mode ensures that the energy produced by the inverter is used only for on-site consumption and is not fed into the grid. This makes it easier to comply with grid regulations in projects that have export restrictions or aim only at self-consumption. The low start-up voltage of only 80 V helps production begin earlier in the morning and evening hours, when irradiance is low.

The single-MPPT design is sufficient and economical for a panel array that faces one direction and is not shaded. In array design, the compatibility of panel voltages with the MPPT range should be checked in the datasheet.
Which projects is it suitable for?
The 2.7 kW class; suitable for apartment roofs and small houses matching the consumption of a household of 2-3 people. In self-consumption-focused installations, the zero-export feature makes it easier to manage grid-side restrictions.
Use in Antalya and Solar Nexo support
In sunny Antalya, a low start-up voltage helps production begin in the early hours. A site survey is recommended to check shading, cable cross-section and ventilation. The Solar Nexo team prepares your project and carries out installation and commissioning. The datasheet can be downloaded from the document section on the page; our engineering team can help with technical details.
