What is TommaTech Uno Home N 4 kW Single-Phase Inverter?
TommaTech Uno Home N 4 kW Single-Phase Inverter (4.0 kW) is one of the mid-power steps in the Uno Home N family. The family has an efficient two-MPPT design made for residential solar applications and aims to generate power reliably under varying irradiance conditions; its peak efficiency is 97.5%.
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.

Two separate MPPT trackers allow two roof surfaces facing different directions or at different tilts to be optimized independently; on an east-west roof, for example, each array operates at its own operating point.
Which projects is it suitable for?
The 4.0 kW class; suitable for medium-sized detached houses and duplex homes. 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.
