What is TommaTech Uno Atom 0.6 kW Single-Phase Inverter?
TommaTech Uno Atom 0.6 kW Single-Phase Inverter is the 0.6 kVA member of the Uno Atom series, developed for smaller solar panel arrays. It connects to a single-phase grid, has a single MPPT input and a compact housing measuring 267 × 328 × 116 mm. This model is positioned as the entry step of the family.
At this power level the upper limit for the PV array is 900 Wp, which is about 1.5 times the nominal AC power and lets the inverter use its rated power for longer as irradiance changes through the day. The maximum input current is 14 A, and the highest AC current at the output is 2.81 A.
The low start-up voltage (50 V) and the MPPT lower limit, which goes down to 45 V, help production start even in the morning and evening hours when irradiance is weak.

Which projects is it suitable for?
The 0.6 kVA class; suitable for small roofs, terrace and garden arrays, tiny installations that cover a single critical load during the day, and those who want to start their first solar investment small.
Use in Antalya and Solar Nexo support
In Antalya the roof surface gets very hot in summer; the inverter's operating range of -25 to +60 °C and its natural cooling are an advantage in this climate, but it is still recommended to mount it on a wall that does not get direct sun. IP65 protection shields the housing against humidity and dust in the coastal region. Solar Nexo handles supply, project design, installation and commissioning. You can download the datasheet from the document section of the product page and compare the technical data against your project.
