What is the TommaTech Trio Atom K 3 kW Three-Phase Inverter?
TommaTech Trio Atom K 3 kW Three-Phase Inverter is the 3 kW model of the Trio Atom K series, developed for homes and small businesses with a three-phase connection. It operates in sync with the grid, feeding the energy produced by the rooftop panels directly to the site's consumption and the surplus to the grid; two MPPT inputs provide flexibility in mixed roof layouts.

Since the maximum PV array power is 6,000 Wp, the design allows a DC/AC ratio of up to 2.0; the actual ratio is determined by the project. On the communication side there are RS485, DRM and USB for software updates; remote monitoring and smart meter connection can be added optionally via a Wi-Fi or LAN dongle.
Which projects is it suitable for?
This power level is a suitable scale for single-storey detached homes, rural country houses and small workshops. Three-phase subscribers who want to partly cover air-conditioning and water pump loads in summer with their own generation are the main target group.
Use in Antalya and Solar Nexo support
The Mediterranean climate is advantageous in terms of sunshine duration; according to PVGIS data, 1 kWp of capacity in Antalya theoretically produces about 1,656 kWh per year. Salt and humidity should be considered on the coast, and dust and temperature fluctuations inland. According to the datasheet, the unit can operate between -30 and +60 °C (efficiency is derated above 45 °C).
Solar Nexo manages the process from site survey to commissioning: roof and grid study, panel-inverter matching, installation, monitoring connection and technical support afterwards.
