What is TommaTech Uno Home 3.0 kW Single-Phase Inverter?
TommaTech Uno Home 3.0 kW Single-Phase Inverter is the 3 kVA single-phase model of the Uno Home family. With two MPPT inputs, a wide operating range between 70 and 580 V and a fan-free construction, it is made for residential roofs; it is positioned as the entry step of the family.
For 3000 VA nominal output, up to 4500 Wp of array power can be connected on the panel side; this is about 1.5 times the AC power. The maximum input current of the MPPT inputs is 12/12A; the start-up voltage is 100 V and the highest AC current is 14.3A.

Use in Antalya and Solar Nexo support
In villas and detached homes in Antalya, the air-conditioning load overlaps with production hours throughout the summer; two MPPTs make it easier to get the most from the sun on two roof surfaces, such as east and west. Natural cooling and protection suited to outdoor conditions are an advantage against coastal humidity and dust. 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.
