String inverters


These three-phase inverters for domestic installations, are available in three power ratings: 5.8, 7.5 and 8.5 kW. 

The topology of the TRIO-20.0/27.6 inverters has been redesigned to ensure that the TRIO-5.8/7.5/8.5 models also enjoy high conversion efficiency across a wide range of input voltages, and the double MPPT gives maximum installation flexibility for an optimal energy production (TRIO-7.5/8.5 models).

The all-in-one residential three-phase TRIO-5.8, 7.5 and 8.5 kW inverters deliver performance, ease of use and installation, monitoring and control. With their 98% peak efficiency and wide input voltage range, the residential TRIO inverter means flexible installations and powerful output.


Product Highlights
