Three-phase string inverters

This new generation three-phase inverter for domestic installations, is available in three power ratings: 5.8, 7.5 and 8.5 kW. The compact, transformerless TRIOs are the latest products in the family for their performance, ease of use and installation, monitoring and control.

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 new generation inverters can integrate power control, monitoring functionalities, and environmental sensor inputs, all without requiring external components. A compact expansion card gives access to the Ethernet datalogger, which allows parameters to be monitored both locally (with the integrated webserver) or remotely (via Aurora Vision), via a LAN connection.

Highlights

True three-phase bridge topology for DC/AC output converter

Transformerless topology

Two independent MPPT channels for TRIO-7.5/8.5 allows optimal energy harvesting from two sub-arrays oriented in different directions (one MPPT channel for TRIO-5.8)

Flat efficiency curves ensure high efficiency at all output levels ensuring consistent and stable performance across the entire input voltage and output power range

Wide input voltage range

Remote inverter upgrade

Reactive power management
