/ Boasting power categories ranging from 3.8 kW to 8.2 kW, the transformerless Fronius Primo is the ideal compact
single-phase inverter for residential applications. The high system voltage, wide input voltage range and unrestricted
use indoors and outdoors ensure maximum flexibility in system design. The modern design is equipped with the
SnapINverter mounting system, allowing for lightweight, secure and convenient installation and repair.
/ Several industry-leading features come standard with the Fronius Primo including a Wi-Fi* and SunSpec Modbus
interface for seamless monitoring and datalogging, Arc Fault Circuit Interruption (AFCI), and Fronius’s superb online
and mobile platform Fronius Solar.web. This makes the Fronius Primo one of the most communicative, efficient and
streamlined inverters on the market.
