Description

This is the popular Fronius Primo 15.0. A 15kW transformerless Fronius single-phase inverter for residential and small-scale commercial applications. Industry-leading features now come standard with the Fronius Primo, including: dual maximum power point tracking, arc fault protection, integrated wireless monitoring and SunSpec Modbus interfaces for seamless monitoring and datalogging via Fronius’ online and mobile platform.

The Fronius Primo can operate efficiently at a maximum input voltage of 1000 V, with a wide MPPT range of 270VDC to 800VDC.

This ‘Advanced’ model offers both Data Manager communication package and AFCI (Arc Fault) protection. The Data Manager allows WLAN connectivity, energy management, several interfaces and much more. Fronius Primo is a communicative inverter for home owners.

We no longer offer the ‘Lite’ model (Arc Fault protection, but no Data Manager).

Fronius inverters are efficient and reliable and form the indispensable heart of every photovoltaic system. Power categories ranging from 1.5 to 27.0 kW guarantee suitability for virtually any system size – from a family home to a large-scale system.
