Fronius Primo 5.0 Inverter

The Fronius Primo 5.0 is compliant with NEC 2014 AFCI requirements. Arc fault circuit interrupters, or AFCIs, are devices that provide a higher level of protection by detecting hazardous arcing conditions and shutting down the electricity before a fire can start. To comply with the new National Electrical Code® (NEC) requirements, the Fronius Primo inverter line has proprietary built-in arc fault circuit interruption (AFCI) to detect and extinguish an arc fault, and can notify the system operator that the incident occurred.

Fronius transformer inverters use a high-frequency (HF) transformer. The automatic transformer switchover facility produces three efficiency peaks. The result: a constant level of efficiency across the entire input voltage range, resulting in higher yields. Other advantages of HF transformer technology are the compact, lightweight design, a high level of efficiency and safety as a result of the electrical isolation.

The foundation of the unique PC board replacement is laid as we develop our inverters, as PC boards can only be replaced if the device has been designed accordingly. This enables our Fronius Service Partners to provide the fastest inverter servicing on the market.

Fronius Primo inverters are ready for the Smart Grid. It is optimally equipped to meet the technical requirements of modern utility grids. A series of smart functions, known as Advanced Grid Features, are built into every Primo inverter. These include a number of control functions for optimum feed-in of reactive power and effective power. These functions are designed to enable stable grid operation even when the PV system density is very high and to prevent unwanted interruptions to feed-in and associated yield losses. Fronius inverters therefore help to guarantee the yield of any home solar system.
