Fronius Primo GEN24 Plus 5kW — Ireland 2026
Austrian premium hybrid — PV Point solar backup without needing a battery
The Fronius Primo GEN24 Plus is the premium residential hybrid inverter in Ireland and is unique for one compelling reason: PV Point. This exclusive feature provides up to 3kW of emergency backup power from solar panels alone — even with no battery installed. When the grid goes down, the inverter automatically creates an island, drawing power from your panels to keep essential circuits live. Austrian manufacturing, 98.0% efficiency (the highest single-phase residential figure in this directory), and the Fronius Solar.web monitoring platform complete the package.
