Fronius Symo GEN24 Plus 8kW — Ireland 2026
Premium Austrian 3-phase hybrid — IP66, PV Point backup, BYD LFP integration
The Fronius Symo GEN24 Plus is the premium 3-phase commercial hybrid — the correct choice when IP66 weather protection, Austrian manufacturing quality, and PV Point emergency backup are required. IP66 is rated for dust-tight protection and resistance to high-pressure water jets — significantly better than the IP65 of most rivals. Critical for farm buildings, coastal commercial sites, exposed industrial units, and any installation where hosing down walls is routine. PV Point provides emergency solar power without battery on all 3 phases — unique in the commercial market.
