Fronius Verto 33.0 is a powerful three-phase 33 kW grid-tie PV inverter tailored for commercial, agricultural and apartment‐building solar installations. Featuring a wide DC input window, multiple MPPT trackers, integrated surge protection (SPD Type 1+2) and full connectivity (WLAN, LAN, Modbus), it excels in complex roof layouts, partial shading and high-yield environments. Built for outdoor use (IP66 rating) and backed by the Fronius safety & monitoring ecosystem, it offers both robust performance and system-integration flexibility.
Key Features
-
33 kW nominal AC output for demanding solar systems.
-
Four MPPT trackers (in the 27/30/33 kW category) allowing flexible string design and improved shading resilience.
-
Wide MPP voltage range (150 V – 870 V) and high max DC voltage (1 000 V) for high‐voltage module compatibility.
-
Integrated AC & DC surge protection (SPD Type 1+2) and arc‐fault detection (AFCI) enhance safety and reduce additional hardware.
-
Full connectivity (WLAN, LAN, Ethernet, Modbus TCP/RTU, JSON) for seamless monitoring and integration with energy‐management systems.
-
Robust IP66 outdoor‐capable housing, active cooling system and wide ambient temperature range ensure reliability in harsh conditions.
