Fronius Verto 27.0 is a robust 27 kW three‑phase grid‑tie PV inverter engineered for commercial, agricultural and multi‑unit rooftop installations. With four independent MPPT trackers and full AC/DC surge protection (SPD 1+2), it delivers flexibility for complex roof arrays and optimal power yields even under partial shading. Packed with modern connectivity (WLAN/LAN/RS485) and installed in a rugged outdoor‑rated housing, this inverter is built to integrate seamlessly into monitoring, energy‑management and smart‑building systems.
Key Features
-
27 kW nominal AC output; designed for three‑phase grid‑tie systems (400/230 V and variants).
-
Four MPPT trackers enable flexible string design for roofs with varied orientations or shade.
-
Wide DC voltage window: 150 V start, up to 870 V MPP; accommodates high‑voltage PV string design.
-
Built‑in AC & DC surge protection (SPD Type 1+2) plus arc‑fault detection support for safety compliance.
-
Connectivity and smart features: integrated web server/data‑logger, WiFi & LAN, RS485, Modbus TCP, JSON interface.
-
Weather‑resistant, outdoor‑capable design with active cooling and a high ingress‑protection rating (IP66).
