Inverter – FRONIUS – Verto 27.0 SPD 1+2
Product details
Verto
Verto is a range of three-phase photovoltaic inverters for building new PV systems and expanding existing ones, with a rated AC power of 25–33.3 kW depending on the model. Four maximum power point (MPP) trackers facilitate the management of complex systems, while the integrated Dynamic Peak Manager algorithm optimizes yields under shading. Built-in protection and open interfaces support safe operation and the use of surplus energy for vehicle charging or heating.
Key advantages of Verto
- Four MPP trackers: two DC connections per system, a maximum usable current of 28 A per MPPT and a DC input voltage range of 150–1000 V.
- Optimization under shading: the integrated Dynamic Peak Manager algorithm helps maximize energy yield from the PV installation even under shading.
- Integrated protection: Arc Guard arc detection and interruption, DC/AC surge protection and leakage current monitoring.
- Efficiency: maximum efficiency is 97.47–98.03% depending on the model, and MPP efficiency exceeds 99.9%.
- Energy management integration: open interfaces facilitate integration with Fronius Wattpilot, Fronius Ohmpilot, heat pumps and smart home systems.
- Indoor and outdoor installation: IP66 protection rating and an ambient temperature range from -40 to +60°C.
Who is this a good choice for?
Verto is designed for small businesses, farms and multi-family homes planning a new PV installation or an expansion of an existing one. Four MPP trackers meet the needs of complex installations, while integration with vehicle charging and heating equipment allows users to make use of surplus solar energy. Companies with an electric vehicle fleet can add Fronius EMIL to their installation to automatically power the fleet across the entire site.
