Product details
Verto
Verto is a three-phase photovoltaic inverter with a rated AC output of 25–33.3 kW, depending on the model, designed for new and expanding PV installations. Four maximum power point (MPP) trackers simplify the configuration of complex installations, while the Dynamic Peak Manager algorithm optimizes yields under shading. Open interfaces enable integration with devices that use surplus energy for electric vehicle charging and heating.
Key advantages of Verto
- Four MPP trackers: two DC connections per system, a maximum usable current of 28 A at the MPPT input and a DC input voltage range of 150–1000 V.
- Optimization under shading: the integrated Dynamic Peak Manager algorithm supports the use of energy from the PV installation.
- 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, farm owners, and owners and managers of multi-family homes building or expanding a PV system. Four MPP trackers meet the needs of complex systems, while open interfaces make it easier to use surplus energy for heating or charging electric vehicles.
