Austrian startup offers hybrid PV-wind system for off-grid applications

Austrian startup Novventos Clean Energy has developed a container-based hybrid power system combining photovoltaics with small vertical-axis wind turbines. The system is designed to supply decentralized electricity for off-grid and temporary applications, with a common energy management system controlling both generation technologies.

Modular PV system for ISO containers

Founded in 2023, Novventos Clean Energy has developed the “sky.boost” PV system with a modular architecture designed for installation on ISO containers. According to the company, the system can be assembled within a few hours.

The second generation component is the “naca.boost,” a small vertical-axis wind turbine designed for installation at heights of 3 meters to 8 meters. The manufacturer says the turbine can harness turbulent airflow close to the ground, where conventional wind turbines may be less suitable.

A fairing directs the wind toward the rotor. The wind component is intended to complement PV generation during periods of low solar irradiance. According to Novventos, two naca.boost turbines can generate 12,000 kWh of electricity, while the PV component produces an average of 3,400 kWh. The company does not specify the period over which these generation figures apply.

Shared management system for solar and wind

The PV and wind components are controlled by the company’s “master.boost” energy management system, which monitors the output of both technologies and manages energy distribution.

Generation and operating data are also centralized on the company’s cloud platform and can be accessed through a web-based interface.

Novventos combines the components in a container-based system marketed as “mobile.energy.” The company says the system is intended for off-grid locations and temporary applications and can also be supplied with an optional trailer.

Limited technical data available

Novventos has not provided detailed technical specifications for the complete system. In particular, the company does not state the installed PV or wind power capacity, making it difficult to assess the stated electricity-generation figures.

The company also does not mention battery storage as part of the mobile.energy system.
