Features Application Technical data sheet

General System Characteristics

Hybrid technology: integrates solar modules and vertical axis wind turbines into a single, optimized system.

Energy storage: equipped with a high-capacity lithium-ion batteries and Battery Management System (BMS).

    • Battery capacity (example): 2 x 10 kWh (total 20 kWh).
    • Battery life: Approximately 7-8,000 charging cycles.
    • Battery warranty: 5 years.
    • Battery operating temperature range: Between -20 °C and +60 °C.

Power: available in several nominal power categories (i.e. 5 kW, 7,5 kW).

High energy efficiency: optimized operation for maximum energy recovery.

Remote monitoring and control: operation can be monitored online via an internet connection, detailed statistics and remote intervention options via an application.

Intelligent operating system:

    • It manages the various energy generation units (solar panels, wind generators) and the network connection.
    • It automatically regulates the direction of energy flow based on programmed priorities.
    • It allows direct power supply to the network or power supply from the network.
    • It can feed energy into the batteries or the grid according to priority.

Long lifespan: the expected lifespan of the main components > 20 years.

Minimal maintenance: the wind generator requires maintenance once a year.

Continuous operation: the special design and hybrid technology (solar, wind, battery) enable a constant energy supply.

Predictable return on investment: thanks to the nano-coating (optional) and high operating hours.

Characteristics of vertical axis wind turbine

Rated power: 5 kW

Maximum power: 7.5 kW

Dimensions: rotor diameter 3 m, rotor height 3 m

Quiet operation: virtually silent, making it ideal for use near residential areas

Bird-friendly design: poses no danger to birds

Storm-proof: capable of operating safely in stormy weather conditions, does not require shutdown, does not spin out of control (equipped with automatic two-stage braking system)

High efficiency: uniquely high energy production efficiency that does not decrease over the lifetime

Operating range: delivers its rated power even at medium wind speeds

Features of the solar panel system

Panel type: DAH Solar Solar Panel DHT-M60X10 / FS FULL SCREEN Black Mono

Panel rated power: 460 W

Solar system power: 4.6 kWp

Expandability: the surface area of the solar panels and thus the system output can be increased as required

Nano coating: contributes to maintenance-free operation and predictable returns

Expected lifespan: > 20 years
