Carlo Gavazzi demonstrate its latest energy portfolio at The Energy Event 2009

With the increasing demand for small-scale renewable energy sources, Carlo Gavazzi has introduced the new micro wind turbine solution. The Mistral comprises of a 3kW wind turbine, braking control unit and inverter to enable users to generate electricity for the home or office, and feed surplus energy into the public grid.

Power is generated by a horizontal axis wind turbine (HAWT), which offers high efficiency with a low level of audible noise. The 2.6m diameter propeller provides a sweep area of 5.31m² and is integrated with a generator. This 48.5kg unit makes use of lightweight, weather resistant materials: together with a specially-designed blade profile, it provides very high performance even in case of dominant wind turbulence. In harsh conditions, even when installed close to high buildings, this small turbine provides up to 39% of total efficiency. When the wind speed is more than 12.5m/s the safety “furling protection” tilts the mill tail, orientating the propeller diagonally to the wind direction, and forcing the propeller to slow down. In such condition the maximum power is also self limited to 3.3kW.

Launched at this event, the Eos-Array controller enables efficient running of PV plants to help meet the growing demand for green energy. Eos-Array is a versatile, reliable modular controller which enables small to medium or high power photovoltaic (PV) plants to meet the growing demands for clean sources of energy by maintaining efficient operation, maximising performance and strengthening the Return on Investment.

It is easy to install and configure and comprises individual modular elements that, when interacting with one another, provide a complete and independent control solution that gathers accurate and dependable data to ensure effective information management, and can be scaled up or down according to requirements and budgets.

Carlo Gavazzi’s MID-certified family ranges from an ultra-compact DIN-rail mounted single-phase 32A energy meter, up to three-phase 65A energy analysers offering built-in hot/cold water, gas and remote heating measurements and load monitoring.

The EM11-DIN is a compact 1DIN module that adds MID-certified power measurement and control functions to active energy metering. A single-phase energy analyser with built-in configuration push-button and LCD data display, it provides both active and reactive energy metering, together with cost allocation functions.

Also certified is the world’s first compact three-phase energy meter to boast a patented multi-application detachable display and dual mounting technology. The EM21-72D can be used either as a basic energy meter or multifunction meter and brings both simplicity and compactness to building management systems and cost-allocation applications.

Top-of-the-range EM26-96 1-2-3 Phase energy analysers feature a built-in configuration joystick and LCD data display. A comprehensive range of system and single-phase variable measurements is provided along with utility metering (energy, hot/cold water, gas, remote heating), and load monitoring with harmonic analysis up to the 15th harmonic. It is particularly suitable for import and export energy metering, and for cost allocation applications, as well as many more.
