Leading Solar Inverter Manufacturer Showcases New Product Portfolio and Complementary Intelligent
Functions in Hall 1, Booth L10.
Metzingen/Germany, October, 14, 2013 – REFUsol, an Advanced Energy company and leader in solar inverter
technology, is exhibiting at RENEXPO Poland, taking place October 16-17, 2013 in Warsaw, Poland.
REFUsol/Advanced Energy will display its proven three-phase string inverter series, showcasing a recent
design upgrade as well as the large scale inverter REFUsol 333K featuring higher AC- and DC-voltages
resulting in lower Levelized Cost of Energy (LCOE).
One of the highlights of the REFUsol/Advanced Energy showcase is the upgrade of its proven three-phase
string inverter series REFUsol 008K – 020K. The reliable inverters are upgraded to full power classes with
lower weight and therefore provide a high power density and easier installation.
The inverters are ideal for rooftop and carport systems from 8 kilowatts (kW) to megawatt-sized parks. Even at
low irradiation, they achieve an efficiency of up to 98.2 percent, maximizing economic return. As a result of
these high efficiency levels, convection cooling is all that is needed to dissipate the heat. The integrated datalogger can send all important operating data to the REFUlog internet portal. For visualization and evaluation
purposes, data can be transferred via the standard cable or an optional wireless connection using the new
REFUconnect radio module.
With 333 kW of nominal power and the patented UltraEta® circuit topology, the solar inverter REFUsol 333K
reaches a peak efficiency of over 98.4 percent, which allows for optimised energy conversion and usage. The
REFUsol 333K features a higher AC-voltage of 690 volts (V), which is the established standard voltage level
in industrial networks and wind power plants. It also features a higher DC-voltage of up to 1500 V. Due to this
high input voltage, longer strings can be realized, which means less loss with the same power lowering
installation costs and LCOE. Consequently, this concept of higher voltages increases the efficiency of the
whole photovoltaic (PV) system, increasing the financial return to the owner.
Additionally, the company’s single-phase string ranging in size from 1.8 kW to 4.2 kW will be on display.
These new string inverters are particularly suitable for small rooftop systems or for expanding larger systems
(for example, in case of shading). Even a
