[Fort Collins, CO] In 2012, REFUsol brought one of the early UL-listed 3-phase string inverter product lines to the US market. US-based Advanced Energy acquired REFUsol’s US product line in 2013, before exiting the inverter market altogether in 2015. REFUsol is currently a REFU Elektronik GmbH division under parent company German Prettl Group. Prettl Energy North America operates a US sales office in Fort Collins, Colorado. Two REFUsol 3-phase inverter models are available in the US, the 24 kW 24K-UL-USA and the 48 kW 48K-UL-USA. Both models feature natural convection cooling, 3-phase 480 Vac output and a maximum dc voltage of 1,000 Vdc.
