A2: XT stands for eXTended and consists of several features, including the possibilities offered by MV (multi-voltage). This allows single-phase devices from 96 to 265 V to be supplied with power.
XT also stands for optimal generator compatibility.
The integrated Power Factor Correction (“PFC” for short) improves the power factor and reduces losses such as reactive power or interference, making the XT versions even more energy-efficient.
