Taiwanese inverter maker Delta has launched a new version of its M50A Flex solar inverter for applications in commercial PV projects.
The three-phase device has a power output of 50 kW, an efficiency of 98.7%, and a European efficiency of 98.3%. It is equipped with six MPP trackers and features an overall input voltage range from 200 V to 1000 V. “But the inverter withstands input voltages up to 1100 VDC without damage,” the manufacturer said in a statement.
The inverter measures 736x624x278mm and features an anti potential-induced degradation (PID) function and DC surge protection devices, as well data point collection for string monitoring and generation of I-V curves, reactive power compensation, arc fault detection, and reverse-polarity protection.
“The heavily revised mechanical design results in an improved IP66 protection degree, a significant weight reduction of 15%, to, now, 64kg, and more space for routing the AC cable inside the inverter,” the company stated, adding that the device will be sold in several, unspecified European markets starting from this month.
