Delta's new technology three-phase M50A Flex solar inverter provides extra flexibility in system design – PRNewswire

"As we see a growing trend to have solar panels on rooftops for commercial buildings, the Delta M50A Flex is designed for versatile commercial rooftop applications. With its advanced features to get more energy out of your PV roof and additional safety features like arcing faults and die Reverse polarity detection simplifies the work of EPCs, makes solar systems simpler and safer, and improves energy costs for commercial building owners, "said Andreas Hoischen, senior director of Delta EMEA's photovoltaic inverter business.

Flexible design of the PV roof system

With its six MPP trackers, the M50A is primarily geared towards complex roof installations and offers the system designer more flexibility in the arrangement of the modules and the distribution of the module strings. In addition, the entire input voltage range is between 200 and 1000 VDC, but the inverter can withstand input voltages of up to 1100 VDC without damage.

The system operator benefits from the anti-PID (Potential-Induced Degradation) function by avoiding this negative effect and the resulting power losses in the solar modules. Relevant for lightning protection on building roofs are the newly available AC + DC surge protective devices (SPD) type 1 + type 2, which can optionally be ordered as a replacement for the pre-installed type 2 SPDs.

Other new and interesting features and functions are data point acquisition for monitoring strings and generating I-V curves, reactive power compensation around the clock, detection of arcing faults and reverse polarity protection.

The M50A Flex is equipped with the standard RS485 interface and also offers an integrated wireless Sub-1G communication port and optional WLAN.

Improved form factor, less weight, easier installation

The heavily revised mechanical design leads to an improved degree of protection IP66, a significant weight reduction from 15% to 64 kg and more space for laying the AC cable in the inverter.
