  Delta Puts Spotlight on New High-Efficiency Flex Series 3-Phase Inverters and High-Power Solar Inverters at Energaia 2021
Delta, a global leader in power and thermal management solutions, will be present at Energaia 2021, hosted at the Montpellier Exhibition Centre from December 8–9. The focus of its presence at the exhibition will be the new Flex series, which now includes four new inverters: the M15A, M20A, M30A, M50A and the new M100A. All have been engineered to be highly reliable and capable of fulfilling multiple application requirements, extending from residential to commercial. Another highlight will be the brand new M250HV, which offers input voltages from 550 to 1500 VDC and has been designed specifically for large ground-mounted PV plants.

Full range of Flex series three-phase inverters for a multitude of applications

The Flex series family has been expanded with the addition of four new three-phase inverters: the M15A, M20A, M30A, M50A and the M100A. With their design concept inherited from the M70A Flex, the whole series is highly reliable and compatible with multiple applications. The M50A is a technological twin of the M70A. This benefits customers by making it easy to integrate both inverters into large rooftop installations. Additional key features include six MPP trackers for up to 12 DC strings for the M50A, optional DC SPD Type 1+2 and ground mounting as well as a wide input voltage range.

The M100A is an evolution of the M70A with additional key features including eight MPP trackers for up to 16 DC strings, optional DC SPD Type 1+2 and ground mounting as well as a wide input voltage range.

To ensure a fast installation, the M15A, M20A and M30A Flex inverters feature an AC-plug solution, Wi-Fi connectivity for easy integration into a WLAN, and three MPP trackers for the M20A and M30A to allow more flexibility in the design of the PV array. Combined, these features make the Flex inverters an ideal solution for residential and small commercial PV plant applications.

M250HV – The ideal solution for super-large ground-mounted PV plants

The new 250 kW string inverter - with input voltages from 550 to 1500 VDC – has been designed specifically for massive ground-mounted PV plants in the upper megawatt range. With the M250HV, up to 30 DC strings can be connected to its 12 MPP trackers. Handling of heavy AC cables is made as easy as possible thanks to the spacious AC Connection box. "The development of the M250HV benefits from our extensive experience in the field of inverters for utility-scale photovoltaic systems," commented Andreas Hoischen, senior director of Photovoltaic Inverters Business Unit at Delta Electronics EMEA region. "Customers benefit from a compact, easy-to-install and low-maintenance inverter designed to operate reliably even under the harshest environmental conditions."

Additional features - such as Anti-PID and Pro-EL (Electroluminescence) functionality - detect problems with PV modules, helping EPCs to keep their PV systems operating at the highest and most efficient levels.
