"Delta’s M15A and M20A Flex have a fan-less design and are cooled exclusively by natural convection. This makes them quiet and ideal for residential and small commercial buildings where low noise is a requirement," says Patrick Schahl, Product Manager of PVI Business Unit, Delta Electronics EMEA Region. "Aside from the technical features, customers value the importance of plant-relevant operating data, to understand their own carbon footprint, for example. Delta has extended the MyDeltaSolar app functionality and integrated a Wi-Fi module into the inverters that enables a direct connection to a smartphone or a WLAN router."
Increased profitability through outstanding reliability
Two MPP trackers and an input voltage range of 200 to 1000 VDC ensure optimum energy yield. The threephase inverters operate reliably and efficiently even at temperatures up to +50 ºC. To further increase reliability and prevent operational failures due to adverse installation conditions, the inverters are equipped with several key features: maximum voltage withstand up to 1100 VDC, arc fault detection and reverse polarity protection. The built-in anti-PID function prevents voltage-induced power degradation in crystalline solar cells, thereby extending their service life. In addition, replaceable AC and DC type 2 surge protection devices (SPD) are integrated; thus, string fuses are not required.
Simpler installation thanks to improved design
Installers benefit from the revised design and the low weight of about 40 kg. The mounting plate and AC and DC connectors are included.
