Delta’s M70A sting inverter has six MPP trackers that make configuring large and complex photovoltaic systems easier. They also boost output from arrays that experience partial shading. Compact dimensions and a high power density of 750 kilowatts per cubic metre at 400 volts make the M70A easy to transport and install. This new Delta inverter is targeted at commercial rooftop installations ranging from 70 kilowatts to as much as several megawatts.
The M70A provides flexibility for both system engineering and building design. The six MPP trackers offer 3 pairs of connectors each to provide more options when arranging module strings. This way, planners can compensate for shading and complex roof geometries by allocating the MPP trackers accordingly. If two strings are attached per DC input, neither external string breakers nor fuses are required. (mfo)
