Enecsys has officially introduced its new SMI-D480W-60, 480W micro-inverter, which affixes to the railing system and can receive DC input from two independent solar modules. The Duo micro-inverter allows maximum power point tracking from both modules and is said to diminish the inverter cost in comparison to the one micro-inverter per module model.
The 480W unit takes the DC power produced by the two solar modules and transforms it into the compatible AC output. It holds a maximum input current of 24A and a peak efficiency of 96%, with a Euro efficiency of 94%. Contained in an IP66-rated enclosure, the micro-inverter weighs 4.6lbs and features a main body measurement of 9.6in x 6.29in x 1.57in.

Enecsys advised that its Duo micro-inverter carries a 20-year limited warranty and can operate in conditions ranging between -40 to 185 degrees F. The inverters have undergone several tests including thermal cycling to IEC61215 and have met CE, En 62109 and EN 6100-6 safety and EMC standards. The new inverters carry UL1741 certification, which is necessary for entrance into the US and Canadian markets.
Every SMI-D480W-60 micro-inverter includes a built-in wireless communication system so that performance data for the connected solar modules can be monitored in real-time. The micro-inverters are slated to become available in Q3 2011.
Enecsys CEO, Henrik Raunkjaer, commented, “The Enecsys breakthrough in creating an inverter with a service life to match that of solar modules now has even more appeal to customers as the capital costs are now comparable with those of string inverter systems. Under these circumstances, there is no logical reason why anyone would want to deploy a residential or commercial solar PV system based on string inverters when the advantages of micro inverters have been so clearly demonstrated.”
