Direct Grid Technologies, LLC has announced a new series of OEM grid‐tie micro‐inverters that mate to a variety of monocrystalline and polycrystalline type modules. The DGM‐S250 offers a power output of 250 watts, and the DGM‐S460 offers an unprecedented 460 watts. Similar to its predecessor, the DGA Series, the DGM Series units use Direct Grid’s unique closed-loop MOSFET planar architecture, which offers high power and excellent thermal management—resulting in unparalleled efficiency and reliability. The DGM‐S250 is designed to mate with a single 60 cell 210‐240 watt module while the DGM‐S460 is suited to mate with a two 60 cell 210‐240 watt modules. For original equipment manufacturers, power tracking voltage inputs can be modified to suit custom maximum power point ranges. The SMART DGM Series also includes Echelon communication that permits each micro-inverter in the network to communicate with a remote access node. Power data, temperature, diagnostics, and unique identification code are routinely collected from each micro‐inverter, and this network communication provides theft deterrence. The resulting data can be graphically presented to end-users for easy system monitoring. Certifications targeted for the DGM Series will include UL1741/IEEE1547, VDE 0126, FCC Part15, and CE.
