Direct Grid announced today the development of a new dual module 480W micro‐inverter product which it will be showcasing at Inter Solar North America at the Moscone Center in San Francisco July 12‐14th, booth 7552. The Gemini Series micro‐inverter allows photovoltaic design engineers to utilize half the number of micro‐inverters in an array, when compared with conventional 1:1 micro‐inverter designs, by connecting two modules per Gemini micro‐inverter.
Once again, Direct Grid extends its industry lead in total power density by offering a market leading “utility grade” micro inverter, 240VAC, 60Hz with a maximum output of upwards to 530W. While the Gemini was designed for the ultra‐rigorous physical and power level requirements of the utility sector, it is also embraced by the commercial/industrial market, due to the obvious economic advantages of only having to purchase 50% of the micro‐inverters for a given design. Initial certifications on the Gemini Series include compliance to UL1741/IEEE1547/CSA for the North American market.
With the Gemini series, the highest power commercial or residential solar modules can be easily connected to the unit in pairs, without any concerns of power limiting. Additional benefits include deployment of fewer modules to achieve desired AC harvest, lower line losses, lower installation costs and higher system reliability ‐ all without significantly detracting from harvest gains associated with individual maximum power point tracking (MPPT). Additionally, unlike most competitive products, the Gemini Series micro‐inverter is both frequency flexible and “self tuning” with regard to grid frequency, so it can serve both 50Hz and 60 Hz grid‐tied application segments.
