SMA AMERICA SMA America is preparing to release its first ever micro inverter this fall. The Sunny Boy 240-US is said to be ideal for residential hybrid Sunny Boy string/micro instal- lations and systems with complex shading. The micro inverter offers simple installation and reliable performance with high efficiency, as well as a simplified design and flexibility to enhance long-term reliability, according to SMA. The Sunny Boy 240-US will come with the Sunny Multigate- US, an integral component of the micro inverter system. The Multi- gate will serve as a multi-purpose connection point that provides clear communication and user- friendly electrical interface to the main service panel. The Sunny Boy 240-US will include SMA’s trademark reliability, performance, and customer support. www.sma-america.com DIRECT GRID Direct Grid’s ARRA-compliant DGM-S460 GEMINI Series utility grade grid tie micro-inverters employ what the company says is a unique planar transform- er design that offers the highest power density, low operating tempera- ture, and unsurpassed reliability. With an indus- try leading 530W power, each micro-inverter accepts DC power from a pair of many popular 60-cell photovoltaic modules and converts it to grid compliant AC power (208VAC or 240VAC, 60Hz or 230VAC, 50Hz). Combined with the auto-grid synchronization (which drives a power factor > 0.99), use of the DGM-S460 micro-inverter results in energy harvest gains of five to 25 percent versus conventional centralized systems, says the company. Each unit incorporates robust PLC communications that send a collection of power, diagnostic, and unique ID data to a remote gateway device. The gateway fre- quently transmits the harvested data to a remote server via an Ethernet connection. Users can easily monitor each unit’s performance and health 24/7 through the WattTrack web interface. www.directgrid.com ADVANCED SOLAR PHOTONICS Advanced Solar Photonics’ (ASP) grid-tied PV invert- ers offer an efficiency and voltage operating range that maximizes energy yield and return on investment, according to the company. Installation time and costs are reduced through an integrating combiner box, AC/DC discon- nects, and wire raceway. The design simplifies service on the unit through a two-piece modu- lar configuration that allows the wiring box to remain connected and mounted if the power module needs to be replaced. Ratings are 3800W, 4000W, 5000W, 6000W, and 7000W. Features include: • 97 percent CEC efficiency • Broad voltage operating range (105-500 Vdc), performs in low light and high temperature • Transformerless design • Integrated PV system AC/DC disconnect switch • Four branch circuit-rated negative and positive fused inputs • Integrated NEC-compliant wire raceway • Field selectable voltage output: 208/240/277 Vac • LCD display with nighttime monitoring capabilities • NEMA 3R enclosure • ETL listed (compliant with UL1741 standards) and CEC listed (in process) www.advancedsolarphotonics.com INVERTERS enerG Focus Feature 50 enerG I September/October 2012 I www.altenerG.com Learn more at: eaton.com/solar Harness the power of the sun Introducing the new Eaton Power Xpert™ Solar 1500 kW Inverter
