Mitsubishi Enters North American Large-Scale Inverter Market

Mitsubishi has just become the first Japanese company to enter into the North American inverter market. The company already produces solar panels, and with the addition of large-scale inverters to their product line, Mitsubishi claims that it will make installations easier than ever - at least for big solar installations. Mitsubishi now produces 100- and 250-kW inverters to be sold in the United States by Mitsubishi Electric & Electronics USA, Inc., headquartered in Cypress, CA.

Mitsubishi’s new offering has achieved a CEC-weighted efficiency rate of 97.5% percent, the highest in its class. The higher the efficiency of the inverter, the more energy that is converted into the AC wiring of the structure the inverter services. As an added bonus, the transformer-less inverter makes the unit lighter. A lighter inverter eases the stress on its mounting bolts during the inverter’s lifespan, something more likely to come into play in exterior applications.

Mitsubishi’s inverters are far too large for anything but a commercial application, but they will be capable of handling severe climates and being mounted indoors or out. The versatility of the inverter, as well as the option for a single manufacturer of its solar system, should help ease some of the stress of keeping multi-component systems serviced. Really, it’s easier to have one certified repair man fixing your matching appliances than different individuals certified to handle each brand.

A prototype of the 100-kW variety will be on display at the Solar Power International 2009 in Anaheim, CA from October 27-29. The 100-kW model is scheduled for an October 2010 launch and the 250-kW model scheduled for April 2011.
