SMA Adds a New Sunny Boy with a 10-Year Warranty

The Sunny Boy SB3300 by SMA America features a sealed, powder-coated cast aluminum enclosure that’s lighter and more rugged than previous models of Sunny Boy inverters. According to the company, the durable, lightweight design allows for installation in harsh environments and improves heat transfer. The enclosure keeps control and power electronics separate. The SB3300 introduces SMA’s Opticool airflow technology, which cools the power electronics by drawing air through the bottom of the enclosure. The SB3300 features a built-in meter that displays operational status and the amount of solar energy being produced. The SB3300 is designed for home use, and will operate with newer, larger PV modules. The SB3300 is compatible with SMA’s newest data communications options, including the Sunny Beam and WebBox.

Sunny Boy SB3300U Introducing the latest addition to the SMA line of Sunny Boys The latest addition to the Sunny Boy family, the new SB3300 inverter. Over two decades of engineering experience has culminated with the creation of the SB3300. Its new cast aluminum enclosure means lighter weight and better heat transfer for sensitive components. New construction and design techniques allow SMA to set the bar even higher when it comes to real-world efficiency and overall reliability. The new SB3300, evidence that the pioneering spirit is alive and well at SMA. Sunny Boy. Ask for it by name! Like its big brother, the Sunny Boy SB3800U, SMA’s new SB3300 watt inverter processes solar energy at an unparalleled 95.6% efficiency and is the second in a new generation of inverters to be released in America. These new SMA inverters incorporate a cast aluminum housing used to separate the control and power electronics. This new chassis design is incredibly rugged, lightweight and weatherproof. The power electronics compartment integrates SMA’s new Opticool (TM) airflow technology where cool air is drawn in through the bottom of the enclosure by convection, drawn around the power electronics where the air absorbs heat and is then released through a side vent. When required, this process is assisted by a temperature controlled fan. The built in meter displays system status as well as the solar energy being produced by the power plant and other key information on the LCD screen. Several meter and software options are available from your SMA supplier.
