Sunny Boy 3800U

SMA's new 3800 watt inverter processes solar energy at an unpararelled 95.6% efficiency and is the first of a new generation of inverters by SMA to be released in America. These new 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 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.
