SMA’s new Sunny Boy 3300U PV inverter now comes with a DC disconnect and 4-string fused combiner - standard. Over two decades of engineering experience has culminated with the creation of the SB3300U. 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 fficiency and overall reliability. The new silver lid and near silent operation will please even the most particular users. The new SB3300U, evidence that the pioneering spirit is alive and well at SMA. SMA’s new 3300 watt inverter processes solar energy at an unparalleled 95.6% efficiency and is the second 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 For added convenience, the SB3300U now comes complete with a DC disconnect with an integrated 4 string combiner. The DC switch is rated for load-break with provision for lockout. 4 string fuses mounted in individual fuse holders provide string overcurrent protection and assist is string trouble-shooting. The DC disconnect enclosure contains 1/2, 3/4 and 1” knockouts for ease of installation. 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.Specifications Inverter Technology Real sine-wave, current source, high frequency PWM AC Input Voltage 183 - 229 (208 V) 211 - 264 (240 V) AC Input Frequency 59.3 - 60.5 (60 Hz) AC Maximum Output Power @ 45°C 3300W @ 240 VAC 3000W @ 208 VAC AC Maximum Output Current 16 AAC DC Maximum Input Voltage 500 VDC DC MPPT Voltage Range 200 - 400 VDC @ 240 VAC 180 - 400 VDC @ 208 VAC DC Voltage Ripple < 10% DC Maximum Input Current 20 ADC PV Start Voltage (Adjustable) 264 VDC @ 240 VAC 229 VDC @ 208 VAC Recommended PV Power 4200 Wp Max.
