What Are the Specifications for an SMA 3000 Inverter?

• Solar inverters, a component in solar power systems, change the direct current generated by a solar module into the alternating current power used in homes and businesses. These devices also monitor yields and manage solar grids. SMA America, a subsidiary of the German company SMA Solar Technology, specializes in the manufacture of inverters, including the Sunny Boy 3000-US, which comes in 208- and 240-volt models.

Input and Output Specifications

• SMA America's Sunny Boy 3000-US features a maximum direct current input of 3,200 watts and 500 volts. The 208-volt model possesses a minimum DC voltage of 175 while the minimum DC voltage of the 240-volt model is 200 volts. For both models, the start voltage is 228 volts.

  This inverter outputs 3,000 watts of alternating current. The 3000-US 208-volt model has an AC voltage range of 183 to 229 volts. The 249-volt model has an AC voltage range of 211 to 264 volts. The 208-volt model inverter runs at a 96 percent maximum efficiency level while the 240-volt model runs at 96.5 percent maximum efficiency. The unit can operate in temperature ranges from minus-13 to 113 degrees Fahrenheit.

Physical Specifications

• The body of the SMA Sunny Boy 3000-US model inverter is made of die-cast aluminum. The inverter unit measures 17.8 inches wide, 13.8 inches high and 9.3 inches deep.

  The unit's DC disconnect enclosure, an appendage, measures 7.3 inches wide, 11.7 inches high and 7 inches deep. SMA's 3000-US inverter weighs a total of 84 pounds. The DC disconnect unit clocks in at 8 pounds.

Features

• The SMA Sunny Boy 3000-US inverter features a Bluetooth-compatible interface and displays data via text lines and graphics. For installation, the 3000-US uses automatic grid voltage detection alongside an integrated DC switch disconnector. The inverter uses an OptiCool system for cooling and emits 40 decibels of sound, which is quieter than electric transformers. Underwriter's Laboratories -- an organization that tests consumer-market electrical devices to meet government-mandated safety standards -- certifies this device. The 3000-US works with all modules and features DC reverse polarity protection, AC short circuit protection and a galvanically isolated pole-sensitive monitoring unit.
