The SB4000US has an integrated DC disconnect and an AC disconnect that makes installation easier and more cost-effective. This inverter is field configurable for negative or positive ground systems, this makes it more versatile than other grid tie inverters.

The auto-sensing capability makes the SMA SB4000US more flexible andeasier to install than ever. It will automatically detect whether the output voltage is 208VAC or 240VAC.

The SMA US Series is optimized for solar PV modules in series, increasing efficiency and eliminating the need for expensive DC distribution systems and cabling. Every US series inverter is equipped with a separate and autonomous grid monitoring facility that enables theuser to hook up the AC output to any point within the electric distribution system of house.

Increased efficiency of up to 96.0% means better overall performance and shorter payback periods. All SMA inverters are engineered and built to last. The SMA SB4000US has a standard 10-year warranty. SMA Sunny Boy inverters are trusted worldwide. This inverter line is housed in a water tight stainless steel NEMA 3R outdoor enclosure. The SMA US Series can operate in extreme conditions(ambient temperatures of -13ºF to +113ºF). They can be mounted right behind the solar module array on the roof, on a wall, or even on the ground.

Features:
  • Highest CEC efficiency in its class
  • Integrated lockable DC disconnect switch (load-break rated)
  • Integrated fused series string combiner
  • Sealed electronics enclosure with Opticool
  • Comprehensive SMA communications and data collection options
  • Ideal for residential or commercial applications
  • 10 year warranty
  • UL 1741/IEEE-1547 compliant
