SMA

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

The included "auto-sensing technology" makes the SMA 4000US more flexible and easier to install than ever. It will automatically detect whether the output voltage is 208VAC or 240VAC.

The Sunny Boy 4000US is designed to support solar panels in series, increasing efficiency and eliminating the need for expensive DC distribution systems and cabling. Each Sunny Boy inverter is equipped with a separate and autonomous grid monitoring facility that enables the user to hook up the AC output to any point within the electric distribution system of house.

Sunny Boy system diagnosis and control can be transmitted to your PC via many means. These include RS485 and Wireless. You can even view your system statistics on the internet! (with optional system monitor)
