SMA SB Inverters

The SMA Sunny Boy inverters are designed to support PV modules in series, increasing efficiency and eliminating the need for expensive DC distribution systems and cabling. The Sunny Boy inverters increase efficiency further because they run a separate MPP tracking for each single string. 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.

One high voltage series string of solar modules can be connected to each inverter, vastly simplifying design and installation. The result is no mismatching from parallel connections and maximum Power Point Tracking for every series string. System expansion is easy - simply add more inverters and series strings of solar modules.

Sunny Boy system diagnosis and control can be transmitted to your PC via the AC power line using the optional Power Line Carrier Modem and is accessed through free Windows software. RS-232 and RS-485 communications modules are also available.
