SMA has announced the availability of its Disconnect Unit, which provides additional safety and increased serviceability to any large-scale photovoltaic (PV) system. SMA's UL-Certified Disconnect Unit fully complies with NEC 2011 safety standards and is compatible with Sunny Central inverters in 600V to 1000V arrays.

"In addition to the exceptional protection that it provides, the Disconnect Unit is specifically made for use with PV inverters," said Jurgen Krehnke, president and general manager of SMA America and president of SMA Canada. "Its pre-engineered design eliminates the need for separate DC and AC disconnects intended for general electrical purposes."
