Intergrated Inverter DC/AC Disconnects

Disconnects for safety reasons rapidly disconnect from a power source. Disconnects are on / off switches and are required by National Electrical Code (NEC). With a solar power system for your system to pass inspection and meet all UL and NEC requirements your system must have a DC/AC Disconnects.

Over the last few years inverter manufactures have been integrating dc, ac or DC & AC disconnects right into the inverter or as an external unit. Many inspectors are familiar with integrated DC / AC disconnects which is a good sign of the wide acceptance.

The picture above shows a SMA Sunny Boy Inverter with an integrated disconnect, a knob style switch quickly shuts off the power in case of an emergency.
