SMA_SB7000_Ad_ 090510 www.SMA-America.com The inverter is the heart of every solar power system. An inverter transforms the DC power produced by solar panels into utility-compliant AC power, allowing it to be fed into the utility grid. During the transformation process, it is very important that energy loss be minimized. SMA inverters reduce loss and maximize your solar system’s performance. SMA is the world‘s largest manufacturer of solar inverters and builds the most efficient, technologically advanced inverters available. When considering an inverter for your solar power system, SMA is the only logical choice. Ask for them by name.
