I have been in the industry since 2008 when I started as SMA America's technical trainer. I bid SMA farewell in 2015 and hopped over to sonnen, Inc. to help them launch their energy storage system in the U.S. In May of 2021, I transitioned to Tigo as the Technical Training Director. I am a huge fan of renewable energy, BBQ, and gaming. I am a published author and wrote an Amazon best seller about grid-tied lithium-ion storage.
