The 2 Fronius IG 4000 4 kW inverters on my buddy Larry's 2007-era solar system were going kaput, so I installed 2 brand-new SMA Sunny Boy 6.0-us inverters (SB6.0-1SP-US-41) to replace them. At the same time, i decided to open up the Tesla Powerwall gateway Solar City put in around 2017 and take a look at how it operates. "Commissioning" the new inverters is also covered. 00:00:00 Introduction 00:03:51 Tesla Gateway Tour 00:08:46 Inverter Swap 00:10:52 Inverter Commissioning #solar #pv #tesla
