Hello Wrenches, You may be aware of this but the -92R firmware supposedly has addressed the arc fault issue for the US-40 inverters. See here for the download: https://www.sma-america.com/service-support/downloads.html It fixed an arc fault issue for me yesterday at least. Bring a thumb drive, the update process took about an hour to perform.
