Fronius and BYD Battery Backup - Blackout Real-world Test

A recent weeklong power outage saw my family and I perform the ultimate real-world test on our Fronius inverter and BYD battery backup system. The outage occurred between Christmas and NYE during a time when we had family visiting meaning there were 14 people in the house all vying for the valuable energy. In this video I walk through the experience both good and the bad and things we learned along the way.
