I give an update on my solar power system, covering the 18.2 Kw solar panel array mounted on the roof of my Barn, the 4 Growatt ES 5000 5Kw charge controller/inverters, 10 5.1KwH server rack batteries from EG4 and Jackiper. I have a Generac 21 Kw backup natural gas generator with an automatic transfer switch that runs off my onsite natural gas well. On a good sunny day I can charge my Rivian R1T full EV pickup truck and run everything in my Barn and charge my batteries. A good sunny day is rare this time of year in Western Pennsylvania.
