yea, let me work on getting screenshots. There's a ton of other settings like reactive power, CosPhi that
@robwolff3 called out in his post
I didn't change any of that, but I can confirm my SE retained the Grid Rule 21 setting between power cycles. Also the SE web interface is labeled as "Inverter SetApp" so I have to assume they are one in the same. I just wired in my home office to the critical loads panel today so I can start to draw down the battery overnight. One thing I've noticed though, not sure if it is normal or not - now that my batteries are 100% I am hearing the relays in the 18k click over every few minutes and the LCD shows a few hundred watts going to the batteries, relays click and it stops charging and the "Normal" status LED actually turns off when it's not dumping power into the battery... seems to be in a loop. Need to get the wifi dongle online next.
