Just writing to thank Dacian and the forum, since my system is tentatively up and running.
I managed to keep all of the smoke inside the SBMS0, despite being the type of person who tends to make simple mistakes. I have installed half of my panels so far. My wiring is a total mess, but I'll improve it. No loads have been connected, other than verifying that the inverter turns on.
Two cloudy winter days have delivered a bit over 7 kWh, and my battery is still at 3.35V/cell. I hope to top the battery up tomorrow. I have not done a parallel top balance or capacity test yet. I was glad to be able to connect the SBMS0 to my wifi, despite a pretty weak signal in the shed.
I have found both the official manual and Oberon Robinson's beginner's guide to be invaluable. Anyway, lots more work to do and probably questions to ask, but thanks for the slick products and first-class support.
