Thanks for this guide. Very usefull!

Thank you, although I didn't understand SCO settings

Thanks you. Why are there no fuses or isolators drawn between the B-Box pro and the SI? What is the fuse rating recommended for a single B-Box 13.8 and what is the rating for 5 in parallel? Whilst BYD recommends parallel connection of B-Boxes, it seems that the maximum number of units that can connect to SI8.0 is 2. In other words, am I limited to maximum 2xB-Box Pros in parallel connecting to single SI8.0H?

excuse me, I have 13 battery units (100ah) that I installed in parallel into 1 battery bank. so if I want to set the system on Sunny Remote Control on the battery menu, do I have to fill in the current description of the battery as much as 100ah or 1300ah?
