If you do find time along the way, Kirk, I'll join the queue to give it a read. While I've just been putting in 70 meters of 40 mm fire main and hydrants around my new build, there'll be solar panels on the 40° equator-facing roof skillion in the coming months, and maybe a couple of Redflow ZnBr redox batteries. They talk Modbus. We'll have to see what actually goes in. Some simple LiFePO4 batteries might be a noticeably cheaper interim solution, just with a shorter life.
