I've automated several aspects of my PV/PW setup with the one remaining being to automatically set the PW reserve % based on expected solar production. For background, I'm typically running in self-powered mode with storm watch off and have no TOU; I'm separately metered for incoming vs outgoing from/to the grid with incoming costing more that what I am paid. Currently, I'll look at the weather.gov sky cover forecast for the next couple of days and determine where to set the self-powered % to ensure if the grid goes out there's enough power in the PW to carry over until the next solar producing day. Curious whether anyone has automated this and what data sources or algorithms are in use?
