I don't have a lot of experience with those inverters. How many cycles do you drop when switching over?
My first idea was to create a system that watched the immediate price as well as the day ahead AND the weather forecast to try and predict the best time to stay off the grid, but that's a little too ambitious.
My current idea is to grab my 5-minute history over the last year or two and model it against a simple buy-low-sell-high threshold. It should at least tell me how much the system would save each month.
(BTW about your earlier post, even if supply is 1c/kWh, there's still the delivery charge and taxes. I think supply needs to drop to something like -3.5c/kWh before the juice is "free". It's happened only once or twice in my history with the system.).
