Im running 5 x Pylontech US2000 batteries and a Sofar ME3000 battery inverter. I changed over to Octopus Agile recently and want to make best use of the cheap rates during the night.
I have a few scripts running on the pi that set the inverter to charge the bank between 1am and 4am. I currently manually set a target SOC% based on the sunshine duration the following day. It seems to be pretty accurate; 6.7hrs of sunshine and I make between 6.5 - 7.0kWh from the solar.
I want to automate this process but cant find a weather source with a sunshine hours forecast. Any suggestions. I tried metrogroup (the data source for the app WeatherPro) but I cant find any useful information.
