@Edent Nice work. Interesting day. Solcast predicted 11 kWh for today. Crappy morning. With the rain, generated about 2 kWh. Solcast said 9 kWh left in the day at 12pm. I thought I might use Agile for an afternoon top up, but decided to trust Solcast. The battery is now 100% full. Agile has some minus slots tonight. Might charge the battery anyway Out of interest, what would you call a self sufficient day? When the solar generates more than the consumption or more than the import from the grid
