We’ve been doing some testing with the OpenEVSE solar PV divert, to help with this I’ve created 3 data samples from various types of solar PV days. I’ve posted the data below since it may be useful to someone else. Data is in CSV format in W with data time string: [day1 - 2khWp - variable output] …

@jeremypoulter has been using these solar PV data samples to simulate OpenEVSE solar PV divert: [Screenshot 2020-03-20 at 12.15.15] [Screenshot 2020-03-20 at 12.15.23] [Screenshot 2020-03-20 at 12.15.31] Work has begun on improving the OpenEVSE solar PV divert, these improvements will be back…

Nice work, so this change makes it only charge the car when there is solar export and stops at all other times? Does this work okay with Tesla model 3 ?

Yes and yes. It will work with all EV’s However, is not quite ready for release yet. Will be available soon as na OTA update for all EmonEVSE / OpenEVSE units. Solar PV divert feature is already supported but this takes it a step further.
