YouTube channel "Transport Evolved" let me know about this:
I have three but ordered two controllers. If it works as I expect, it should let me integrate my Solar Project controller to adjust the charging rate to match the solar panel power. This will be totally awesome as it means all of my EVs will be charged at exactly the rate power is available without having to 'dip into the grid.'
