Can anyone suggest a simple solar diverter (preferable prebuilt) to send unused (1.4KW) energy to an emmersion or oil filled radiator prior EV charger startup that will work alongside OpenEVSE and Emonpi
Robin Emley (mk2pvrouter.co.uk) might be able to oblige with a kit, unfortunately CE rules prevent him from selling a complete unit.
I don’t know the position with the (new & updated) French version (mk2pvrouter.com) which is based on Robin’s design.
