I have solar and a diy powerwall and emonpi
I have a standard type 2 charger outside for my hybrid now I just tend to charge when I see the solar is max but planning on getting an electric only car
with this in mind I want 100% of my excess solar to go to charging the car if its on the drive looks like evse can do this
do I need to replace the whole set up or is there a way to upgrade what I have already
It could be possible to upgrade your existing charger, but it will require a fair bit of work. A while back I upgraded an old Rolec unit to use OpenEVSE controller see video. The OpenEVSE controller will work with any AC contactor.
We sell all the OpenEVSE parts individually: EV Chargepoints (EVSE) - Shop | OpenEnergyMonitor
