Has anyone got this combination to work allowing you to charge the car ONLY when you are exporting power to the grid?
Photovoltaics power the house, charge the battery, then export to grid if there is any left over.
Battery runs the house at night and can charge using off peak if needed. Current snapshot from my inverter:
The HEM allows for optimised charging using excess generated power - ie. charge your Taycan using excess solar power.
From the example image above, I'd like to send that 2.96kW to the Taycan instead of selling on the grid for a measly 8c per kWh.
Others have documented controlling the PMCC in similar situations but not with house batteries:

Unfortunately, the installation documentation doesn't consider a home battery system in the mix.
Everything else is working ok - timed profiles, direct charging. Was installed professionally by Jetcharge (Porsche charger installers for Oz).
