                Using excess solar over 2 phases with a Fronius Wattpilot
              
          
    Making use of two phase solar generation with a Fronius Wattpilot EVSE

I have a non-typical two-phase power supply with 4.8kW solar generation on each phase. Each phase has a Fronius inverter (with datamanager card) and smart meter on the grid import/export. It calculates the household load as the difference between the generation and export.
I have recently installed a Fronius Wattpilot EVSE to charge my electric car. The Wattpilot can operate on one or three phase power, in my case it is limited to single-phase operation since I do not have a three-phase power supply.
The Wattpilot can communicate with a Fronius inverter to determine the excess solar generation, and adjust the EVSE's power draw accordingly. The inverter reports the excess solar generation by observing the grid import/export on the same phase.
The Wattpilot can only communicate with one inverter, and because our inverters are separate systems on separate phases, it can only know about the excess solar on one phase. However, with net-

    How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.
Do not use self-signed certificates in production !
For online certificates, use Let's Encrypt instead (tutorial).
