Yes, car charging and water heating with Fronius equipment is pretty easy to arrange and can be prioritised for solar or cheap grid tariffs. There are simple relay outputs for switching loads as well as dynamic controls that work best with Fronius branded chargers and controllers.
Can I set up a priority between the Ohmpilot hot water control and the Wattpilot EV charger?
Yes, you can set up a priority or preference between the Ohmpilot and the Wattpilot. You can influence the priority of the Wattpilot through settings like the "PV battery limit value" and "Ohmpilot priority." The specific settings may depend on your system configuration. You can refer to the Fronius Wattpilot operating instructions and the Energy Management with the Fronius Wattpilot guide for more details. There's also a how-to video available on prioritization in the Solar.wattpilot app.
Are there any resources available for third-party control of Fronius equipment?
Yes, Fronius provides an OCPP interface for third-party control. This interface can be useful as the Distribution Network Service Providers (DNSPs) and retailers may require or incentivize off-peak charging in the future. You can learn more about the OCPP interface in the Fronius user information document linked below.
