The device with an output of 3.5 kilowatts can also control an external standard heating rod with three kilowatts, allowing outputs of up to 6.5 kilowatts to be realised in total.
Unlike its predecessor models, tradesmen can easily install the heating element in the storage heater without having to consult an electrician. This is because the heating element is initially still separate from the electronics unit.
The advantage of the new connection: The SonnenVPP virtual power plant bundles the home storage units and integrates them into the energy market. The intelligent control centre is the Sonnen home storage system - which can now also be networked with the Elwa 2 heating element. Technical details can be found in this guide. (nhp)
