Which my-PV solution fits your project?
Use PV surplus: AC ELWA 2 combines control and heating rod. AC•THOR and AC•THOR 9s control separate suitable heat generators. The appropriate surplus information comes from the my-PV WiFi Meter or a supported system.
Heat directly with PV direct current: ELWA contains a heating rod; SOL•THOR controls a separate heating element. Both use a suitable PV generator. A mains connection is necessary for the optional hot water protection.
Use dynamic electricity tariffs: HEA•THOR IoT can also be used without its own PV system. Tariff optimization via my-PV Cloud and DTO requires appropriate services and a suitable electricity tariff; costs and functionality have to be clarified separately.
Check memory and connection: Threads, installation length, electrical supply, temperature guidance and existing components determine the selection. Heating power is not a statement about the size of a PV system or the guaranteed heat yield.

Which devices are in this selection?
Listed are AC ELWA 2, AC•THOR, AC•THOR 9s, SOL•THOR, ELWA, HEA•THOR IoT, screw-in radiators and my-PV WiFi Meter. The overview follows the eight hardware families of the current official product overview. HEA•THOR IoT and screw-in radiators each contain two performance variants.
How do AC and DC solutions differ?
AC devices use alternating current of an existing electrical system and can use PV surplus. DC devices receive energy directly from a suitable PV generator. The connection structure and the necessary regulation differ. A directly connected PV generator is not a freely exchangeable connection to a battery storage.
Which components are needed additionally?
AC•THOR, AC•THOR 9s and SOL•THOR require a suitable separate heat generator. With AC ELWA 2, ELWA and HEA•THOR IoT, the heating rod is integrated. A suitable measurement or supported energy management must be available for PV surplus control. The WiFi meter detects energy flows; it does not generate heat itself.
What should be considered for original data sheets?
Each product has a German original data sheet with file size and documented status. Different revision data are not standardized: For example, the ELWA website mentions IP21, the linked data sheet IP20. Such differences stand on the product and must be clarified before planning.
Which details help with the request?
Name the model or article number, the desired quantity, PV system and inverter, as well as the type of memory, thread and available installation space. With dynamic electricity tariffs, the planned tariff and the desired control help. The product action takes over the selected execution in the central form.
What can I find under "Product Archive"?
There are AC ELWA-E and the former my-PV Power Meter with their original data sheets. AC ELWA-E is the predecessor of AC ELWA 2. Manufacturer's manual The Power Meter 2022 was replaced by the WiFi Meter. The older devices are listed separately from the current range for research into existing equipment. In case of an archive request we take over the exact device type; suitable replacement solutions we clarify personally.
