Austrian specialist in photovoltaic hot water and heating systems, enabling homeowners to maximize solar self-consumption through intelligent power management.
wanga-PV GmbH is a pioneering technology company based in Neuzeug, Austria, dedicated to the concept of "hot water and heating with photovoltaics." Since its founding in 2011, the company has focused on developing electronic photovoltaic power managers that allow users to utilize excess solar energy directly for heating purposes.
Their flagship products, such as the AC•THOR, AC ELWA-E,ndi SOL•THOR, act as intelligent links between photovoltaic systems and heat generators like electric boilers and heating mats. By prioritizing the direct use of solar power for heat generation, my-PV solutions significantly increase the self-consumption rate of PV systems, reduce grid feed-in, and lower operating costs. Their devices support various communication protocols like Modbus RTU and TCP, ensuring seamless integration with a wide range of inverters, battery storage systems, and smart home controllers.

The AC•THOR communicates with compatible inverters via Modbus RTU or TCP. For Modbus RTU, a shielded twisted-pair cable (e.g., CAT cable) is required, along with a 120 Ohm terminating resistor.
Yes, by registering your device on the my-PV Cloud (live.my-pv.com), you can access settings and view operating data from outside your local network.
The SOL•THOR is a photovoltaic power manager designed to operate resistive loads such as electric heating elements, boilers, or infrared panels using excess PV power, without feeding electricity into the grid.
No, the standard AC ELWA-E does not support Modbus RTU (RS485). The AC ELWA 2 or specific Modbus interfaces are required for that communication protocol.
