my-PV - Since 2011, we have been developing innovative home technology solutions powered by solar power. We get more out of your photovoltaic system than just electricity – for people and the environment. Sustainability and low costs are no contradiction.
Increase your own consumption - With the ACTHOR you can get more out of the photovoltaic power. Use excess photovoltaic power itself for heating purposes instead of feeding it in unprofitable. Save operating costs by hot water with the sun.
Continuously adjustable - The ACTHOR regulates a heating rod continuously from 0 - 3 kW, adjusted to the second depending on the excess from the photovoltaic system. For the ideal use of solar power for heating purposes.
Combinable - The compact PV power manager is compatible with over 70 manufacturers of inverters, battery systems, heat pumps and smart homes. For lived system openness, so that retrofitting to photovoltaic heat is easily possible.
ACTHOR - The ACTHOR is a 0 - 3 kW continuously controlled photovoltaic power manager that controls electrical heat sources such as hot water and heating. It ensures up to 85% PV self-consumption, even without battery storage.
