How can I use a smart home app to increase the self-consumption of a PV system with a Sunny Home Manager?
(jh) With its energy management, the Sunny Home Manager contributes significantly to increasing self-consumption and the self-sufficiency quota. The level of the increase depends on the design of the various system components. In particular, the use of battery storage systems plays a signficant role.
Control of the heat pump for hot water and/or space heating via Sunny Home Manager brings about a significant increase in energy consumption as households typically use almost 80% of their energy for heating. With PV systems in the range of 5 – 10 kWp, the heat pump can consume almost the entire locally generated PV energy in an optimal situation. The Sunny Home Manager ensures that the heat pump always runs when PV energy is available. By control of special heat pump modes for thermal storage, (overheating of the hot-water tank), PV energy can also be useful when the current heating requirement can be covered by the PV energy.
