☑ If you select Proportion of the PV energy, you must use light bulb slider to set the minimum proportion of
PV energy that must be present so that SunnyHomeManager will switch on the load during the configured
time period.
For example, if you set the slider to 50%, the device (e.g., a heating element) will be turned on only when
there is enough PV energy to meet 50% of the energy demand.
The percentages for each energy type are displayed to the right of the slider.
☑ If you select Maximum permitted energy costs, you must use the light bulb slider to set the maximum
energy costs at which SunnyHomeManager will switch on the load during the configured time period.
For example, if you set the slider to 0Euro/kWh, the device will be switched on only when there is enough
surplus PV energy or when there is more PV energy available than can be fed into the utility grid.
The costs are displayed in Eur/kWh to the right of the slider.
