Prioritizing Loads

In the case of loads that can be operated flexibly in terms of time, you can specify a sequence that the Sunny Home Manager will use to schedule these loads in its energy management. This prioritization can save you energy costs.

The prioritization will only be considered for the following loads:

• Loads connected to switching devices for which you have set time periods of type Load can be switched on.

• Batteries, if Prioritized battery charging is enabled in the SMA Smart Home settings of the Sunny Home Manager ( > Setting up Forecast-Based Battery Charging).

• Smart appliances with optional energy absorption. You will have already set the priority of these devices when adding them to your Sunny Home Manager system via the configuration wizard.

Effects of prioritization:

• If there are several loads with CAN time periods, the lowest-cost energy will be allocated to the load which you have given the highest priority using the slider.

• If there is not enough low-cost PV energy for all loads with CAN time periods, lower-priority loads may not be switched on at all. For this reason, the priority of appliances with low power, such as washing machines and dishwashers, should be lower than the priority of charging devices such as the SMA eCharger, for example.

• Basically, the Sunny Home Manager schedules optional loads only if it can ensure that the planning target is met. If the slider is set to 100% PV generation, it is possible that optional loads cannot be scheduled for use on cloudy days because minimum grid-supplied power cannot be excluded.

In the case of the time period type Load must be switched on, the priority of the load does not have any effect, as the load is switched on in any event, possibly also with grid-supplied power.
