Special functions

Automatic timer

The automatic time profile operators independent of the current PV production. Up to 10 periods can

be defined based on the time.

Performance Visualization

The performance visualization profile can be used in connection with the Solar-Log™ Smart Relay Box.

The Relay Box has 8 relays. The relays can be switched on in stages. The value for the activation the

individual relays needs to be defined.

Threshold and Time Control

With this profile, appliances can be controlled based on the configured switching thresholds and also

with optional automatic timer settings. An upper threshold for activation and a lower threshold for

deactivation need to be configured. Additionally, a time period can be defined in which the appliance

is switched on or off if this has not already been done via the threshold control. The minimum duration

the appliance has to be switched on for is defined in the previous duration box. If this duration is not

covered with the threshold control, the appliance is switched on for the entire defined duration.

Generation Information on Thresholds

Five-minute values are generated to balance the fluctuations in PV production (e.g. due to clouds) for

managing appliances. The average value is aligned to the threshold set in the respective logic control.

Generation Information on typical nominal power�

The typical nominal power is the average consumption of appliances that is controlled by the profile.

Appliances, such a laundry dryer, have a short high peak of power consumption and times in which little

power is required. Based on this, it would be problematic to calculate the current power consumption for

power management control. For this reason, the Solar-Log™ calculates with the configured value for typi-

cal nominal power during the entire duration of operation.

Note

When configuring the control logic make sure to allocate profile positions so that the

power supply (for surpluses) is adjusted to the priority of the managed appliances.
