7.21 Setting the Search Mode
Search mode makes it possible to save energy.
At regular intervals, the off-grid inverter checks whether loads are connected to the off-grid system.
If the off-grid inverter does not detect any loads, it switches to energy-saving mode. As soon as a load
is connected, the off-grid inverter exits energy-saving mode and switches to inverter operation.
Requirement:
☐ For single-phase parallel systems, sleep mode must be activated.
1. Switch to installer mode (see Section 7.5).
2. Select the 250.31 SearchMod parameter and set it to the desired value:
3. Switch to expert mode (see Section 7.6) to change the sensitivity of the detection of loads or to
control the search mode in a time-controlled manner.
4. To change the sensitivity, select the 250.32 SearchModSns parameter and set it to the desired
value:
5. To operate search mode in a time-controlled manner, change the start time and stop time:
• Select the 250.33 SearchModStr parameter and set it to the start time.
• Select the 250.34 SearchModStp parameter and set it to the stop time.
7.22 Setting the Silent Mode
Silent mode makes it possible to save energy in backup systems.
Detection of loads in a three-phase system
In a three-phase system, each off-grid inverter automatically activates energy-saving mode
independently for each line conductor. In a three-phase system, the off-grid inverter does not
identify loads as loads when they are connected using delta connections.
Value Explanation
Disable Search mode is deactivated.
Enable Search mode is activated with no interruptions.
Timed Search mode is activated only in the set time interval.
Value Explanation
Very High Highest sensitivity
High High sensitivity, P < 15 W
Middle Middle sensitivity, P < 20 W
Low Low sensitivity, P < 30 W
Very Low Lowest sensitivity, P < 50 W
