7.19 Changing the Current Limiting Values for the Electricity Grid
Significance of the current limit:
Grid management limits the consumption of line current to the set maximum value.
Advanced grid management:
If the set line current is not sufficient for supplying the loads, grid management requests additional
power from the battery. The off-grid inverter then feeds additional power from the battery into the
stand-alone grid.
1. Switch to installer mode (see Section 7.5).
2. Select the 232.03 GdCurNom parameter and set it to the maximum line current.
7.20 Changing the Sleep Mode
Sleep mode makes it possible to save energy in single-phase parallel off-grid systems.
If the power of the loads does not require the power of all off-grid inverters, the master switches off
one or two slaves. The power thresholds at which the slaves are switched off and on have been
optimised at the factory. You cannot change the power threshold.
1. Switch to installer mode (see Section 7.5).
2. To deactivate sleep mode, select the 250.10 SleepEna parameter and set it to Disable.
3. To activate sleep mode, select the 250.10 SleepEna parameter and set it to Enable.
4. To activate sleep mode in a time-controlled manner, activate overnight shutdown and change
the times:
• Select the 250.10 SleepEna parameter and set it to Enable.
• Select the 250.13 SleepAtNight parameter and set it to Enable.
• Select the 250.14 SlpStrTm parameter and set it to the start time.
• Select the 250.15 SlpStpTm parameter and set it to the stop time.
