Grid limits
Note
The grid system, current and power limits are requested during the initial setup. You can later change them from the menu "Settings" in the commissioning interface.
-
Enter the nominal current of the main circuit breaker of the electrical installation.
-
Choose the appropriate grid system under "Grid system." You have the choice of:
- Single-phase 230V
- Three-phase wye 230V line-neutral / 400V line-line
- Three-phase delta 230V line-line
-
Under "Allowed grid import power", enter the maximum power that may be taken from the grid.
This corresponds to an import limit. -
Under "Allowed grid export power" enter the maximum power that may be fed back to the grid.
This corresponds to an export limit. -
You can optionally enter a safety margin, under "Allowed grid export power safety margin" if desired.
Note
"Three-phase delta 230V line-line" occurs only in certain geographical areas.
Allowed Grid Export Power Safety Margin (kW)
By default, this is set to 0.0 if you’re working in the cloud—meaning no extra buffer is added.
If you’re running outside of the cloud, a minimum safety margin of 1.5% is required.
