| Energy purchase control method |
Available options:
- No limit
- Purchase energy with limited power
|
| Power limit for energy purchase |
When Purchase energy with limited power is selected, input a value in Power limit for energy purchase, which is generally based on the breaker capacity on the grid connection point. An exceedingly high value will cause overcurrent tripping, while an exceedingly low value will impact the startup of controllable loads, including the chargers. |
| Feed-in control method |
Set one of the following feed-in power control methods and the corresponding values according to the requirements of the local grid company to prevent the system from feeding back more power than the settings.
- Total active power unlimited
- Total active power feed-in limit
- Per-phase active power unlimited
- Per-phase active power feed-in limit
Note:
- Per-phase active power unlimited and Per-phase active power feed-in limit are available only when the inverter supports power feed-in per phase.
- When the options Per-phase active power unlimited and Per-phase active power feed-in limit are selected, the Peaking shaving mode under the Self-consumption energy management mode is disabled. If the Peaking shaving mode is previously on, when you apply the settings, the mode is automatically turned off.

| Feed-in power limit value/ratio |
This option is available when Feed-in control method is set to Total active power feed-in limit. You can switch the unit between kW and % to define the power limit value or ratio.
- When defining the feed-in power limit ratio, set Feed-in power limit ratio calculation basis to Nominal power or Installed PV power. When the latter is selected, specify Total installed power of modules.
|
| Phase A/B/C feed-in power limit value/ratio |
When Feed-in control method is set to Per-phase active power feed-in limit, specify the feed-in power limit for each phase. You can switch the unit between kW and % to define the power limit value or ratio. |
| Third-party power generation systems |
When you select On, specify Rated power of third-party power generation system. Note: If a third-party inverter is connected to the system, you can define the value based on the rated power of the inverter. |
| Ultra-fast grid dispatch mode |
Enabling this mode allows faster active power regulation for the system. It is recommended to enable it in scenarios with reverse power protection or zero export control. |
