Time Plan

The Time Plan mode is mainly used for electricity trading scenarios. Users can set the time windows and power for battery charging/discharging according to the on- and off-peak electricity prices to maximize the economic benefits.

It is recommended to schedule battery discharge during on-peak hours (electricity prices are higher) and charge during off-peak hours (electricity prices are lower).

Function Logic

  • Discharge Period: The battery discharges at the predefined discharging power within the set time period until it is fully discharged.
  • Charge Period: The battery charges at the predefined charging power within the set time period until it is fully charged.

Procedure

  1. Navigate to the Energy Management page and select the Time Plan mode.
  2. Set the desired month span. You can set different time windows based on seasonal energy demand patterns.

  3. Select the days on which the battery charging/discharging plan applies.

    You can apply the charging/discharging plan to all days, or set different charging/discharging plans for weekdays and weekends. The work plan applies to all days by default.
    • Every Day: The set charging/discharging plan applies on all days. This option is ideal for scenarios where the daily electricity price is relatively consistent.
    • Weekdays & Weekends: Set different charging/discharging plans for weekdays and weekends.
  4. To add more month spans, click Add to the right of the default month span name.
    Note:

    Before adding a month span, you must first configure the charge and discharge settings for the current month span.

    You can select a month span and click to modify its name or delete it.

  5. Click on a time period in the Discharge or Charge time bar. A new discharging or charging window will be created (1 hour by default). Then, drag the left or right edge of the window to adjust the time range.
    Note:

    The charging and discharging windows cannot overlap.

    The battery will not discharge in a time period with no settings. If the PV output is insufficient to meet the load demand, the system purchases energy from the grid to meet the load demand, and allows the battery to charge from the excess PV energy.

  6. Click a time window that has been added, set the discharging or charging power in Power.

  7. Click Apply Settings.
