Load power supply priority: PV power > ESS discharging > Grid
This mode applies to scenarios where the price difference is large between
peak and off-peak hours. When the electricity price is low during off-peak
hours, the grid supplies power to charge the ESS. When the electricity price is
high during peak hours, the ESS discharges to supply power to household
loads.
In some countries, the grid is not allowed to charge the ESS. In such case, this
mode cannot be used.
In this mode, at least one charge time segment or one discharge time
segment is required. During the charge time segment, the grid is allowed to
charge the ESS. During the discharge time segment, the ESS can supply power
to the loads. In other time segments that are not set, the ESS does not
discharge, and the PV system and grid supply power to the loads. (In on/off-
grid mode, if the grid fails, the ESS can discharge at any time.)
Set the working mode to TOU. For details, see
