●
Click Add to set the charge and discharge time segments. A maximum of 14
time segments can be set. During the charging period, the power grid charges
the batteries, and during the discharging period, the batteries discharge to
supply power to the loads. In other time segments that are not set, the
batteries do not discharge, and the PV modules and grid supply power to the
loads. (In grid-tied/off-grid mode, if the grid fails, the batteries can discharge
at any time.)
●
In some countries, the grid is not allowed to charge batteries. Therefore, this
mode cannot be used.

The SmartLogger performs energy storage scheduling based on the external
scheduling power limit and the preceding policies.

Description
Preferred use of surplus PV
power
● Charge: When the generated PV energy is
greater than the loads, excess PV energy is
used to charge the batteries. After the
maximum charge power is reached or the
batteries are fully charged, the excess PV
energy is fed to the grid.
● Fed to grid: When the generated PV energy
is greater than the loads, the excess PV
energy is preferentially fed to the grid.
When the maximum output power of the
inverter is reached, the excess energy is
used to charge the batteries. This setting is
applicable to the scenario where the FIT is
higher than the electricity price. Batteries
are used only for power backup.
Maximum power for charging
batteries from grid
Sets the maximum power of the grid during
battery charging.
Start time
● Sets the Charge/Discharge time. A
maximum of 14 time segments can be set.
You can set a cycle by week by clicking the
buttons corresponding to Mon. through Sun.
in the Repeat box. The buttons are blue by
default, indicating selected. After you click
it, the color turns gray.
