Parameter Description
TOU Preferred use
of surplus PV
power
– Charge: When the PV power is greater
than the load power, the surplus PV
energy is used to charge the ESS. After
the maximum charge power is reached
or the ESS is fully charged, the surplus
PV energy is fed to the grid.
– Fed to grid: When the PV power is
greater than the load power, the surplus
PV energy is preferentially fed to the
grid. When the maximum output power
of the device is reached, the surplus
energy is used to charge the ESS. This
setting is applicable to the scenario
where the FIT is higher than the
electricity price and the grid cannot
charge the ESS.
Maximum
power for
charging
batteries from
grid
Set the maximum power at which the grid
charges the batteries.
Active power
threshold of
grid during
battery
discharge
Set the maximum target grid power when
the grid-connection point has zero power.
Adjustment
deadband
Set the allowed uctuation of the target
grid power for the grid-connection point.
Adaptive
adjustment
parameters
[1]
Set the adjustment period and step
parameters for raising the inverter power.
– Enable: The adjustment period and step
set in the SmartLogger are used.
Generally, the adjustment period and
step are calculated based on the number
of devices connected to the port and
device specications.
– Disable: Use this value based on site
requirements.
Adjustment
period
[1]
This parameter is displayed after Adaptive
adjustment parameters is set to Disable.
You can set this parameter based on site
requirements. In this case, battery control is
performed based on the preset period.
