You are advised to retain the default values of the following parameters. If
needed, choose Settings > Other Parameters and set the parameters as required.
Parameter Name
Description
Tracking load
● Enable (default): Adjusts the inverter
output to ensure that the output is
approximately equal to the load.
● Disabled: Maximizes the inverter output
power. However, the output power is still
affected by parameters such as external
scheduling.
Battery reverse current
protection
● Enable: When reverse battery power is
detected at the grid-connection point (the
battery is supplying power to the grid while
discharging to the loads), a command will
be issued to put the battery in standby
mode to eliminate the reverse power. When
battery discharging is needed, a command
will be issued to enable the battery.
● Disabled (default): When reverse battery
power is detected at the grid-connection
point, the reverse power is eliminated by
reducing the battery power output. The
battery standby command is not issued.
Maximum grid power during
battery discharge
Control the maximum target grid power when
the grid-connection point has zero power.
Adjustment deadband
Allowed fluctuation of the target grid power
for the grid-connection point
Fully fed to grid
●
The SmartLogger directly delivers the external scheduling power limit.
●
This mode maximizes the feed-in power. When the generated PV energy in
the daytime is greater than the maximum output capability of the inverter,
the batteries are charged to store energy. When the PV energy is less than the
maximum output capability of the inverter, batteries discharge to maximize
the energy fed to the grid.
TOU
●
This mode applies to scenarios where the price difference between peak and
off-peak hours is large.
●
You can manually set the charge and discharge time segments to lower the
electricity cost. You need to enable Fed to grid in Battery control page.
When the electricity price is low at night, the power grid charges the
batteries. When the electricity price is high, the batteries discharge to supply
power to the loads.
