Table 10-4 Battery control working modes
Working Mode Mode Description
No control The SmartLogger directly delivers the external scheduling
power limit. No other power scheduling control is
performed. The power is automatically controlled by the
device.
Maximum self-
consumption
– This mode applies to areas where the electricity price
is high, or areas where the FIT subsidy is low or
unavailable. This mode is recommended when the PV
+ESS system generates sucient PV energy for loads
and uses the surplus PV energy to charge the ESS (if
the PV energy is insucient to charge loads, the TOU
mode is recommended).
– PV energy is preferentially supplied to loads, and then
the surplus PV energy is charged to the ESS. If the ESS
is fully charged or is being charged at full power, the
surplus PV energy is fed to the grid. When PV energy
is insucient or no PV energy can be generated at
night, the ESS discharges energy to loads. This
improves the self-consumption rate and energy self-
suciency rate, and reduces electricity costs. The grid
cannot charge the ESS.
– The SmartLogger performs ESS scheduling based on
the external scheduling power limit and the preceding
policies.
Fully fed to
grid
– This mode applies only to distributed scenarios.
– This mode maximizes the PV energy fed to the grid.
When the generated PV energy in the daytime is
greater than the maximum output capability of the
inverter, the surplus energy is used to charge the ESS.
When the generated PV energy is less than the
maximum output capability of the inverter, the ESS
discharges energy to the inverter to maximize the
energy fed from the inverter to the grid. The grid
cannot charge the ESS.
– The SmartLogger directly delivers the external
scheduling power limit.
NOTE
If the CMU is connected, the Fully fed to grid working mode is
not displayed.
