8 SmartLogger Web-based Deployment
Description
– This mode applies to areas where the
electricity price is high, or areas where the
FIT subsidy is low or unavailable.
– Excess PV energy is stored in batteries. When
PV power is insufficient or no PV power is
generated at night, batteries discharge to
supply power to the loads, improving the
self-consumption rate of the PV system and
the self-sufficiency rate of energy, and
reducing electricity costs.
– The SmartLogger performs battery
scheduling based on the external scheduling
power limit and the preceding policies.
– 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 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.
– Click Add to set the charge/discharge time. 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 battery
scheduling based on the external scheduling
power limit and the preceding policies.
