5.5、Time-slot charging/discharging function
The SEI-SP series is equipped with a time-slot charging and discharging function, which allows users to set
different charging and discharging periods according to the local peak and valley tariffs, so that the utility power
and PV energy can be used rationally.
When mains electricity is expensive, the battery inverter is used to carry the load; when the mains electricity is
cheap, the mains electricity is used to carry the load and charge, which can help customers to save electricity
costs to the greatest extent.
The user can turn on/off the time-slot charging/discharging function in setup menu parameter 46 and 53.and
set charging and discharging slot in parameter . Below are examples for users to understand the function.
Time-slot Utility Charging/Carrying Function Time-slot Battery Disacharging Function
With 3 definable periods, the user can freely
set the mains charging/carrying time within
the range of 00:00 to 23:59. During the time
period set by the user, if PV energy is
available, PV energy will be used first, and if
PV energy is not available or insufficient,
utility energy will be used as a supplement.
With 3 definable time periods, users can freely set
the battery discharge time within the range of 00:00
to 23:59. During the time set by the user, the inverter will
give priority to the battery inverter to
carry the load, and if the battery power is insufficient,
the inverter will automatically switch to mains power to
ensure stable operation of the load
