5.5、Time-slot charging/discharging function
The SPI 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 40-45, 47-52. 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 period 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.
