Set between 1-40A. For example

10.0 means the charge

Setting between 0-23 hour and 0-59 minute. For example,
set as 08:00, it means the system will discharge battery
power to the grid (feed to grid) from 08:00 in 1

st

Set between 0-11 hour and 0-59 minute. For example, the
setting is 03:20, it means the 1

hour and 20 minutes (if the timing mode is started, but
don’t want it discharge,change the discharge period to

Mini. SOC of 1

st

discharge period

50%

Set between 20%-100%;for example,set as 50% it means
the system will stop discharge battery power to the grid
(feed to grid) once the battery SOC reaches to 50% in the
1

st

discharge period. The SOC will be compared with the

discharge time, whichever arrives first and it stops first. For
example:
SOC is set as 50%, while the discharging(feeding to grid)
time is set as 10 minutes. When battery SOC discharges to
60%, but the discharge time already reach to 10 minutes,it
will stop discharging(feeding to grid) also.
Another example:
SOC is set as 50% and the discharging time is set as 10
hours. If the battery is discharged to 50% less than 10
hours,the system will also stop discharging to grid before
reach the set time.
(This discharging/feeding to grid has nothing to do with
solar power.For solar charger,it will be automatically
charged as long as there is solar power).

discharging here refers to battery power feeds to grid.For
example,if it set as 20A, the battery power feeds to grid is:
26V*20A=520).
