8.LVD, LVR, Threshold, Dimming
!
1. Day/Night threshold voltage should be set around
0.1 times of open circuit voltage.
2.Day/Night threshold voltage of load disconnect is 0.3V
higher than the setting data, means the load will
disconnect when the solar voltage at 1.3~3.3V.
3.The controller has an automatic day/night threshold
adjustment function. If the lowest voltage of solar array is
higher than the setting day/night threshold, the load has
no output in first night, 24 hours later the controller can
automatically adjust the day/night threshold to meet the
requirements of lighting at night.

will restore only when the battery being recharged to the
recovery voltage.
2.LVR should be higher than LVD at least 0.2V.

8.3 Day/Night Threshold, Day/Night Delay
The controller recognizes day and night based on the
solar array open circuit voltage. This day/night threshold
can be modified according to local light conditions and
the solar array used.
Day/Night threshold setting range: 1.0~3.0V.
In the evening, when the solar array open circuit voltage
reaches the setting day/night threshold, you can adjust
the day/night delay time to make the load turn on a little
later.
Day/Night delay time setting range: 0~30min.
8.4 Auto Dimming
The "Dim Auto" item of SU/SG32 set "Dim V"
and "Dim %" at the same time, press the "Send" key to set
up the controller. when the battery voltage is lower than
the voltage of "Dim V" , it starts to dimming automatically.
Battery voltage reduces per 0.1V, load current decreased
according to the set of "Dim %", the minimum output
current is 10% of the setting current.
