8.LVD, LVR, Threshold, Dimming
8.1 Low Voltage Disconnect (LVD)
When the battery voltage drops below the LVD voltage,
the controller will disconnect the load to prevent deep
discharge of the battery. If this occurs, the battery should
be well charged before resuming use.

8.2Low Voltage Reconnect (LVR)
If the controller goes into low voltage disconnect, it will
restore only when the battery being recharged to the
recovery voltage.
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:
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.

8.4 Auto Dimming
8.4.1 Auto Dimming mode
The "Dim Auto" item of S/SG-Unit is set to "Yes", 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 0.1/0.2V, load
current decreased according to the set of "Dim %", the
minimum output current is 10% of the setting current.
!
minimum output current can be as low as 100mA.
If the controller is set to "Dim" or "Auto Dim", the
8.4.2 365mode（Lithium）
365 mode is based on the battery power (charge power,
discharge power) energy control. If the battery charge
more during the day, then discharge more at night. The
controller can calculate the dimming ratio according to
the charging power and the remaining power of battery,
so as to avoid the load shutdown due to the low battery
voltage.
!
designed to meet the requirements of three rainy days.
When using the 365 mode, the system should be
!
1. Day/Night threshold voltage should be set around
0.22 times of open circuit voltage.
2.Day/Night threshold voltage of load disconnect is 1V
higher than the setting data, means the load will
disconnect when the solar voltage at 4.0~9.0/4.0~21.0V.
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.
