2.1 Safety
①The solar charge controller may only be used in PV
systems in accordance with this user manual and the
specs of other module manufacturers. No energy source
other than solar gen. may be connected to the solar
charge controller.
②Batteries store a large amount of energy, never short
circuit a bat. under all circumstances. We strongly
recommend connecting a fuse directly to the battery to
protect any short circuit at the bat. wiring.
2.2
③Batteries can produce flammable gases. Avoid making
sparks, fire or any naked flame. Make sure that the bat.
room is ventilated.
④Avoid touching or short circuiting wires or terminals.
Be aware that the voltages on special terminals or wires
can be as much as twice the battery voltage. Use isolated
tools, stand on dry ground, and keep your hands dry.
⑤Keep children away from batteries and the charge
controller.
Liability Exclusion
The manufacturer shall not be liable for damages,
especially on the battery, caused by use other than as
intended or as mentioned in this manual or if the
recommendations of the battery manufacturer are
neglected. The manufacturer shall not be liable if there
has been service or repair carried out by any
unauthorized person, unusual use, wrong installation, or
bad system design.

5.1 Test function
Press the "Test" key of S/SG-Unit, the controller will turn on
load for 10s. During daytime, the testing function can help
users to verify correct installation or for system trouble
shooting. 10s later the load will automatically turn off.
5.2 Read the running status
Press the "Status" key of the S/SG-Unit to read the running
status of the controller.
The following diagrams provide an overview of the
connections and the proper order
4.Installation
Make sure the wire length between battery and
controller is as short as possible.
Recommended minimum wire size:
8/10A: 2.5 mm²; 15/20A: 4 mm².

1. As the chart, connect the load with the corresponding
brown(positive) and blue(negative) cables firstly, then
seal them with tape.
2. Connect battery with the corresponding red(positive)
and black(negative)c ables. Load will be on after 5s.
3. Connect panel with the corresponding red(positive)
and black/green( negative) cables, the load will be off
after 5s, and the controller begins charging.
4. Refer to 9.1 LED indications and Faults & Alarms to
confirm the LED display status.
4.2 Transportation mode(Lithium)
The controller is generally integrated with the lithium
battery in the lithium battery pack for transport, if the
controller works normal during transport, it will waste of
energy and increase the transport risk. If the controller is
set to transport mode, the load has no output, then the
power consumption is reduced by about 60%, to avoid
lithium battery voltage too low.
4.2.1 Open circuit protection
If the controller is only connected with the battery, but
not connected with solar and load, the controller will
enter transportation mode after 5 minutes.
4.2.2 Press the "Test" key in transport mode
Press the "Back" and "Backlight" key at the same time
more than 3s, the remote controller will work in transport
mode.
Press the "Test" key in the transport mode, the remote
controller displays "Transport OK" and will beep a long
sound, the controller enters into transport mode.

6.Starting up the controller
6.1 Self Test
As soon as the controller is connected to battery, it starts
self test. Then the display changes to normal operation.
6.2 Battery Type
The controller applies to Lithium, AGM, Liquid and Gel
battery, the factory default setting is suitable for Lithium
battery.
When the controller is set to Lithium battery, the
charging target voltage and charging recovery voltage
can be set according to customer requirements.
The controller adjusts itself automatically to 12V or 24V
system voltage when it is set to Gel, Liquid or AGM
battery. If the battery voltage on start-up is 0V-15.5V
then the controller infers a 12V system.
If the battery voltage is 20V-30V the controller infers a
24V system.If the battery voltage is not within the normal
operating rang(ca.0 to 15.5V or ca.20 to 30V) at start-up,
please refer to 9.2 Faults & Alarms.
6.3 0℃ Charging Protection
"" " "
""
""
" "
"0℃ Chg" can be set to Yes", "Slow or No . When the
controller detects that the ambient temperature is higher
than 0℃, the charging function is normal. when the
ambient temperature is low than 0℃, if the "0℃ Chg" is
set to Yes , the charging function is normal, else if the
"0℃ Chg" is set to slow , the max charging current is
20% of the rated current, else if the "0℃ Chg" is set to
No , the controller does not charge the battery.
The user can select the appropriate charging method.

The controller works as follows：
After the arrival of the evening the first time the load is
lit for 1 hour (full power 100%), the second time the load
is lit for 2 hours (power 80%), the third time load light for
3 hours (when people is near the lamp then the load is
60% light, when people is away from the lamp the load is
60% * 10% light), and then the controller according to
the actual night time automatically calculate the length
of the fourth paragraph (when people is near the lamp
then the load is 40% light, when people is away from the
lamp the load is 40% * 10% light), the fifth time load
light 2 hours (full power 100%).
For controllers with infrared sensing function( R series), if
work mode is set to Five-stage Night Mode or T0T mode ,
"DelayOff and Dim NP work in Time3 and Time4 .
"DelayOff" setting range: 10~150s.

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.

8.3 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.
