2.Safety instructions and waiver of liability
2.1 Safety
①The solar charge controller may only be used in PV systems
in accordance with this user manual and the specifications of
other modules manufacturers. No energy source other than a
solar generator may be connected to the solar charge
controller.
②Batteries store a large amount of energy, never short circuit a
battery under all circumstances. We strongly recommend
connecting a fuse directly to the battery to protect any short
circuit at the battery wiring.
2.2
③Batteries can produce flammable gases. Avoid making sparks,
using fire or any naked flame. Make sure that the battery 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.

4.Installation
The following diagrams provide an overview of the connections
and the proper order.
Page 1 of 5 pages
1.Follow the chart, connect the load (positive pole and
negative pole) with the corresponding brown and blue
cables firstly, then seal them with tape.
2.Connect battery positive and negative pole to the
corresponding red and black cables, the load will be on after
8s;
3.Connect the panel positive pole and negative pole to the
corresponding red and black(or green) cables, the load will
be off after 4s, and the controller begins to charge.
4.Confirm the LED display status: If the red LED is off and the
green LED flashes or constantly light, it is normal; else it
means fault, please refer to the 9.2 Faults and Alarms to
identify the reason.
Make sure the length between battery and controller is as
short as possible.
Recommended minimum wire size: 2.5mm²;
For easy installation and testing, in the first 30 minutes,
charging and discharging conversion requires only 8s. After 30
minutes, charging and discharging conversion takes time of 5
minutes.

5.1 Test function
Press the“Test”key of S-Unit, the controller will turn
on load for 30s. During daytime, the testing function can
help users to verify correct installation or for system
trouble shooting. 30s later the load will automatically
turn off.
The relationship between “Test”key press times in
the 30s and the output power of the controller is shown
in the following table:

4.2 Transportation mode
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.
4.2.3 Exit the transportation mode
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.
If the controller enters transport mode, the red LED
will slow flash(0.2s on/5s off ) ，the green and yellow led
will be off and the remote control displays "Open CP".
When the load is properly connected, press the test key
or connect the solar more than 1s during daytime , the
transport mode will terminate and the controller will
work normally.
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.

8.LVD, LVR, Threshold, Dimming
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.
8.1Low Voltage Disconnect(LVD)
Low voltage disconnect setting range: 8.0~15.0V.
!
If the controller goes into low voltage disconnect, it will
restore only when the battery being recharged to the recovery
voltage.
Sunset
Dusk
Sunrise
Dawn
3.0~8.0V 4.0~9.0V
!
1. Day/Night threshold voltage of load disconnect is 1V
higher than the setting data, means the load will disconnect
when the solar voltage at 4.0~9.0V.
2.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.
8.2Low Voltage Reconnect(LVR)
Low voltage reconnect setting range: 8.6~16.0V.
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 S-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 0.1V, load current decreased according to the set of
"Dim %", the minimum output current is 10% of the setting
current.
!
If the controller is set to “Dim” or “Auto Dim”, the
minimum output power can be as low as 50mA.
Smart series controller with advanced street light control
function. The modes of lighting can be based on customer
needs.

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.
