Make sure the wire length between battery and controller
is as short as possible.
Recommended Wire size: Load and battery: 4mm²

2.1 Safety
①The solar charge controller may only be used in PV
systems in accordance with this user manual and with solar
panels specifications in line with the requirements of this
controller. No energy source other than solar panels may be
connected to the solar charge controller.
②Batteries store a large amount of energy, never short-
circuit a battery under any circumstances. We strongly
recommend connecting an in-line fuse or circuit-breaker on
the "+" wire between the battery and controller, no more
than 15cm from the battery terminal.
2.2
③Batteries can produce flammable gases. Avoid sparks and
flames near the batteries. Make sure the battery is installed
in a well ventilated area.
④Avoid touching or short circuiting wires or terminals. Be
aware that the voltages on special terminals or wires can be
several times greater than the battery voltage. Use isolated
tools and only perform any work in a dry environment.
⑤Keep children away from batteries and the charge
controller.
Liability Exclusion
The manufacturer shall not be liable for damages to the
controller or battery caused by use other than as instructed
in this manual, or if the battery manufacturer's
recommendations are neglected. The manufacturer shall
not be liable if there has been service or repair carried out
by any unauthorised person, unusual use, incorrect setup,
or bad system design.
Dear Clients,
P it will help
you take full advantage of the controller's features. This manual gives important recommendations for installing, using, and
programming the solar controller. Read this manual in full before installing or connecting the solar controller.
Thanks for selecting the Smart series solar controller. lease take the time to familiarise yourself with this user manual, as
!
LED will slow flash(0.2s on/5s off ) ，the green and
yellow led will be off and the remote control displays
"Open CP".
If the controller enters transport mode, the red
4.2.2 Exit the transportation mode
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.
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 Press the "Test" key
Press the "Back" and "Backlight" key at the same time
more than 3s, the remote controller will work in factory
mode. Press the "Test” key in the factory mode, the
remote controller displays "Transport OK" and will beep
a long sound, the controller enters into transport mode.

6.1 Self Test
As soon as the controller is powered, it starts a self test
routine. After this, the LED display will change to normal
operation.
6.2 System Voltage
SMR25-V3212: The controller is applied to Lithium
rechargeable battery . The charging target voltage and
charging recovery voltage can be set according to
customer requirements.
SMR15-V1212: The controller applies to Lithium, AGM,
Liquid and Gel battery, the factory default setting is
suitable for Lithium battery. It is your responsibility to
check and ensure that these settings are correct for your
battery, otherwise they must be amended.
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 system
voltage when it is set to Gel, Liquid or AGM battery. The
controller infers a 12V system when the battery voltage
on start-up is 10V-15V.If the battery voltage is not within
the normal operating rang(ca.10 to 15V) at start-up,
please refer to 9.2 Faults & Alarms.
6.3 0℃ Charging Protection(Lithium)
"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.

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 low voltage disconnect is triggered, the controller
will restore load connection only when the battery
voltage increases above the LVR voltage.
The controller will output both in the day and night
through set Time 3,4,5 by S-Unit(time 1 and 2 are set to
0H at this time).
If you want to achieve daytime output and night output
at regular time, you can set time 4 to T0T and time 5 to
desired time.
8.LVD, LVR, Threshold
Smart series controller has advanced day/night time
control functions. Can be Progrmmable according to
customer needs.
7.2 Night Mode(Time1,2）
7.3 Day Mode(Time3,4）
7.4 Day + Night Mode(Time3,4,5）
Set time 1 and 2 by the S-Unit to output at night.
When time 1 is set to D2D, which means dusk to dawn
mode, load output will last for the whole night, and the
maximum working time of D2D mode is 18 hours.
Set time 3 and 4 by the S-Unit(set time 1, 2 and 5 to 0h
at the same time) to output during the day.The load will
continue to output until night when time 4 is set to T0T.
The maximum working time of T0T mode is 18 hours.

8.3Day/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/3.0~8.0V
The actual time of turning on can be delayed by up to 30
minutes from the time the threshold was reached
using the Day/Night delay setting (D/N Dly).
Day/Night delay time setting range: 0~30min.

!The controller will automatically adjust the day/
threshold. If the lowest solar voltage is higher than the
day/night threshold. The load will have no output the
first night, then 24 hours later the controller will
automatically adjust the setting to give output the
following night.
