4.Starting up the controller
4.1 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.
4.2 System Voltage
The controller applies to Lithium, AGM, Liquid and Gel
battery, the factory default setting is suitable for Gel
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.
If the battery voltage on start-up is 10V-15V , the controller
infers a 12V system when the controller is set to Gel, Liquid
or AGM battery. If the battery voltage is not within the
normal operating rang(ca.10 to 15V) at start-up, please
refer to 8.2 Faults & Alarms.

6.3 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.
1. Lithium Battery
LVD range: 9.0~15.0V(default: 9.0V).
2. Gel, Liquid and AGM Battery
The low voltage protection of the controller can be
divided into two types:
batter y voltage control and capacity control.
a. Batter y voltage control
Low voltage disconnect setting range: 10.8~11.8V
(default: 11.2V).
6.BlueTooth
5.App installation
The controller has Bluetooth communication function,
the Bluetooth module of the controller can be connected
to mobile phone after installing APP.
For detailed operation, please read the "Bluetooth APP
instructions " . App on mobile phone can view the real-
time working state of the controller and set parameters,
including device and battery parameters.
6.1 Charging Voltage (Liquid/ GEL/AGM)
When choosing Liquid, GEL or AGM for battery type, the
parameters of boost, equalization and float charging
voltage can be set by mobile phone APP. The range of
parameters is as follows.
The following voltage parameters are 25℃/12V system
parameters.

6.2 Charging Voltage Parameters(Lithium)
When choosing lithium battery type, the overcharge
protection and overcharge recovery voltage of lithium
battery can be set by mobile phone APP.
Overcharge protection voltage(CVT): 10.0-17.0V
Overcharge recovery voltage(CVR): 9.2-16.8V.
The required accuracy of PCM shall be at least
0.2V. If the deviation is higher than 0.2V, the
manufacturer will assume no liability for any
system malfunction caused by this.

7. Load Modes
6.6 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: 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 delay).
Day/Night delay time setting range: 0~30min.
!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.
!The controller will automatically adjust the day/night
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.

Dusk
Sunrise
Dawn
3.0~8.0V 4.0~9.0V
6.5 0℃ Charging(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.
b. Battery capacity control
Low voltage disconnect setting range: Soc1~Soc5
6.4 Low 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.
1. Lithium Battery
LVR range: 9.6~16.0V.
2. Gel, Liquid and AGM Battery
LVR range: 11.4~12.8V.
The low voltage recovery voltage(LVR) should
be higher than the low voltage disconnect
voltage(LVD) at least 0.6V, if you want to
improve LVD, you should first improve LVR.

Low voltage protection range 7.1 Always on Mode
When the controller is set to always On mode, no matter
the charging or discharging state, the load is always
powered on (except in when in protection state).
7.2 Street Lamp Function
When the load is set to D2D(Dusk to Dawn) or Evening
mode, the Day/Night threshold voltage and the
Day/Night delay time can be set, and the load can be
turned on or off by the test function during the day
charging process.
7.3 Five-stage Mode
Time 1-5 and Dim 1-5 can be set individually to give
variable load power throughout the night.
*If "Time4" is set to "T0T", this mode is T0T mode, the
controller will determine Time4 based on Time5 and
previous data on the time of sunrise.
7.4 Manual Mode
If the load mode is selected "Manual", then you can
switch on and off the load output manually by bluetooth
APP.

10.Safty Instructions and Liability Waiver
10.1 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
shortcircuit
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.
10.2
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.
