◼Charge Controller Safety
⚫ NEVER connect the solar panel array to the controller without a battery. Battery must
be connected first.
⚫ Ensure input voltage does not exceed 160 VDC to prevent permanent damage. Use
the Open Circuit Voltage (Voc) to make sure the voltage does not exceed this value
when connecting panels together.
◼Battery Safety
⚫ Use only sealed lead-acid, flooded, gel or lithium batteries which must be deep cycle.
⚫ Explosive battery gases may be present while charging. Be certain there is enough
ventilation to release the gases.
⚫ Be careful when working with large lead acid batteries. Wear eye protection and have
fresh water available in case there is contact with the battery acid.
⚫ Carefully read battery manuals before operation.

Connect battery terminals to the charge controller BEFORE connecting the solar panel(s) to
the charge controller. NEVER connect solar panels to charge controller until the battery is
connected.
Do NOT connect any inverters or battery charger into the load terminal of the charge
controller.
Once equalization is active in the battery charging, it will not exit this stage unless there is
adequate charging current from the solar panel. There should be NO load on the batteries
when in equalization charging stage.
⚫ Do NOT let the positive (+) and negative (-) terminals of the battery touch each other.
Recycle battery when it is replaced.
⚫ Over-charging and excessive gas precipitation may damage the battery plates and
activate material shedding on them. Too high of an equalizing charge or too long of
one may cause damage. Please carefully review the specific requirements of the
battery used in the system.
⚫ Equalization is carried out only for non-sealed / vented/ flooded / wet cell lead acid
batteries.
⚫ Do NOT equalize VRLA type AGM / Gel / Lithium cell batteries UNLESS permitted by

3rd step: connect loads
Connect the load cable to the correct polarity of the right pair of terminals on the solar
charge controller(with the lamp symbol).to avoid any voltage on the wires ,please connect
the wire to the load before connect to the controller.
4th step :Final worked
Tight all cables connected to the controller and remove all the debris around the
controller(leaving a space of approx. 5.91 in)
Notes:
When the reading data of PV or battery is constantly changing ,don’t worry about it , the
controller is finding MPP point,it’s caused by your PV input power or voltage isn’t
enough ,please contact us soon .our technological team will assist you.
◼Air circuit Breaker installation
We strongly recommend connecting a fuse directly to the battery to protect any short
circuit at the battery wiring. Solar PV modules create current whenever light strikes them.
The current created varies with the light intensity, but even in the case of low levels of
light, full voltage is given by the modules. So, protect the solar modules from incident
light during installation. Never touch uninsulated cable ends, use only insulated tools, and
make sure that the wire diameter is in accordance with the expected currents of the solar
charge controller. Connections must always be made in the sequence described below.

It’s better to connect two wires to two PV+ and another two wires to two PV-. For BAT+
and BAT-, it’s same way to connect wires.
1. Install air circuit breaker between controller and batteries. Turn off the circuit breaker,
then connect batteries to controller with correct polarity.
2. Install air circuit breaker between controller and PV modules. Turn off the circuit
breaker, and ensure the PV polarity correct, then connect wires between PV modules
and controller.
3. Turn on the air circuit breaker between controller and batteries.
4. Turn on the air circuit breaker between controller and PV modules.
5. The controller goes into the self-test mode. Its LCD displays the parameters if all is
correct. And RUN lamp (under the fan inside of casing) will flash every one second. If
the controller is no response, please read full manual again for reinstalling or contact us
for help.

Manual Setting
Reminder: The controller will work fine under default setting except lithium battery.
Caution! All steps must be carried out when the PV modules are
disconnected to controller.
Step 1: D00
Press the button PRG, then LCD displays D00. This is setting for load working time
(Default is 24-hour). Press ENT until numbers flash, then press UP/DOWN to set up time
that you want, long-press ENT to confirm it. This output voltage is same as battery. The
load is only for small DC loads less 5A current. If no load, just leave it.
Step 2: D01
Press the button UP, LCD shows 13.8. This is default value of floating charging. Press
ENT until numbers flash, then press UP/DOWN to set up voltage that you want, long-
press ENT to confirm it.
Caution! This value is for one 12V battery. If there are many batteries in
series, the controller will multiply them in proportion automatically and the LCD
only displays the voltage of one battery (For example, if your battery is 4x12V, and
if you set the voltage at 14.1, the charge voltage will be 4x14. 1 automatically, but
the LCD only displays 14.1).
Step 3: D02
Continue to press the button UP, LCD shows 14.5. This is highest absorption charging
voltage for battery. Press ENT until numbers flash, then press UP/DOWN to set up
voltage that you want, long-press ENT to confirm it.
Caution! This value is for one 12V battery. If there are many batteries in

series, the controller will multiply them in proportion automatically and the LCD
only displays the voltage of one battery.
Step 4: D03
Continue to press the button UP, LCD shows 10.0. This is protection value of battery
discharge. Press ENT until numbers flash, then press UP/DOWN to set up voltage that
you want, long-press ENT to confirm it.
It means it’s protected when 12V battery is less 10. 0V and there is no output power from
OU+ and OU-.
Step 5: D04
Continue to press the button UP, LCD shows 00.00 is default for acid batteries.
If it’s for lithium battery, please press ENT until numbers flash, then press UP/DOWN
to choose 01, long-press ENT to confirm it. Step 2 (D01) is no useful when you choose 01
for lithium battery. And the voltage set in step 3 (D02) will be highest charging voltage for
lithium battery.
Press ESC to exit the setting menu.
