Installation
Instruction Notes
1st step: Connect the batteries
Connect the battery connection cable with the correct polarity to the middle pair of terminals on the solar charge controller(with the battery symbol).if the system is 12V, please make sure your battery voltage more than 12V, then the controller can boot up.
2nd step: Connect the solar panel
Ensure that the pv modules is protected from incident light. ensure that the solar panel doesn’t exceed the maximum permissible input current. Connect the pv modules connection cable to the correct polarity of the left pair of terminals on the solar charge controller(with the pv modules symbol).
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 connecting 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.
Air Circuit Breaker and Wires Requirement
| Models | Copper wires | Air circuit breakers |
| MPPT-60A | 6mm²x2PCS | 100A |
Reminder
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.
- Install air circuit breaker between controller and batteries. Turn off the circuit breaker, then connect batteries to the controller with the correct polarity.
- Install air circuit breaker between controller and PV modules. Turn off the circuit breaker, and ensure the PV polarity is correct, then connect wires between PV modules and controller.
- Turn on the air circuit breaker between the controller and batteries.
- Turn on the air circuit breaker between the controller and PV modules.
- 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 respond, please read full manual again for reinstalling or contact us for help.

Manual Setting
Reminder: The controller will work fine under the default setting except for lithium battery.
Caution! All steps must be carried out when the PV modules are disconnected from the controller.
Step 1: D00
Press the button PRG, then LCD displays D00. This is setting for load working time (Default is 24 hours). 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 the same as the 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, and 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 4×14. 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 the protection value of battery discharge. Press ENT until numbers flash, then press UP/DOWN to set up the voltage that you want, and 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 the default for acid batteries. If it’s for lithium battery, please press ENT until numbers flash, then press UP/DOWN to choose 01, and long-press ENT to confirm it. Step 2 (D01) is no use when you choose 01 for a lithium battery. And the voltage set in step 3 (D02) will be the highest charging voltage for a lithium battery.
