This describes how to install and service MPPT solar charge controller.

1.1 Validity

This manual applies to the whole MPPT Solar Charge Controller 60A models produce by our company:

1.2 Target Group

This manual is intended for the installer and the operator.

1.3 All manuals for the device and installed components must be stored in the immediate vicinity of the charge controller and must be accessible at all times.

1.4 Symbols Used

The following types of safety messages and general information appear in this document:

● Before using the solar charge controller, please read all instructions and cautionary markings on the solar charge controller, and all corresponding sections of this guide.

● Please use components and parts recommended or sold by I-Panda New Energy. Otherwise may result in a risk of fire, electric shock, or injury to person.

● To avoid a risk of fire and electric shock, make sure that existing wiring is in good

condition and that wire is not undersized. Do not operate the solar charge controller with damaged or substandard wiring.

● Do not disassemble the solar charge controller. It contains no user-serviceable parts.

See Warranty for instructions on obtaining service. Attempting to repair the solar charge controller by yourself may result in a risk of electric shock or fire and will make your warranty invalid.

● To reduce the risk of electric shock, authorized service personnel must use insulating tool to operate the device.

● Keep away from flammable, explosive materials to avoid fire disaster.

● The installation place should be away from humid or corrosive substance.

● To reduce the chance of short-circuits, authorized service personnel must use insulated tools when installing or working with this equipment.

3. Unpacking           

3.1 Device parts checking：

If there is any part missing, please contact your dealer.

3.2 Check for Transport Damage

Check the charge controller for visible external damage, such as cracks in the enclosure. Contact your dealer if you find any damage.

3.3 Identifying the Charge Controller

You can identify the charge controller by the type label. The type label is in the enclosure.                                                                                                    

4.1 Operator：technical personnel;

4.2 Selecting the Mounting Location

     L * W * H：270mm*150mm*88mm

4.2.2 Net Weight

     Weight：3kg

4.2.3 Ambient Conditions

• The mounting location and method must be suitable for the weight and dimensions.

• Mount on a solid surface.

• The mounting location must be accessible at all times.

• The charge controller must be easy to remove from the mounting location at any time.

• The ambient temperature should be between -20 °C and +60 °C to guarantee optimal operation.

• Do not expose the charge controller to direct sunlight to avoid power losses due to overheating.

4.2.4 Safety Clearance

Observe the following safety clearance to wall, other devices or objects to ensure sufficient heat dissipation.

5. Connections of the PV power system

5.2.1 PV String

Solar charge controller device can be connected in series into 1-strings PV modules. Please select PV modules with excellent function and reliable quality. Open-circuit voltage of module arrays connected in series should be less than Max. DC input Voltage (150V); operating voltage should be conformed to MPPT voltage range.

Please use PV cable to connect modules to device. From junction box to device,

voltage drop is about 1-2%. So we suggest the solar charge controller install near PV module, in order to save wire and reduce DC loss.

5.2.2 The voltage of  battery system and types

1) This controller could charge for DC 12 V/ 24 V/48V battery system . It would automatic recognition the voltage system :

2) The controller had already been set to charge 4 types battery as following form . If have other need , the charge parameter also could be reset through machine and solar eagle . The details please check the illustrate .

5.2.3 The voltage of DC load system and Max current :

This controller had added DC load output function , the output voltage range based on the type of battery bank system . Like the battery bank voltage is 48V , DC output voltage range will be the range of 48V battery bank working voltage .

1) How to turn DC output turn on/off ?

Please find the DC output control through MPPT or Solar Eagle software . It have 6 way to control it : ON Mode / OFF Mode / Time Control Mode /PV Volt Ctrl / PV&Time Ctrl : Details please check the Setting ;

2) How to set the low voltage protection of DC output ?

This controller have low voltage protection ,the magnitude of low voltage protection

              Could be set based on customer’s need . Factory settings is 10.5 V for 1 battery .If the DC output is under the State of providing power for load ,then when the voltage under the magnitude of low voltage protection , the DC output will stop provide power for load . When the voltage of battery is recover to 0.5V bigger the magnitude of low voltage protection ,it will restart . For 48V system , if the DC output under on mode , then when the battery bank will stop provide power under 42V , it will restart when the voltage recover to 42.5 V .

3) Max DC output current

Then Max DC output current is 50A , if the output current out the rated current ,the built-in fuse will be burn . We provide 2 fuse as back up ;

5.2.5 MPPT controller work step

Please make sure the MPPT had already been connected in right way .       

Step 1 : Open the breaker that connect with battery , make sure the MPPT controller had been connect with with the battery .( When all this done ,the LED and LCD will show some information )

Step 2 :Turn on the breaker that connect with PV module , if the PV module voltage is in the charging range , then machine will start to work .

Step 3 : If need DC load control , please set the DC output control mode , then turn on the DC output breaker .

5.2.6 The step of turn off machine

 Step 1 : Turn off the PV input breaker ,make sure PV and controller disconnect .

Step 2: Turn off the battery breaker , the machine will be complete off .

6、Meaning of LED/LCD and function key

6.1  Panel Description

Meaning of LED and function key

ALARM (Red）  -----  Alarm Light ( Red , when controller in fault state this light    

will on . )

CHANGE(Blue)   -----  Charging Light ( Blue ,when controller start to charge power ,this light will on .)

LOAD(Green)------- Load Light (Green , when the DC load turn on ,this load will on )

6.2 Charge Mode

This controller have 3 mode :Constant charging stage ( CC Mode ) , Constant voltage charging stage ( CV Mode ) , Floating charge Stage ( FC Mode ) :

In CC Mode ,the blue light will flash for every second .

In CV Mode ,the blue light will flash for every 3 second .

In CF Mode ,the light will keep on .

( Note : Charging Mode also could check in LCD and solar eagle .)
