I.Brief Instructions

GSM series solar controller is a highperformance Buck solar power equipment,
using MPPT (Maximum Power Point Tracking) algorithm makes full use of solar photovoltaic energy.
PV input voltage range, for a variety of battery charging, and threestage charging effectively improve the battery life.
The modular design of the controller, you can use more than one parallel, allowing customers the freedom and flexibility to configure.

II.Safety

~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.

Due to high input working voltage, please be cautious, otherwise it is danger to life.

The appliance is not to be used by children or persons with reduced physical sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction.

Energy stored in capacitors will remain alive for 5 minutes; don't touch within the period after disconnection. Both the sides have circuit lines, disconnect both and don't operate within 5 minutes after disconnection

Ensure input DC voltage no more than Max. DC voltage .Over voltage may cause permanent damage to solar charge controller or other losses, which will not be included in warranty!

III.MPPT controller working steps

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 .
 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 .

IV.Meaning of LED and function key

ALARM (Red):Alarm Light ( Red , when controller in fault state this lightwill 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 )
UP:UP Function Key (For check or page up and numerical increase )
DOWN:DOWN Function Key ( For check or page up and numerical reduction )
ENTER :ENTER key ( For enter in  )
ESC:ESC Key  ( For exit and save data )
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.)

V.Recovery Processing and Warranty

Recovery Processing
When the controller abnormal, please check the following question and contact the customer service representative.
Please check the fault tips in the failure mode, and then proceed to the appropriate troubleshooting; When the controller does not start properly:
1. Check the controller external solar panels with the correct polarity.
2. Check Battery Connection;
3. Check Battery;
4. Check circuit breaker;
5. Check internal fuse;
If the problem persists , please contact the customer service;
Please offer the following information:Equipment information and Detailed description of the problem.

Warranty
Within the warranty period, it is free to repair for the non-human fault. Otherwise, should charge the cost of repairs.
