48V 6kw/120A Mppt Solar Controller with RS485 Optional

Product Specifications/Features
    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.

    Using industrial-grade materials to ensure stable and reliable equipment.
    Memory function, save the settings, date and time, power generation, and other functions charging: three-stage charging (constant current, float), effectively extending the battery life.
    LCD and LED Display various parameters, such as type, PV input voltage, the battery type, the charging voltage, charging current, charging power, working condition, etc.
    Using MPPT PV input tracking technology to automatically make PV power generation in the best spot.
    Multiple devices can be run in parallel, the expansion of the scope of use to meet the requirements of high-power charging.


    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!


    Environment Condition
    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 -10 °C and +50 °C to guarantee optimal operation.
    Do not expose the charge controller to direct sunlight to avoid power losses due to overheating.
    The controller can work under the 1000 meters elevation height.If more than 1000 meters, it must reduce rated power.

    Caution : Please follow the steps ,or the machine will be easy to broke.

    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 .
