    120V controller,

    120V controller,

     The principle frame of controller .

    SWC series products are the new generation MPPT controllers manufactured by our company . It is developed according to the latest technology , and on behalf of the latest developed level of PV technology , owning much excellent performance.   

        



    • l The controller is mainly used for off-grid solar power system (Independent system ) , Adopting the Max power tracking technology,  obtaining the Max power point of solar panel arrays through a built-in advanced tracking algorithm to charge batteries .
    • l The innovation technology of the Max power point tracking technology can significantly improve the utilization rate of the solar power energy system , The battery charging process of the controller has been optimized , which can prolong the service life of battery , improve the system performance
    • l The comprehensive self-testing function and electronic protect function can avoid the controller damage due to wrong installation and system fault .
    • l The RS485/RS232 interface of the controller provide the choice for monitoring the running state of the whole PV power system
