KMPA200JU SERIES MPPT Solar Charger With Constant Current Driver Professional for the solar street light system MPPT efficiency 99.9% Constant current driving power: 100W(12V), 200W(24V) Constant current driving efficiency up to 96% 3 Year Warranty Approvals: FEATURES High-Efficiency MPPT function : MPPT efficiency 99.9%. Integration of constant Current driver which can drive 200W(24V) LED. LED Driver start to drive LED with different current in different time phase. Battery capacity management function : When battery capacity discharge to the set value, LED driver will reduce driving current. In order to delay LED lighting time. In addition, it will make battery work in the Shallow discharge state. Charge function : It is three phase time charge battery, which contains MPPT charge, constant voltage charge and float charge. Flexible parameter set by Wireless infrared communication. Efficiency of charger and constant current driver is up to 96% by Synchronous rectification. Protect function : Battery reverse connection protection;battery under voltage protection;the solar panel reverse connection protection;to prevent the battery discharge to the solar panel;the LED output short circuit and open circuit protection. Ingress protection : IP67. Controller is no Aluminum electrolytic capacitor Design, extra long life extending to 25 years.
SYSTEM When the sun light has growing at dawn, solar controller knows the morning, they turn off the LED lights, and starting MPPT tracking to the solar panels, also then charge the battery. In the afternoon, as the battery voltage is getting higher and higher, MPPT controller has constant voltage charging, in the evening, the charging current has smaller and smaller, and finally into the constant voltage float. As the light has weak and weak, the solar charger knows to stop charging and then drive LED, this means Discharging has entered to the first time period, they drive LED lights has as per the drive current at first time period; Then charging has enter to the second time period, they drive LED lights has according to the drive current at second time period; finally into the third time period, they drive LED has according o the third time period current, it can discharge to the third time period or dawn.
