Y&H 60A MPPT Solar Charge Controller 12V/24V with Double USB Port, LCD Display Panel

The solar controller is only suitable for lead batteries: OPEN, AGM, GEL. It is also suitable for Ni-MH, Li-ion or other batteries. 【Package Includes:1 x MPPT Solar Charge Controller,1 x English User Manual】 There are many types of MPPT technology, our solar controller MPPT technology detects the maximum charging current, not the boost type or the automatic charging of the voltage of the solar panel. Compared to the normal solar charge controller, this MPPT controller could increase the efficiency by 10% -30%. When the battery voltage is low, the controller automatically interrupts the charge from the system. When the battery voltage is back to normal, the load will work again. This MPPT controller has a perfect SOC function, controls the charging current and powering the loads. Prevents the battery from overcharging, over-discharging and sending the charge to the solar panels during the nights. Q:My solar panel is 36V 200W, can I charge the battery with 12V? R: To charge a 12V battery, the operating voltage of the solar panel can be between 17V and 23V (Voc), and for a 24V battery, the operating voltage of the solar panel can be between 36V and 46V. Ensure that the operating voltage of the power supply and solar panels is within this range. If it is too high, the controller will be damaged.
