Solar Charger Controller Intelligent solar panel charge controller with LCD display & USB port, overcurrent protection, solar charge regulator for solar panel battery lamp LED lighting (12V-24V 40A)

Common Q&A How to install? A: (1)Battery --->(2)Solar panels ---> (3)DC load. Disconnect order is (1)DC load --->(2)Solar panels ---> (3) Battery Q: What battery type is this controller supported? A: Pay attention to this regulator is only suitable for lead acid batteries: OPEN, AGM, GEL, not for nickel hydride, lithium, ions, or other batteries. Q: Why the LCD screen become blank? A: When the battery voltage is too low, the controller will stop to output ( ? 8V, controller turns itself off, LCD is blank, ? 10.7V (default), 12V output ports are not available); after the solar panels charging, it will re-output when the battery will return to 12.6V(default). Q: Why does the controller display 14.4V? A: If the solar charge controller is set to 12V, when the battery voltage reaches 14.4V or 14.5V, the solar charge controller will stop charging and play a protective role. If it does not enter the floating state, please don't worry, the solar charge controller has a voltage limit value, will be not charge if the battery voltage reaches to 14.4V or 14.5V. Note: <1> Make sure the voltage of your battery reach 11V for initial use , so as to start up for the controller to registered the battery type accordingly. <2> Old batteries may be degraded the capacity after hundereds of cycles, easily drop lower than 8V, which results in the controller will be shut off (LCD screen become totally ?DEAD?). <3> Indoor use only: the working temperature of this controller is -35°C to +60°C. During hot sunny days, the temperature outside might go up to 60-75°C. Please do keep the controller stay in cool and well-ventilated place to maintain good heat dissipation Package List: 1 x Solar Charge Controller

• Wide Compatibility: The solar charger controller with 30A rated discharge current is compatible with 12V or 24V system automatically, suitable for lead-acid batteries: OPEN, AGM, GEL. Dual USB 5V/3A output ports support mobile phones, tablet PCs or other devices that require 5V voltage.
• Reliable Protection: The solar charge regulator provides over-current protection, short-circuit protection, inverse connection protection, low voltage and overcharge protection, a reliable protector for your devices.
• Intelligent: Build-in industrial microcontroller for automatical management, memorizing various parameters set by the user and the data won't be lost when the battery runs out. The solar controller will turn off automatically once the voltage is too low.
• Functional LCD Display: Intuitive LCD display that can clearly indicate the status and data is able to switch modes and parameter configuration, suitable for home, industrial, commercial, etc.
• Easy to Use: The charge controller should connect the battery first, then the solar panel, and finally the load! You can change the settings by the simple one-button operation.
