40A Solar Charger Controller 12V 24V Auto PWM Controllers LCD Display 5V Dual USB Output Controller

• Multiple Protection Functions: Binen solar controller has short-circuit protection, open-circuit protection,reverse protection, over-load protection. Fully 3-stage PWM charge management, improve system efficiency and prolong the life span of the battery.
• ☀☀☀Battery Type: The charge regulator is only suitable for lead-acid batteries: OPEN, AGM, GEL, it is not suited for nickel hydride, lithium, Liions, or other batteries. For protecting the lifespan of your battery, once the voltage of the battery drop below 8V, the solar controller will turn off automatically.
• ☀☀☀LCD Display: Comes with a display that can clearly indicate the status and data, it can be conveniently switched modes and parameter configuration, suitable for home, industrial, commercial etc.
• ☀☀☀Easy to Install and Operate: The charge controller should connect the battery first, then the solar panel, and finally the load! The disassembly sequence is contrary to the wiring order.Dual mosfet Reverse current protection, low heat production. ( Note: The charge controller will heat up when it is running. Please be careful to install the charger controller on a flat, well-ventilated place)

Dual USB output (5V/2A), this solar charge controller can simultaneously charge or supply power to two mobile phones, tablet PCs and other devices that require 5V power 
3. Using series PWM main charging circuit, effectively improve the charging efficiency 
4. Improved LCD display, more intuitive to adjust the various parameters 
5. Quality assurance, this product uses SMT chip production process, adopts high-quality PCB and industrial-grade chip, can work in high temperature, low temperature, high humidity environment 

Safety Instructions: 
1. Make sure your battery has enough voltage for the controllers to recognize the battery type (12 V / 24 V) before installation. 
2. The battery cable should be as short as possible to minimize loss. 
3. The regulator is ONLY suitable for lead acid batteries: OPEN, AGM, GEL. (NOT suitable for lithium batteries, Ni-MH battery) 
4. ONLY suitable for working with photovoltaic solar panels. (NOT for other DC or AC power source)
