40A LCD Display Solar Charge Controller 3S 6S Lithium ion 4S 8S Lifepo4 Lead Acid Battery Charging Regulator Parameter Adjustable with Dual 5V USB

Safety Instructions: A) Make sure your battery has enough voltage for the controller to recognize the battery type before first installation or adjusting default parameter, too low voltage battery won’t activate the controller. B) The solar charge controller can be charged for lead acid batteries (Sealed, Flooded, AGM, GEL),3S or 6S lithium ion and 4S or 8S lifepo4 batteries, but you need to confirm battery type as quick as possible after controller is activated. C) The charge controller is only suitable for regulating solar panels. Never connect another charging source to the charge regulator. D) Disconnect all sources of power to the controller before installing or adjusting, and don’t disconnect battery during charging, because it may causes a brief pike in load voltage which may damage sensitive equipment. E) The battery cable should be as short as possible to minimize loss. Use only well-isolated tools. F) Please keep it in cool and well-ventilated place to maintain good heat dissipation How to connect solar system with the controller: Step 1: Connect the battery to the solar charge controller firstly- plus and minus. Step 2: Connect the solar panel to the controller secondly. Step 3: Connect the load to the controller finally - plus and minus. The reverse order applies when de-installing.

• Can charge 3 types of batteries:3S/6S Lithium ion batteries, 4S/8S LiFepo4 batteries, and Lead acid batteries (including Flooded, Sealed, AGM, GEL), (Default battery type is for lead acid battery, customers need to set for other battery type)
• With multi-functional LCD display, it displays working modes, and parameter configuration can switched conveniently by pressing 3 yellow buttons.
• Have 3 kinds of load working mode for your choice: 24 hours load on mode, Dawn to Dark mode, and Timer mode based on D2D. (Default load working mode is 24 hours)
• Build-in industrial micro PWM solar controller,some voltages and working modes of loads can be adjustable.
• With dual 5V/2A max USB Output and deep heat sink, you can apply this solar charge regulator to many solar systems, such as solar street lighting, home power station, outdoor monitoring, RV, Camper,Boat or Caravan solar systems or other solar systems.
