• Safety Instructions:  
• 1.Make sure your battery has enough voltage for the controller to recognize the battery type before first 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
• it is not suited for nickel metal hydride, lithium ions or other batteries.
• 4.The charge regulator is only suitable for regulating solar modules. Never connect another charging source to the charge regulator.
•

• 5.Dual mosfet Reverse current protections ,low heat productions.
•  
• System Connection:     
• 1.Connect the battery to the charge regulator - plus and minus.it will show 1 ,if it detects 12V battery, 2 if it detects 24V battery.
• 2.Connect the photovoltaic module to the regulator - plus and minus.
• 3. Connect the consumer to the charge regulator - plus and minus.
•  
• The reverse order applies when deinstalling!
• An improper sequence order can damage the controller!
