EPEVER 50A MPPT Solar Charge Controller 12V 24V 36V 48V Auto, 50 amp Solar Regulator with Automatically Identifying System Voltage, for Lead-Acid and Lithium Batteries

Tips:

• Always connect battery first!!! Make sure enough batteries’ voltage let controller recognize the right system voltage.
• DO NOT connect any Inverter / wind / Alternator or Charger into the charge controller! connect the Inverter directly to the battery.
• Ensures solar input voltage higher 3V or more than batteries’ voltage and total input power in the range. The charging current almost be zero when controller is floating charge. Parameter Setting Rules: Floating voltage > Low voltage reconnect > Low voltage discharge.
• The solar controller will stop output when the battery under 10.7V (adjustable).The LCD will be blank when the battery under 8V and it will re-output when the battery up to the 12.6V (adjustable).
• Install the Charger controller to the battery as close as possible to avoid voltage and power dropping caused by overlong wire and affect normal voltage judgment.
• Remove all the debris around the controller(Leaving a space of approx. 5.91in)
• WARNING: Do not reverse the polarity of the batteries. Because reverse polarity will damage the charge controller permanently！！！
