Yannee 30A MPPT Solar Panel Charge Controller Battery Regulator DC12/24V Dual-USB

Safety Instructions: 1.Controller Provided MPPT Maximum power point tracking Function charging mode is PWM Make sure your battery has enough voltage for the controller to recognize the battery type before first installation. The battery cable should be as short as possible to minimize loss. 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. The charge regulator is only suitable for regulating solar modules. Never connect another charging source to the charge regulator. System Connection: 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. Connect the photovoltaic module to the regulator - plus and minus. Connect the consumer to the charge regulator - plus and minus. -Automatic identification system voltage 12/24V auto recognition. -Humanized LCD display and double button operation of man-machine interface. -Completed technical data for setup and modify. -The load control mode can be selected the timer function can be reset for street light at night. -Discharge capacity control. -Discharge counter of ampere hour. -Charge model: PWM -Working storage function: record the total run time of system record timers of error during running time record times of full charged battery. -Reliable over voltage protection short circuit protection over load protection overcharge protection over-discharge protection. -Accurate temperature compensation correcting the charging and discharging voltage automatically improving the battery lifetime. -Roundly reverse connected protection. -Solar panels battery solar charge controller positive poles are all connected together adopting negative MOSFET in series control circuit.
