Description:    SOLAR30 20A\/30A 12V\/24V LCD Solar Controller Charge Controller PV Panel Battery Charger Controller Solar System Home Indoor Use  This Solar controller is a kind of intelligent and multifunctional solar charge controller. These serial products adopt customized LCD display screen、 which makes the operation on the interface rather convenient. All the controlling parameters can be reset flexibly to satisfy your different needs.  This controller has Light and Timer control Function   Light control: When daylight starts to occur then the light source goes off. Meanwhile the Solar Panels will charge the batteries. when there is no sunlight the garden light will switch on.   Time control: There is an eight hours time control、that means it will go off when the Lights automatically switch off after 0-15 hours.   Features:                - Visual LCD graphic symbol         - Brief key operation               - Grade auto switch of system voltage         - Intelligent PWM Charging Mode               - Auto temperature compensation         - Adjustable charging & discharging parameter               - Settable working modes of loads         - Accumulative function of charging & discharging AH               - Overloading & short-circuit protection         - Battery reversed protection               - Delayed auto restart after overloading protection         - Protection for battery low voltage               - Protection for battery back discharging                    Specification:      Model: SOLAR30    Rated Current: 20A\/30A   Rated Voltage: 12V\/24V    Maximum Voltage of solar panel: <48V    Float Voltage: 13.8V\/27.6V    Low Voltage Disconnection: 10.7V\/21.4V    Low Voltage Reconnection: 12.5V\/25V    No load loss: <30mA   loop voltage drop:<200mV   Charging Mode: PMW Mode   Temperature Compensation: -4mV\/Cell\/degre     Ideal for     For 12V PV system: 24V for Max input、360W Solar Panel.
