Model Number: DL-12AH Brand Name: Seasun Key Specifications/Special Features: Model no.: DL-12AHSolar panel: 30WController: 12V/5A.Battery: 1*12V/12Ah.2*12V DC outlets.1*USB outlets (5V/2A).2*5W LED bulbs.1*multi-plugs USB phone charger.-SCM intelligent control and optimization SOC algorithm-Built-in temperature sensor which can improve charge efficiency of the built-in battery effectively-Full-automatic control, such as overcharge protection, over-discharge protection, electronic circuit short protection, overload protection and unique reverse connection prevention
-A serial-connection PWM charge main circuit which makes voltage loss of the charge circuit of a diode by nearly half and the charge efficiency 3% to 6% higher than a non-PWM charge main circuit and increases the time of power consumption
-A longer lifespan contributed by automatic control modes including boosting charge for recovery from over-discharge, normal direct charge and floating charge
-Visualized display of the system status by nixie tube and LEDs.
