100W/50Ah small solar DC power system with built-in battery LED

Model Number: DL-50Ah-Y1 Brand Name: Seasun Key Specifications/Special Features: Product specifications:-Solar panel: 100W-Controller: 12V/10Ah.-Battery: 1*12V/50Ah-5*12V DC outlets.-1*USB outlets (5V/2A).-4 LED bulbs.-1*multi-plug USB phone charger.Main features:
-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, overdischarge 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 overdischarge, normal direct charge and floating charge
-Visualized display of the system status by nixie tube and LEDs.
