300W portable solar power system, with built-in battery and 2*USB phone charger

Model Number: AL-300W-660-Y Brand Name: Seasun Key Specifications/Special Features: Product specifications:-DC system voltage: 12V-Battery: 1*12V/55Ah-Inverter: 12VDC/220(120)V AC 300W 50(60)Hz-Controller: 12V/30A-2*12V DC outlets-2*USB outlets (5V/2A)-1*220(120)AC outlet-Solar panel: 18V/100W
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, 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.
