Solar power system is a portable product for supply power for small-power loads.It has a built-in battery and a built-in solar controller.The solar controller samples parameters such as the battery's terminal voltage and capacity,the discharge current and the ambient temperature with help of a computer chip and computes through a special control module to realize efficient and accurate control over the discharge rate and the temperature compensation in line with characteristics of the battery.With an efficient PWM charge mode,the battery can operate in the best status and have a long life.The system has a 12VDC output terminal and a 5VDC output terminal,overall protection such as short circuit protection,overload protection,unique reverse connection prevention,automatic shutoff upon full charge or overdischarge,detailed charge indication,battery status indication,load indication and fault indication.
1.SCM intelligent control and optimization SOC algorithm
2.Built-in temperature sensor which can improve charge efficiency of the built-in battery effectively
3.Full-automatic control such as overcharge protection,overdischarge protection,electronic circuit short circuit protection,overload protection and unique reverse connection prevention
4.A serial-connection PWM charge main circuit which makes voltage loss of the charge circuit less than that of the charge efficiency 3% to 6% higher than a non-PWM charge main circuit and increases the time of power consumption
5.A longer life contributed by automatic control modes including boosting charge for recovery from overdischarge,normal direct charge and floating charge
6.Visualized display of the system status by nixie tube and LEDs.
