Home Outdoor Camping Power Bank Pack 10W solar portable power stations

System introduction：

This product uses portable design, built-in battery and solar power controller, which is dedicated to supply the power to  small power DC load ;Solar controller process the sample of the battery terminal voltage, discharge current, environment temperature, involving the battery capacity parameters  through the computer chips. Through the special control model calculation, implementation conforms to the characteristics of battery discharge rate, temperature compensation correction of high efficiency, high control accuracy, and adopt the efficient PWM battery charging mode, which can ensure the battery work in the best state, in order to greatly extend the service life of battery.System comes with 12 VDC or 5 VDC output terminal, with short circuit, overload, unique reverse, full of, discharge automatically shut off, and restore full function protection measures;Detailed charging indicator, battery status, load, and various fault indicator.

Main features：
1, the single chip microcomputer intelligent control, optimize the SOC algorithm.
2, the built-in temperature sensor, which can effectively increase the built-in battery charging efficiency.
3, with the charge and discharge, electronic short circuit protection, overload protection, automatic control for the protection of the unique reverse.
4, main circuit adopted tandem PWM charging, which made the charging circuit of voltage loss than using diode charging circuit to reduce the nearly half, charging efficiency is  higher 3%-6% than the non-PWM , increases the utilization of time.
5, put the ascension of charging, normal straight charger, floating automatic control method make the system have a longer service life.
6, intuitive digital pipe + LED display system.

Charging status indicator：

When the system normally connected to the solar panels, and the sun to the solar panel, charging status indicator for the green normally on "DISCHA", which said the system charging circuit is normal;"CHA" appears that the charging status indicator light green flashing, showing system is overvoltage, see troubleshooting content.When charging process used the PWM mode, if appear the action of over discharge, charging voltage need to reach the voltage of overcharge protection first, and keep an hour, and then to float charging voltage, to activate the battery, avoid sulfide crystallization, if not happened, there will be no increase charging ways, in case the battery fluid loss.The automatic control process will make the battery charged the best effect and guarantee or prolong its service life.

Discharging status indicator ：

When the battery voltage is in the normal range, the discharge lstatus indicator "CHA"is orange normally on;When the battery voltage goes down to the over-discharge protection and goes out;The controller will automatically shut down output, to alert users to timely supplement energy.When the battery voltage return to normal scope of work, it will automatically open output, status indicators become orange normally on;When an external load is overload or short circuit, discharge status indicators in the flash state, DC output shut down, automatically recover after 30s, after again to detect overload or short circuit,you must disconnect the switch between solar panels and power and then restart.
