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.
* The single chip microcomputer intelligent control, optimize the SOC algorithm.
* The built-in temperature sensor, which can effectively increase the built-in battery charging efficiency.
* With the charge and discharge, electronic short circuit protection, overload protection, automatic control for the protection of the unique reverse.
* 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.
* Put the ascension of charging, normal straight charger, floating automatic control method make the system have a longer service life.
* Intuitive digital pipe + LED display system
