solar controller CE certification maximum efficiency with MCUand PWM special anti-reverse protect waterproof function

                                                                       

Characteristics:

Control circuit:use MCU and professional software as the control center to fulfill intelligent system control.

Charging mode: use PWM high efficiency charging way. Boost, recovery and float charging auto work for battery long-life. Use temperature compensation.  

High accuracy over discharging control by the discharging rate: Over-discharging control voltage modified by the battery discharging rate curve.

Self protection: protection to overload, outside and inside short circuit, reverse connection, thunder and lightning, PV panel reverse current, over charging and discharging etc. during the short circuit and overload protection, no any component will be damaged and need change, include fuse.

LED indication on system condition: LED indicating the system of charging, overcharge, power full, power low, over-discharge, over load, out short circuit, load on/off, etc.

Industry level production standard: wide temperature running area -35°C to +50°C

No adjustable hardware part: use flash memory to save all work control point instead of adjustable resistance, to protect the control work point from going off as the adjustable resistance value is easily changed by temperature and vibration, in order to make sure the control accuracy and reliability.

Operation: easy to operate, robust in design
