30 amp solar charge controller,12 volt smart sun power controller

30 amp solar charge controller,12 volt smart sun power controller   1. Features: Control Circuit: Micro Controller Unit utilizing dedicated software and SCM for precise control. Charging mode: Pulse Width Modulated control, allows for high efficiency boost, recovery and float charging. Temperature compensation ensures that these parameters are adjusted for maximum battery condition and hence, prolonged battery life. High accuracy discharging control: Over-discharging control voltage modified by the battery discharging rate curve.  Circuit Protection: protection against overload, short circuit and reverse connection, Built in Transient Voltage Suppression protects against lightning. Reverse current leakage through PV panel is blocked. Batteries are prevented from over-charging or discharging. LED indication on system condition: Indicating LED’s, monitor battery charging levels as well as battery state. LED monitoring of load conditions such as over load and short circuit as well as load on/off, are also provided. Industry level standard: Operating temperature range from -35 to +50 deg C. No adjustable hardware part: Controller accuracy, stability and reliability is assured by the use of flash memory for all control parameters and set-points. Operation and Design: easy to operate, Press button with LED number display.   2. Specification:
