Solar Charge Controllers

DESCRIPTION:

DESCRIPTION PV Charge Controller is designed for use with all types of pv panels and different types of batteries such as wet or sealed lead acid, lead calcium, lead antimony battery User Adjustable Charge Control Settings for different types of batteries Informative LCD Display and Tri-Color LED indication of system and battery conditions

3 STAGES OF CHARGE CYCLE:

3 STAGES OF CHARGE CYCLE  BULK :  During this phase the voltage gradually rises to the Bulk level while the batteries draw maximum current.  ABSORPTION :  During this phase the voltage is maintained at Bulk voltage level for a specified time while the current gradually tapers off as the batteries charge up.  FLOAT :  After the absorption time passes the voltage is lowered to float level and the batteries draw a small maintenance current until the next cycle.

USES Prevents battery overcharge Blocks reverse current Prevent over-discharge from batteries (some models) Prevent electrical overload (some models) Displays battery status Medors.in

PROS AND CONS:

PROS AND CONS PROS Short-Circuit Protection at load terminal Optimal temperature Sensor for compensated battery charging Overcharge and Over-discharge Protection, Over Temperature Protection User Adjustable Low Voltage Disconnect and Low Voltage Reconnect

CONS:

CONS Equalization Charging is only for Wet-type Lead Acid Battery Automatic Equalization charge is only available when battery voltage is higher than the Low Voltage Disconnect (LVD)  No disconnection from the battery should ever occur.
