CHARGE CONTROLLER - Product
Place of Origin : Karachi,Pakistan
Product Description
Charge controller is basically used to charge solar batteries from Solar Panels. Solar panels normal give 15-17 volt, charge controller converts that to 12-14 volt and charges battery. Battery often need a higher voltage than it already have to charge the battery. Charge controller prevents batteries to be over charged. And stops to charge when battery is fully charged. And it will give longer life for battery. You can also use blocking diode instead of charge controller. But there are some n
Basic Information
Brand : Morningstar
Physical Specification
Other Specification :
Charge Controls Come In All Shapes, Sizes, Features, And Price Ranges. They Range From The Small 4.5 Amp (Sun Guard) Control, Up To The Apollo 80 Amp MPPT Programmable Controller With Computer Interface. Often, If Currents Over 40 Amps Are Required, Two Or More 20 To 40 Amp Units Are Wired In Parallel. The Most Common Controls Used For All Battery Based Systems Are In The 6 To 40 Amp Range.
What Is Equalization?
Equalization Does Somewhat What The Name Implies - It Attempts To Equalize - Or Make All Cells In The Battery Or Battery Bank Of Exactly Equal Charge. Essentially It Is A Period Of Overcharge, Usually In The 15 To 15.5 Volt Range. If You Have Some Cells In The String Lower Than Others, It Will Bring Them All Up To Full Capacity. In Flooded Batteries, It Also Serves The Important Function Of Stirring Up The Liquid In The Batteries By Causing Gas Bubbles. Of Course, In An RV Or Boat, This Does Not Usually Do Much For You Unless You Have Been Parked For Months, As Normal Movement Will Accomplish The Same Thing. Also, In Systems With Small Panels You May Not Get Enough Current To Really Do Much Bubbling.
Simple 1 Or 2 Stage Controls Which Rely On Relays Or Shunt Transistors To Control The Voltage In One Or Two Steps. These Essentially Just Short Or Disconnect The Solar Panel When A Certain Voltage Is Reached. For All Practical Purposes These Are Dinosaurs, But You Still See A Few On Old Systems. Their Only Real Claim To Fame Is Their Reliability - They Have So Few Components, There Is Not Much To Break.
3-stage And/or PWM Such Morningstar, Xantrex, BZ Products, Blue Sky, Steca, And Many Others. These Are Pretty Much The Industry Standard Now, But You Will Occasionally Still See Some Of The Older Shunt/relay Types Around, Such As In The Very Cheap Systems Offered By Discounters And Mass Marketers.
