Description: MorningStar SunGuard 4.5 Amp 12 Volt PWM Charge Controller Manufacturer Part Number: SG-4 Morningstar's SunGuard SG-4 is the world's leading single module controller. We have combined all the advantages of our SunSaver charging circuit with less expensive packaging to provide an economical controller for small PV systems. Morningstar’s SunGuard is the most advanced small, economical solar charge controller on the market today.SunGuard’s technology provides:Exceptional ReliabilityPWM Battery ChargingConsistent High QualityLow CostFeaturesISO 9002 quality programsSeries design (not shunt)100% solid stateTrue 0 to 100% PWM duty cycleSetpoint accuracy to 60 mVTemperature compensation: A sensor measures ambienttemperature and corrects the constant voltage setpoint by–28 mV per °C with a 25°C reference. This works best if theSunGuard and battery are in a similar thermal environment.Rated for 25% overloadsNo need to derateLightning protected with 1500 W transorbsSelf-consumption is 6 mAFully encapsulated in epoxy pottingABS plastic, impact-resistant caseOutdoor rated, Hypalon connecting wiresAdvantages SunGuard can be mounted outdoors. Do not expose to ambient temperatures above 60°C. Make sure that water will drain from inside the case. SunGuard’s PWM charging comparedto On-Off solar regulators:Typically 30% more solar energy intothe battery per dayAverage battery State-of-Charge is90 – 95% compared to 55 – 60% forOn-Off regulatorsSpecificationsRated Solar Input 4.5 AmpsMax.

Compensation–28 mV/°CReverse Current Leakage<10 uAOperating Temperature –40 to +85°CWire Size#16 AWGDetailed Description The MorningStar SunGuard is a fully epoxy encapsulated outdoor rated 4.5A "ice cube" sized 12V PWM charge controller. It has built-in temperature compensation, lightning protection and easy 4-wire hookup. The SunGuard's regulation voltage is set at 14.1 (best for sealed or gel batteries) and is not adjustable for battery type like MorningStar's other controllers. It's dimensions are 2.5" x 2.0" x 1.5" and it weighs just 3 oz. Use only with a 12 volt battery. The SunGuard is able to match the quality andperformance of the world-leading SunSavercontrollers because:SunGuards are made on the same highspeed, automated production linesSunGuards use the same charging circuitSunGuards use the same high qualitycomponentsAdvanced PWM Battery Charging SunGuard uses an advanced series PWM charge control for constant voltage charging. A true 0 to 100% PWM duty cycle is very fast and stable for highly efficient charging.The SunGuard prevents the battery from discharging through the solar array at night. There is no need to install a blocking diode for this purpose.
