Product Description
Morningstar's SunGuard is the most advanced small, economical solar charge controller on the market today. Rated for 4.5 Amps, the SunGuard delivers the same quality and performance as Morningstar's world-leading SunSaver controllers. The SunGuard's technology provides exceptional reliability, PWM battery charging, consistent high quality (ISO 9002) and low cost. The SunGuard is an ideal battery charger for single module power systems. It is well-suited for numerous off-grid solar applications including remote instrumentation, rural telephones, supervisory control and data acquisition (SCADA), traffic signals and consumer uses. This controller is ideal for single panel installations for panels of up to 60 watts. This is also what we recommend for the smaller trickle charge and maintenance charge panels in the 1 to 20 watt range if you require one. Features: ISO 9002 quality programs Series design (not shunt) 100% solid state True 0 to 100% PWM duty cycle Setpoint accuracy to 60mV Temperature compensation Uses SunSaver's battery charging circuit Rated for 25% overloads No need to de rate Lightning protected with 1500W transorbs Self-consumption is 6 mA Fully encapsulated in epoxy potting ABS plastic, impact resistant case Outdoor rated, Hypalon connecting wires. All weather resistant Sunguard's PWM charging, when compared to On-Off solar regulators, delivers: Typically 30% more solar energy into the battery per day Average battery Sate-of-Charge is 90 - 95% compared to 55 - 60% for On-Off regulators. Mechanical Specifications: Wire Size #16 AWG ABS plastic case Epoxy encapsulated Weight is 90 g Electrical Specifications: Rated Solar Input 4.5A Max. Input (5 min) 5.5A System Voltage 12V Max. Solar Voltage 30V Regulation Voltage 14.1V Accuracy 60mV Self-consumption 6mA Temp. Compensation -28mV/oC Reverse current leakage under 0.01mA Operating Temperature -40 to +85oC
