Morningstar’s SunGuard is the most advanced
small, economical solar charge controller on
the market today.
SunGuard’s technology provides:
• Exceptional Reliability
• PWM Battery Charging
• Consistent High Quality
• Low Cost
The SunGuard is able to match the quality and
performance of the world-leading SunSaver
controllers because:
• SunGuards are made on the same high
speed, automated production lines
• SunGuards use the same charging circuit
• SunGuards use the same high quality
components

Features:
• ISO 9002 quality programs
• Series design (not shunt)
• 100% solid state
• True 0 to 100% PWM duty cycle
• Setpoint accuracy to 60 mV
• Temperature compensation
• Rated for 25% overloads
• No need to derate
• Lightning protected with 1500 W transorbs
• Self-consumption is 6 mA
• Fully encapsulated in epoxy potting
• ABS plastic, impact-resistant case
• Outdoor rated, Hypalon connecting wires

Advantages
SunGuard’s PWM charging compared
to On-Off solar regulators:
• Typically 30% more solar energy into
the battery per day
• Average battery State-of-Charge is
90 - 95% compared to 55 - 60% for
On-Off regulators
