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 Reliability
  • PWM Battery Charging
  • Consistent High Quality
  • Low Cost
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: A sensor measures ambient temperature and corrects the constant voltage setpoint by –28 mV per °C with a 25°C reference. This works best if the SunGuard and battery are in a similar thermal environment.
  • 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
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
