Characteristics
Rated for 6.5, 10 and 20 A (12 V and 24 V), the SunLight™ is priced lower than competitive PV regulators. Yet, the SunLight™ includes standard features and capabilities not found in any other small PV controller. These include:
Extremely high reliability
- Full, continuous current ratings at 60 °C ambient temperatures
- Advanced lightning and transient overvoltage protection
- Reverse polarity protection
- High quality surface-mount components
- Series switching design for improved safety and protection
Outstanding PWM battery charge control
- Proven increase in battery operating life
- PWM Pulse charging for highest charge acceptance
- Standard temperature compensation
- Standard sealed/flooded battery select at the terminal
- Accuracy to millivolt levels
Highest levels of quality
- Approved for use in Hazardous Locations: Class 1, Div. 2, Groups A-D
- Built in a world class ISO 9002 certified facility
- Automated production so every unit is exactly the same
- Parts soldered to .0006 inch accuracy
- Anodized case, marine terminals, custom potting material
Operation
- Rotary digital switch to select among 10 lighting options
- Test button flashes red LED to confirm correct rotary switch selection
- Test button turns lights on for 5 minutes (in LVD limited to 3 times)
- LVD overrides lighting timer
- Sunrise overrides lighting timer
- Timer accuracy is within 2 seconds
