BRAVO Waterproof 20 20A PWM Solar Charge Controller

Equipment Type and Primary Applications

The BRAVO Waterproof 20 is a 20A PWM solar charge controller for 12V battery systems in outdoor and moisture-prone installations. It regulates solar charging for Flooded (WET), AGM, GEL, Calcium, and lithium batteries, including systems requiring common positive grounding.

Performance Specifications

  • Rated solar charging current: maximum 20A.
  • Normal solar input range: 15–22VDC; maximum open-circuit PV input: 25VDC.
  • Lowest operating voltage at the solar or battery side: 8VDC.
  • Maximum solar-to-battery voltage drop: 0.25VDC; nighttime standby consumption: 5mA.
  • Soft-start charging: 3–10 ±0.2VDC, with up to 10A at 50% PWM duty.
  • Equalization charging: 15.5 ±0.2VDC at 25°C, with a 2-hour timer timeout.
  • Temperature compensation: -24mV/°C across -4°F to +122°F; charging over-temperature protection activates at 149°F.
  • Operating temperature: -25 to 50°C (-13 to 122°F); storage temperature: -40 to 85°C (-40 to 185°F).
  • Operating humidity: 100% non-condensing; enclosure rating: IP65.

Safety Features and Certifications

Electronic protection covers over-voltage, short circuit, reverse polarity, over-temperature, and thermal conditions. Spark-free battery connection improves installation safety. The controller is CE, EMC, and FCC compliant and uses a conformal-coated circuit board for moisture and corrosion resistance.

Installation and Maintenance Requirements

Install vertically on a flat surface using the supplied three plastic spacers and self-tapping screws. Connections use M5 terminals for up to #10 AWG or 5mm² stranded wire. Commission by mounting securely and connecting the 12V battery and solar array according to system polarity. Maintain by inspecting terminals, wiring, enclosure condition, and moisture exposure.
