Equipment Type: 10 Amp Waterproof PWM Solar Charge Controller
Primary Applications: Outdoor 12V battery charging for solar systems using flooded WET, AGM, GEL, calcium, or lithium batteries. The BRAVO Waterproof 10 is intended for installations requiring IP65 protection, positive grounding, and solar input up to 25VDC.
Performance Specifications
- Rated solar charging current: 10A maximum.
- Normal solar input: 15–22VDC; maximum open-circuit solar input: 25VDC.
- Minimum operating voltage: 8VDC at the solar or battery side.
- Minimum battery start voltage: 3VDC; soft-start range: 3–10VDC ±0.2VDC.
- Soft-start charging current: up to 5A at 50% PWM duty.
- Equalization voltage: 15.5V ±0.2V at 25°C; equalization timer: 2 hours.
- Maximum solar-to-battery voltage drop: 0.25VDC; night standby consumption: 5mA.
- Temperature compensation: -24mV/°C from -20 to +50°C (-4 to 122°F).
- Operating temperature: -25 to 50°C (-13 to 122°F); storage: -40 to 85°C (-40 to 185°F); operating humidity: 100% non-condensing.
Safety Features and Certifications
- IP65 enclosure, conformal-coated circuit board, spark-free connection, and thermal protection.
- Electronic protection against over-voltage, short circuit, reverse polarity, and over-temperature; charging over-temperature protection activates at 65°C (149°F).
- CE, EMC, and FCC compliant.
Installation and Maintenance Requirements
Mount vertically on a flat surface using the supplied three plastic spacers and self-tapping screws. Use M5 terminals with power wiring up to #10 AWG stranded or 5mm². Install in the stated operating environment and maintain connections and enclosure condition during service.
