BRAVO Waterproof 10 — 10 Amp PWM Waterproof Solar Charge Controller
The BRAVO Waterproof 10 is a 12V PWM charge controller rated for 10 amps of solar input, built with the same IP65-rated, conformal-coated, no-spark waterproof construction used across Rich Solar's BRAVO lineup. It includes an optional external Battery Temperature Sensor (BTS) port for more accurate temperature-compensated charging, and DIP-switch battery selection across Flooded, AGM, GEL, and Lithium (LiFePO4) chemistries — a solid step up from the entry-level BRAVO 8 for slightly larger single or dual-panel 12V systems.
10A Capacity, a Step Up From Single-Panel Scale
M5 terminals accepting up to #10AWG wire and a 5A soft-start charging current give this controller more headroom than the entry-level BRAVO 8 — a comfortable fit for a single larger panel or a small two-panel 12V array.
IP65 Waterproof, Solid-Duty Cables
Conformal coating protects the internal board against moisture, corrosion-resistant terminals hold up in damp environments, and solid-duty cables handle this controller's current load — all rated IP65 for genuinely exposed mounting.
Optional External Battery Temperature Sensor Port
Includes a port for an optional external Battery Temperature Sensor (BTS) — adding the sensor gives the controller a direct read on the battery's actual temperature, rather than relying solely on onboard ambient sensing near the controller.
Product Overview
The BRAVO Waterproof 10 is a 12V PWM charge controller rated for 10 amps of solar input, sharing the same core waterproof construction found across Rich Solar's BRAVO line: conformal coating on the internal board, corrosion-resistant terminals and connectors, solid-duty cables, and an overall IP65 rating suited to genuinely exposed mounting on boats, RVs, and other mobile installations rather than requiring a sealed indoor enclosure.
Battery type — Flooded (WET), AGM, GEL, or Lithium (LiFePO4) — is set via a physical DIP switch. The controller includes a port for an optional external Battery Temperature Sensor (BTS), giving it a direct read on the battery's actual temperature when the sensor is added, rather than relying solely on ambient sensing near the controller itself. Smart charging control, charging time management, and an equalization stage at 15.5V±0.2VDC with a 2-hour timeout round out the charging features, alongside battery temperature compensation of -24mV/°C across a -4°F to 122°F range.
Physically, the BRAVO 10 uses the same M5 terminals and #10AWG wire capacity as the BRAVO 20 and BRAVO 30, rather than the smaller BRAVO 8's M4/#12AWG terminals — a meaningful upgrade in wiring headroom even at this lower current rating. The controller weighs approximately 0.66 lb, mounts vertically using three included plastic spacers and self-tapping screws, and includes protection against overvoltage, short circuit, reverse polarity, and thermal conditions (engaging at 149°F).
Built to Handle Real Moisture Exposure
- IP65 Waterproof Rating: Protected against dust ingress and water jets, suitable for mounting in exposed locations rather than requiring a sealed enclosure.
- Conformal-Coated Internal Board: Protective coating applied directly to the circuit board guards against moisture-related corrosion and short circuits internally.
- Solid-Duty Cables: Built for this controller's current load, matched to the wiring approach used across the BRAVO 20 and 30.
- Corrosion-Resistant Terminals and Connectors: Maintains reliable electrical connections even in damp or salt-air environments over time.
- No Sparks Design: A meaningful safety feature for installations near fuel sources, such as boat engine compartments or generator areas.
Configurable Charging With Optional Remote Sensing
- DIP Switch Battery Selection: Configure for Flooded (WET), AGM, GEL, or Lithium (LiFePO4) batteries with a simple physical switch.
- External BTS Port (Optional): Connect an optional external Battery Temperature Sensor for direct battery temperature readings rather than relying on the controller's onboard ambient sensing alone.
- Battery Temperature Compensation: Adjusts charging voltage by -24mV/°C across a -4°F to 122°F range.
- Equalization Charging: 15.5V±0.2VDC (25°C) stage with a 2-hour timeout for periodic deep maintenance charging on flooded lead-acid batteries.
- 5A Soft-Start Charging Current: Handles the initial charging ramp-up at up to 5A (50% PWM duty) before reaching full charging current.
Protected Operation, Upgraded Terminal Sizing
- Overvoltage, Short Circuit & Reverse Polarity Protection: Covers the most common fault conditions for a PWM controller in field use.
- Thermal Protection During Charging: Engages at 149°F to protect the controller and connected battery.
- M5 Terminals, Up to #10AWG Wire: A step up from the smaller BRAVO 8's M4/#12AWG terminals, matching the wiring capacity of the larger BRAVO 20 and 30.
- Vertical Wall Mounting: Mounts using three included plastic spacers and self-tapping screws — no additional mounting hardware needed.
- Wide Environmental Range: Operating temperature of -13°F to 122°F and storage temperature of -40°F to 185°F.
