BRAVO Waterproof 30 — 30 Amp PWM Waterproof Solar Charge Controller
The BRAVO Waterproof 30 is a fully waterproof 12V PWM charge controller rated for 30 amps of solar input, built for off-grid systems where moisture exposure rules out a standard indoor-only controller. With an IP65 rating, conformal-coated internal board, solid-duty cables, corrosion-resistant terminals, and DIP-switch battery type selection across Flooded, AGM, GEL, and Lithium (LiFePO4) chemistries, it handles meaningfully more panel wattage than the smaller BRAVO 8 while keeping the same exposed-installation durability.
30A Capacity, Built for Larger Single-Panel Arrays
Steps up from the BRAVO 8's small single-panel scale to handle meaningfully larger 12V arrays, with M5 terminals accepting up to #10AWG wire and a soft-start charging current of up to 15A to handle the higher current load without stressing the connected battery.
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 are built for the higher current this controller handles — all rated IP65 for genuinely exposed mounting locations.
Optional External Battery Temperature Sensor Port
Unlike the smaller BRAVO 8, this controller includes a port for an optional external Battery Temperature Sensor (BTS) — adding the sensor lets the controller adjust charging voltage based on the battery's actual temperature rather than ambient conditions near the controller itself.
Product Overview
The BRAVO Waterproof 30 is a 12V PWM charge controller rated for 30 amps of solar input — the larger sibling to Rich Solar's BRAVO Waterproof 8, built around the same waterproof construction philosophy but scaled up for a meaningfully bigger single-panel or small multi-panel 12V array. Conformal coating on the internal board, corrosion-resistant terminals and connectors, and solid-duty cables combine for an IP65 rating, supporting genuinely exposed mounting on boats, RVs, and other mobile installations where a standard indoor-only controller wouldn't hold up.
Battery type — Flooded (WET), AGM, GEL, or Lithium (LiFePO4) — is set via a physical DIP switch, the same straightforward configuration approach used across Rich Solar's BRAVO line. The controller includes smart charging control, charging time management, and an equalization stage at 15.5V±0.2VDC with a 2-hour timeout. One feature that distinguishes the BRAVO 30 from the smaller BRAVO 8: a port for an optional external Battery Temperature Sensor (BTS), which, when added, gives the controller a direct read on the battery's actual temperature rather than relying solely on the onboard sensor near the controller — a more accurate basis for temperature-compensated charging, particularly when the battery is mounted some distance from the controller.
Protection circuitry covers overvoltage, short circuit, reverse polarity, and thermal conditions (engaging at 149°F), with a no-spark design relevant to fuel-adjacent installations like boat engine compartments. The controller mounts vertically using three included plastic spacers and self-tapping screws, accepts up to #10AWG stranded wire at its M5 terminals with a specified torque of up to 17 in-lb, and weighs approximately 0.66 lb.
Built to Handle Real Moisture Exposure at Higher Current
- 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 the higher current this 30A controller handles, a step up from the lighter-duty wiring suited to the smaller BRAVO 8.
- 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.
More Accurate Charging With an Optional Remote Sensor
- 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 — more accurate when paired with the optional BTS, especially if the battery is mounted away from the controller.
- Equalization Charging: 15.5V±0.2VDC (25°C) stage with a 2-hour timeout for periodic deep maintenance charging on flooded lead-acid batteries.
- 15A Soft-Start Charging Current: Handles the initial charging ramp-up at up to 15A (50% PWM duty) before reaching full charging current.
Protected Operation, Heavier-Duty Terminals
- 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: Heavier-gauge terminal capacity than the BRAVO 8's M4/#12AWG terminals, matched to this controller's higher current rating.
- Specified Terminal Torque: Up to 17 in-lb (1.92 N·m) — follow this spec when wiring to ensure a secure, properly torqued connection.
- Vertical Wall Mounting: Mounts using three included plastic spacers and self-tapping screws — no additional mounting hardware needed.
