BRAVO 30A Waterproof PWM Solar Charge Controller
A compact, waterproof PWM charge controller that delivers efficient, safe charging for a wide range of rechargeable batteries. Designed for simple installation and reliable operation, it combines MOSFET switching, smart charging logic, and multiple protections so your battery system stays healthy and easy to manage.
Benefits
- Keep batteries healthy longer by preventing overcharge, overvoltage, and overheating.
- Spend less time troubleshooting with clear LED status indicators and built-in safety protections.
- Install quickly on any flat vertical surface using the supplied mounting spacers and screws.
- Use one controller for different battery types—no need for multiple chargers or complicated wiring.
- Operate confidently outdoors or in damp environments thanks to waterproof housing and corrosion-resistant terminals.
- Reduce wasted solar power with efficient PWM control that minimizes energy loss.
Features
- PWM charging with MOSFET switching for efficient current control.
- Common positive grounding connection.
- Low standby current and overall low power consumption.
- Battery-type selection via DIP switch for Flooded (WET), AGM, GEL, and LiFePO4.
- Smart multi-stage charging with timed equalization and charging time management.
- LED indicators showing battery condition and charging status.
- Thermal protection and over-temperature shutdown during charging.
- No-spark design and reverse-polarity protection for safe connections.
- Overvoltage and short-circuit protection.
- IP65-rated waterproof enclosure with conformal-coated internal board to resist moisture.
- Corrosion-resistant terminals and solid-duty cables for durable outdoor use.
- External port for an optional battery temperature sensor (BTS).
