Rich Solar Bravo 10A Waterproof PWM Solar Controller For RVs And Boats

Compact PWM Solar Battery Charge Controller

This compact PWM charge controller manages solar charging for 12V battery systems with efficient MOSFET switching, multiple safety protections, and selectable battery profiles. It’s built for reliable, low-maintenance operation in harsh environments and works with a wide range of lead?acid and LiFePO4 batteries.

Benefits

• Keep batteries healthy longer by using smart charging profiles that reduce overcharge and sulfation.
• Save energy and reduce power waste with low standby current and high-efficiency MOSFET switching.
• Install quickly and safely thanks to common positive grounding, robust terminals, and a simple mounting method.
• Understand system status at a glance with LED indicators for battery condition and charging progress.
• Protect equipment and avoid downtime with built-in thermal, overvoltage, short?circuit and reverse?polarity protections.

Features

• PWM charging technology with MOSFET switching control.
• Common positive grounding connection for simplified wiring.
• Battery type selection via DIP switch (supports multiple lead?acid and LiFePO4 profiles).
• Smart charging control with charging time management and soft?start behavior.
• LED indicators for battery condition and charging status.
• Thermal protection and over?temperature cutoff during charging.
• Overvoltage, short?circuit and reverse?polarity protection.
• Conformal coating on the internal board to protect against moisture.
• Waterproof enclosure (IP65) and corrosion?resistant terminals and connectors for outdoor use.
• Solid?duty cables/terminals to handle repeated connections without sparking.
• Optional external battery temperature sensor (BTS) port for temperature?compensated charging.
• Designed to meet CE, EMC and FCC standards.
