The Rich Solar BRAVO Weatherproof 10 (model RS-PWM10WP) is a 10 amp PWM solar charge controller for 12V battery systems. It handles up to 10A and 150W of solar, with a recommended input of 15V to 22V and a 25V open-circuit limit. Its 6-stage charging covers lithium-ion, LiFePO4, LTO, gel, AGM, flooded and calcium batteries.
An LCD shows battery voltage, charging current and charged amp-hours, and a port accepts an optional battery temperature sensor. The ABS case is rated IP65 with a conformal-coated circuit board, and Rich Solar lists the controller for RVs, trailers, campers, vans, boats and off-grid systems.
Charging runs through diagnose, soft start, bulk, absorption, equalization and float. On lithium settings, the diagnose stage checks the battery's starting voltage. If a BMS has shut the battery off, the controller periodically sends a signal to the battery terminals to reactivate it. Soft start ramps an over-discharged battery up to 10V at up to 5A, then bulk charges at the full rated current until the battery reaches absorption voltage.
Hold the BATTERY TYPE button for 3 seconds to choose lithium-ion, LiFePO4, LTO, gel, AGM, flooded (wet) or calcium. AGM is the default, and the controller remembers your choice. Absorption voltages at 77°F are 14.1V for gel, 14.4V for AGM and LiFePO4, 14.7V for flooded, 14.9V for calcium and 14.0V for LTO. Absorption ends when current falls to 1.5A or after 4 hours. Lead-acid batteries then float at 13.6V. LiFePO4 and LTO batteries have no float stage and return to bulk charging at 13.4V and 13.2V.
On the flooded and calcium settings, the controller runs a 15.5V equalization charge for 2 hours when the battery drops below 10V or every 28 days. LiFePO4, LTO, gel and AGM batteries skip this stage.
Press the VOLT/AMP button to step through battery voltage, charging current, charged capacity in amp-hours and battery temperature when a sensor is connected. The LCD can also serve as a voltmeter or thermometer on its own, and a reading below 11.5V means the battery needs charging. LEDs show battery condition and charging status.
A port on the controller accepts an optional battery temperature sensor (BTS). With the sensor connected, charging is compensated at -24mV/°C across -4°F to 122°F (-20°C to 50°C), and the LCD shows battery temperature.
The ABS plastic case is rated IP65, the circuit board is conformal coated against moisture, and the terminals are corrosion-resistant. Protection covers over-voltage, short circuit, reverse polarity and over-temperature, with charging protection at 149°F (65°C). The no-spark design helps prevent sparks when you connect the battery, and standby draw at night is 5mA. The spec sheet lists CE, FCC and RoHS certification.
RVs and travel trailers. Charge a 12V lithium or AGM battery from a small panel of up to 150W.
Boats. Keep a 12V marine battery charged, with an IP65 case and a coated circuit board.
Vans and campers. Check charging current and amp-hours at a glance on the LCD.
Small off-grid systems. Charge a 12V battery bank from a modest array, with the optional temperature sensor for temperature-compensated charging.
Rich Solar's shared spec sheet lists the same 12V system voltage, 25V open-circuit limit and IP65 rating for all three. The 10 handles 150W, the 20 handles 300W and the 30 handles 500W. The 10 and 20 share a 4.5 x 5.2 x 1.3 inch case, while the 30 measures 4.6 x 5.6 x 1.5 inches. Choose by the solar wattage you plan to connect, and leave room if you expect to add panels.
An MPPT controller converts extra panel voltage into charging current and is usually chosen for larger or higher-voltage arrays. The BRAVO Weatherproof 10 is a simpler PWM design for 12V-rated panels within its 15V to 22V recommended input range.
Keep the array within 10A and 150W, with an open-circuit voltage no higher than 25V. The manual says to always install a fuse on each circuit, including the solar controller; it doesn't list a fuse size for this model, so ask us if you need help choosing one. The power terminals take stranded wire up to #10 AWG, tightened to up to 17 in-lb.
This controller uses common positive grounding, so confirm it matches how your system is wired. Rich Solar specifies vertical wall mounting on a flat surface with the four supplied plastic spacers and self-tapping screws. Cover the panel before you connect cables. Once wiring is complete, the controller starts working automatically.
Yes. When a lithium battery is protected by its BMS, the controller automatically sends a signal to the battery terminals to reactivate it before charging.
No. The battery temperature sensor is optional and not included. Adding it lets the controller compensate charging voltage for battery temperature and display that temperature on the LCD.
It uses common positive grounding, and Rich Solar lists the grounding as positive ground.
The manual states a 2-year Rich Solar warranty. Faulty products claimed within that period are repaired or replaced free of charge with valid proof of purchase.
The Rich Solar BRAVO Weatherproof 10 combines 6-stage PWM charging, seven battery profiles, an LCD readout and an IP65-rated case for 12V systems up to 150W. If you have questions about panels, fuses or battery settings, the Outbound Power team is happy to help.
