The Rich Solar BRAVO Weatherproof 30 (model RS-PWM30WP) is the 30 amp member of Rich Solar's IP65-rated PWM line for 12V battery systems. It accepts up to 30A and 500W of solar, with a recommended input of 15V to 22V and a 25V open-circuit limit, and charges LiFePO4, LTO, gel, AGM, flooded and calcium batteries through a 6-stage routine.
An LCD shows battery voltage, charging current and charged amp-hours, and a port accepts an optional battery temperature sensor. The ABS case has a conformal-coated circuit board, and four M5 ring terminals come in the box. Rich Solar lists it for RVs, trailers, campers, vans, boats and off-grid systems.
Charging moves through diagnose, soft start, bulk, absorption, equalization and float. On lithium settings, the diagnose stage reads the battery's starting voltage, and if a BMS has shut the battery off, the controller periodically signals the terminals to reactivate it. Soft start ramps an over-discharged battery up to 10V at up to 15A, then bulk charging runs at the full rated current until absorption voltage is reached.
Hold the BATTERY TYPE button for 3 seconds to choose 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, and LiFePO4 and LTO batteries return to bulk charging at 13.4V and 13.2V.
On the flooded and calcium settings, a 15.5V equalization charge runs for 2 hours when the battery drops below 10V, and every 28 days. LiFePO4, LTO, gel and AGM batteries skip this stage.
Press VOLT/AMP to cycle the LCD through battery voltage, charging current, charged capacity in amp-hours and battery temperature when a sensor is connected. The LCD also works as a standalone voltmeter or thermometer; below 11.5V, the battery needs charging. LEDs show battery condition and charging status.
Plug in an optional battery temperature sensor (BTS) and the controller compensates charging voltage at -24mV/°C across -4°F to 122°F (-20°C to 50°C), with battery temperature shown on the LCD.
The case is rated IP65, the circuit board is conformal coated against moisture and the terminals resist corrosion. Protection covers over-voltage, short circuit, reverse polarity and over-temperature, with charging protection at 149°F (65°C), and the manual lists a varistor or TVS at the input and output against surge voltage. The no-spark design helps prevent sparks at the battery connection, and standby draw at night is 5mA. The spec sheet lists CE, FCC and RoHS certification.
RVs and travel trailers. Charge a 12V house battery bank from roof panels totaling up to 500W.
Boats. Keep 12V marine batteries charged with an IP65-rated controller and a coated circuit board.
Vans and campers. Track charging current and amp-hours on the LCD.
Off-grid systems. Charge a 12V LiFePO4 or lead-acid bank, with temperature-compensated charging when you add the optional sensor.
Rich Solar's shared spec sheet gives all three the same 12V system voltage, 25V open-circuit limit and IP65 rating. The 10 handles 150W, the 20 handles 300W and this 30 handles 500W. The 30 is slightly larger at 4.6 x 5.6 x 1.5 inches, compared with 4.5 x 5.2 x 1.3 inches for the 10 and 20.
An MPPT controller converts extra panel voltage into charging current and is usually chosen for larger or higher-voltage arrays. The BRAVO Weatherproof 30 is a simpler PWM design for 12V-rated panels within its 15V to 22V recommended input range.
Keep the array within 30A and 500W, with an open-circuit voltage no higher than 25V. The manual's wiring diagram shows a 40A fuse on both the solar and battery circuits, and the spec sheet gives 40A as the example fuse for the 30A model. For one-way runs under 10 feet, the manual's cable chart calls for 10 AWG. It lists 8 AWG for 10 to 20 feet and 6 AWG for 20 to 30 feet, but the terminals are rated for stranded wire up to #10 AWG, so plan a short run or ask us how to handle a longer one. Tighten the terminals to up to 17 in-lb (1.92 N·m).
This controller uses common positive grounding, so check that it matches your system. Rich Solar specifies vertical wall mounting on a flat surface with the four supplied plastic spacers and self-tapping screws. Cover the solar panel before you connect cables. The controller starts working automatically when the connections are complete.
The manual's wiring diagram shows a 40A fuse on the solar circuit and another 40A fuse on the battery circuit, and the spec sheet gives 40A as the example for this 30A model.
Yes. On a lithium setting, the controller automatically sends a signal to the battery terminals to reactivate a battery that its BMS has protected.
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 30 brings 6-stage PWM charging, six battery profiles, an LCD readout and an IP65-rated case to 12V systems with up to 500W of solar. If you'd like help with fuses, cable runs or battery settings, the Outbound Power team is happy to help.
