The Rich Solar BRAVO LEGEND 40 (RS-PWM40P) is a 40 amp PWM solar charge controller with 3-stage charging for 12V and 24V systems. It recognizes the system voltage automatically, or you can set it manually, and it is rated for 600W at 12V or 1,200W at 24V with solar input up to 55V.
Load terminals with five working modes, a dot-matrix LCD with two keys and a USB port make it a simple all-in-one controller for RVs, boats, off-grid systems, lighting and monitoring devices. It is ETL listed to UL 1741 and CSA C22.2 No. 107.1.
Charging runs through boost, float and equalization stages. Equalization helps prevent sulfation in lead-acid batteries; it runs every 30 days or after an over-discharge and is skipped for gel and lithium batteries. Boost lasts 2 hours and equalization 1 hour. Temperature compensation adjusts charging voltage by -3.0mV/°C per 2V cell, except for lithium.
Select flooded, sealed, gel or lithium. Sealed is the default. On a 12V system, boost voltage is 14.6V for flooded, 14.4V for sealed, 14.2V for gel and 14.4V for lithium, with float at 13.8V for the lead-acid types. You can adjust the lithium charging voltage and the over-discharge and recovery points (11.0V and 12.5V by default) with the keys. Voltages double on a 24V system.
Light control switches the load on after a 10-minute delay once it gets dark and off once sunlight returns. Light plus timer mode runs the load for 1 to 14 hours after dark. Manual mode lets you switch it with the keys, debugging mode (the default) switches it with panel voltage for quick testing, and normal-on mode keeps the load powered. An advanced start method lets loads with large capacitance start smoothly.
The LCD shows day or night, charging stage, battery status and load status, and steps through solar voltage and current, battery voltage, discharge current, charged and discharged amp-hours, controller temperature, load mode and error codes. A USB port charges small devices, and power-down memory keeps your settings after a power loss.
An RJ12 data port outputs TTL232-level or Bluetooth signals using the standard Modbus protocol. With the optional Bluetooth function, you can monitor the controller from a phone app.
Protection covers overcharge, over-discharge, overload, short circuit, reverse polarity and controller over-temperature, and TVS lightning protection guards against surges. A load at 1.25 times the rated current trips after 30 seconds, 1.5 times after 5 seconds and 2 times after 1 second, and the output recovers automatically after 1 minute.
RVs and campers. Charge a 12V house battery from up to 600W of panels.
Boats. Keep batteries charged with the controller mounted in a dry, ventilated spot.
Off-grid systems. Run up to 1,200W of solar into a 24V battery bank.
Lighting and monitoring. Use light control or timer modes for street lights and monitoring devices.
Both share 12V/24V auto detection, the 55V solar input limit, four battery types, load modes and a USB port. The BRAVO LEGEND 30 (RS-PWM30P) is rated 30A, with 450W at 12V or 900W at 24V. The BRAVO LEGEND 40 adds 10A of capacity for 600W at 12V or 1,200W at 24V.
An MPPT controller converts extra panel voltage into charging current, which helps when panels are wired in series. The BRAVO LEGEND 40 is a PWM controller with a 55V input limit, so it suits panels matched to the battery voltage and systems that also need built-in load control.
Connect the battery first; the screen lights up if the connection is correct. Then connect the solar panels, and finally the load, keeping load current within the controller's 40A rating. Rich Solar recommends a fuse in series with the battery. The controller has a common positive inside, so if your system needs grounding, ground the positive side. Use cables large enough that line losses don't cause the controller to misjudge battery voltage.
Mount the controller securely in a well-ventilated spot, since it produces heat during operation. It is rated IP30 and operates from -13°F to 131°F (-25°C to 55°C). Keep battery voltage under 34V and solar input under 55V. On a 24V system, panel terminal voltage can exceed safe touch levels, so use insulated tools and keep your hands dry.
Yes. Rich Solar lists positive grounding. The controller has a common positive inside, so ground the positive pole if your system needs a ground.
Bluetooth is optional. The RJ12 data port carries Bluetooth or TTL232-level signals for monitoring software or a phone app.
Yes. The lithium profile boosts to 14.4V on a 12V system by default, and you can adjust that point. Lithium batteries skip equalization and temperature compensation.
The controller itself won't be damaged, but the load terminals will output a negative voltage that could damage your devices. On a 24V system, reversing both the battery and the solar panels at once may damage the controller.
The Rich Solar BRAVO LEGEND 40 PWM Controller gives 12V and 24V systems 40 amps of 3-stage charging, five load modes, a USB port and UL 1741 certification. If you'd like help matching it to your panels, battery or loads, the Outbound Power team is happy to help.
