Rich Solar 50 Amp DC to DC Lithium Battery Alternator Charger with MPPT

The Rich Solar 50 Amp DC to DC Lithium Battery Alternator Charger With MPPT Charges Your House Battery From the Alternator and Solar at Once

The Rich Solar 50 Amp DC to DC Lithium Battery Alternator Charger With MPPT, sold by Rich Solar as the BRAVO 50 DC (RS-MPPT50DC), combines a DC-DC alternator charger and an MPPT solar charge controller in one unit. It delivers up to 50A of charging current to a 12V house battery from your vehicle's alternator, your solar panels, or both at the same time.

The alternator input works with conventional and smart 12V or 24V alternators at up to 65A, and the solar input accepts up to 55V with up to 800W of recommended PV. Built-in Bluetooth connects to the RICH SOLAR app, and RS485, CAN (RV-C) and TTL ports allow integration with other system components in RVs, vans, trailers and boats.

Rich Solar 50 Amp DC to DC Lithium Battery Alternator Charger With MPPT Features

Dual-Source Charging

The BRAVO 50 DC charges from solar and the vehicle alternator simultaneously or independently. Selectable charging priority lets you favor solar or alternator charging to match how you drive and camp.

MPPT Solar Charging

Rich Solar's PowerCatcher MPPT technology delivers over 99% tracking efficiency. The solar input accepts up to 55V DC and 50A, with an MPPT range of 17V to 36V and up to 800W of recommended solar.

Smart and Traditional Alternator Support

The alternator input works with conventional and smart alternators on 12V or 24V vehicles, at up to 65A. Buck/boost charging delivers the right voltage to the house battery even when the alternator voltage varies.

Lithium and Lead-Acid Profiles

The charger supports flooded, AGM, GEL, calcium and LiFePO4 batteries on a 12V battery system, with a 9V to 16V operating range and up to 96% conversion efficiency.

Bluetooth and System Communication

Monitor and configure the charger through the RICH SOLAR app over built-in Bluetooth. RS485, CAN with the RV-C protocol and TTL interfaces support integration with compatible monitoring and control systems.

Built for Mobile Systems

Electronic protection guards against over-temperature, overcharge, overcurrent, reverse polarity and short circuit. The operating range of -31°F to 149°F (-35°C to 65°C) suits cargo areas and storage compartments in hot and cold climates.

Real-World Applications

Camper vans. Charge a lithium house battery while you drive and from roof solar while you are parked.

Truck campers and overland rigs. Keep a 12V house battery full on long drives, even with a smart alternator.

Travel trailers and fifth wheels. Charge the trailer battery from the tow vehicle and from trailer-mounted panels.

24V trucks with 12V house systems. Use the 24V-compatible alternator input to charge a 12V battery.

Boats. Charge a house bank from the engine alternator and deck solar together.

How It Compares to Common Alternatives

Versus a battery isolator or relay. An isolator simply connects the batteries, so a lithium house battery may undercharge or overload the alternator. A DC-DC charger controls the charge profile and current for the house battery.

Versus a separate DC-DC charger and solar controller. Two separate units mean more wiring and two devices to configure. The BRAVO 50 DC handles both sources in one box with one app.

Versus a solar-only controller like the BRAVO 30. A solar-only controller charges only when the sun is out. The BRAVO 50 DC adds alternator charging for cloudy days and long drives.

Is This Charger the Right Fit

• House battery. The BRAVO 50 DC charges 12V battery systems only, with a 9V to 16V range.
• Vehicle. It works with 12V or 24V conventional and smart alternators, drawing up to 65A from the alternator side.
• Solar array. Stay within 55V and 50A of solar input, and up to 800W recommended. The MPPT range is 17V to 36V.
• Location. The IP32 rating calls for a dry, protected spot. The unit measures 8.70 x 6.92 x 3.64 inches and weighs 5.16 pounds.

This may be a good fit if

• You want to charge a 12V lithium house battery while driving
• Your vehicle has a smart alternator
• You also have or plan roof solar up to 800W
• You want one charger for both sources with app monitoring
