Frequently Bought Together
BRAVO 50 — 50A MPPT Solar Charge Controller
The BRAVO 50 is a 50-amp MPPT charge controller with true MPPT tracking efficiency above 99.5% and charge conversion efficiency as high as 98%. Designed and manufactured in-house, it automatically self-adapts to 12V or 24V systems and supports common negative connection wiring, onboard charging data storage, and a conformal-coated internal board — a feature-rich controller built for off-grid systems that need genuine charging efficiency and a flexible, accurate protection set.
True MPPT, 99.5%+ Tracking Efficiency
Genuine MPPT charging tracks the array's maximum power point with tracking efficiency above 99.5% and charge conversion efficiency as high as 98%, supporting a recommended PV input of 700W at 12V or 1400W at 24V across a 100V maximum open circuit voltage.
Common Negative Connection Support
Supports a common negative wiring configuration, a topology requirement for certain inverter and system setups — giving you flexibility in how the controller integrates into a larger electrical design.
Onboard Charging Data Storage
Stores charging data directly on the controller, giving you a historical record of system performance without needing a separate logging device.
Product Overview
The BRAVO 50 is a 50A MPPT (Maximum Power Point Tracking) solar charge controller engineered and manufactured by Rich Solar to deliver genuine, accurate charging performance for off-grid 12V or 24V systems. True MPPT tracking — rated above 99.5% efficiency — combined with charge conversion efficiency as high as 98% means more of your array's available power actually reaches the battery bank, particularly valuable with higher-voltage panel strings or in variable light conditions throughout the day. The controller accepts up to 100V DC maximum PV open circuit voltage and supports a recommended PV input power of 700W at 12V or 1400W at 24V.
The controller automatically self-adapts to 12V or 24V systems without requiring manual configuration, and supports common negative connection wiring — a topology consideration relevant to certain inverter and system integration setups. Reverse discharge protection and overvoltage protection are described as targeted for accuracy, providing reliable safeguards on both the panel and battery sides of the circuit. The internal board carries conformal coating, an added layer of protection against moisture and contamination for the electronics housed inside. Onboard charging data storage records system performance history directly on the controller, giving you a usable record of how your array and battery have performed over time.
Battery type selection is genuinely broad, covering lead-acid presets (GEL, AGM, WET, Crystal, Calcium) and lithium presets (LiFePO4, LTO, LCO) — a wide enough range to suit most battery chemistries used in off-grid, RV, marine, and cabin installations. The housing's IP rating is split by component: IP43 for the internal PCBA and IP22 for the connection area, meaning the internal electronics carry meaningfully more protection than the exposed terminal connections — worth factoring into your mounting location and wiring approach. At 7.7 × 5.5 × 2.9 in and 3.09 lb, the BRAVO 50 is a compact, manageable unit to mount in most installation spaces.
Maximizing Harvest From Your Array
