The Rich Solar 400 Watt SLIM ONYX Solar Kit (RS-K400SL) is a 12V solar charging kit built around four 100W MEGA 100 SLIM ONYX panels (RS-M100SLB) and a BRAVO 30 30A MPPT charge controller with built-in Bluetooth. Rich Solar estimates that the 400W array produces approximately 1.4kWh of energy per day under 4 peak sun hours. The kit also includes a 30 foot 10 AWG solar cable set, a 10 foot 8 AWG battery cable, four sets of four Z brackets, a Y branch parallel adapter and a 15A inline fuse holder for the solar circuit.
Each panel is 15.8 inches wide and 50 inches long, so the four panels can be arranged around roof vents, fans and racks. Rich Solar builds its Slim Kits for RVs, vans, trailers, boats, tiny homes and other off-grid charging systems. You supply the 12V battery, since no battery or inverter is included.
Each MEGA 100 SLIM ONYX panel measures 50.0 x 15.8 x 1.2 inches (1270 x 400 x 30 mm) and weighs 12.4 lb (5.6 kg), and together the four panels make up the kit's 400W array. Rich Solar designed the slim profile to give you more placement options on compact rooftops. The ONYX panels are all black, including the frame.
Each panel uses 34 N-Type TOPCon cells (2 x 17), with up to 25.1% cell efficiency and 19.7% module efficiency. It's rated 100W with a 0 to +5W power tolerance, 5.10A at a maximum power voltage of 19.6V, and 23.6V open circuit. It has 3.2 mm AR-coated tempered glass, an anodized aluminum frame and an IP67 junction box, with mechanical strength certified to 5400 Pa positive and 2400 Pa negative load.
The BRAVO 30 tracks the array's maximum power point at 99.5% efficiency or better and converts it to charging power at up to 98% efficiency. Rich Solar rates it for a nominal 500W of solar at 12V and 1,000W at 24V, with up to 100V of open-circuit input and 30A of charging current, so this 400W array is within its rating. It detects a 12V or 24V battery automatically and guards against reverse polarity, short circuits, reverse current at night and overheating.
Built-in Bluetooth connects the BRAVO 30 to the RICH SOLAR app, so you can check charging from your phone. The LCD shows solar voltage, current, power and kWh plus battery voltage, charging current and charged amp-hours. A remote display and a battery temperature sensor are optional.
Presets cover LiFePO4 (LFP), LTO, LCO, lead crystal, Gel, AGM, flooded and calcium batteries, plus a custom setting for your battery maker's voltages. AGM is the default, so choose your battery type during setup. If a lithium battery's BMS has shut it off after a deep discharge, the controller tries to wake it automatically.
RVs and travel trailers. Fill the narrow spaces on a busy roof with four slim panels for 400 watts of charging.
Camper vans. Cover a long van roof with four panels that stay 15.8 inches wide.
Boats. Charge a larger 12V house bank from panels split to fit a hardtop or cabin roof.
A PWM controller is a simpler design, but it can't turn surplus panel voltage into extra charging current. The BRAVO 30 in this kit uses MPPT tracking instead, and it adds Bluetooth monitoring, an LCD and profiles for lithium and lead-acid batteries.
A wider panel of similar wattage can be hard to fit between roof vents, fans, hatches and racks. At 15.8 inches wide, the four slim panels fit narrow strips of roof.
Rich Solar's wiring drawing for this kit shows two pairs of panels, each pair wired in series, joined in parallel by the included Y branch adapter, with the 15A inline fuse on the combined positive lead. It also shows an optional 30A ANL fuse on the battery's positive cable, which isn't included. The BRAVO 30 manual strongly recommends an inline fuse on the positive wire of both the solar and battery circuits, and asks you to cover the panels before connecting cables. If you change the layout, keep the array's open-circuit voltage under the controller's 100V limit, rated at -4°F (-20°C).
Mount the BRAVO 30 indoors on a vertical surface, out of the weather and as close to the battery as possible. No battery or inverter is included, so plan for a 12V battery that suits your loads and select its type in the controller's settings.
No. You'll need your own 12V battery. Rich Solar's wiring diagram shows its ALPHA 2 12V 200Ah LiFePO4 battery and NOVA PURE 2K 12V inverter as examples, and both are marked not included.
Rich Solar estimates approximately 1.4kWh of energy per day under 4 peak sun hours. Days with fewer peak sun hours will produce less.
This kit already uses 400W of the BRAVO 30's nominal 500W rating at 12V, and the controller tops out at 30A of solar input current and 100V open circuit at -4°F (-20°C). Ask our team before you add panels so we can check the controller and wiring.
Rich Solar backs the MEGA 100 SLIM ONYX with a 25-year power output warranty and a 10-year limited workmanship warranty.
The Rich Solar 400 Watt SLIM ONYX Solar Kit combines four 100W MEGA 100 SLIM ONYX panels (RS-M100SLB), a BRAVO 30 MPPT controller with Bluetooth, and the cables, brackets and fuse holder that connect them to your 12V battery. If you'd like help choosing a battery or planning your roof layout, the Outbound Power team is happy to help.
