The Rich Solar 520 Watt SLIM Solar Kit (RS-K520SL) is a 12V solar charging kit built around four 130W MEGA 130 SLIM panels (RS-M130SL) and a BRAVO 40 40A MPPT charge controller with built-in Bluetooth. Rich Solar estimates that the 520W array produces approximately 1.9kWh 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 20A inline fuse holder for the solar circuit.
Each panel is 15.8 inches wide and 65 inches long, so the four panels suit long, narrow roofs with room for a larger array. 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 130 SLIM panel measures 65.0 x 15.8 x 1.2 inches (1650 x 400 x 30 mm) and weighs 15.4 lb (7 kg), and together the four panels make up the kit's 520W array. Rich Solar designed the slim profile to give you more placement options on compact rooftops. The MEGA 130 SLIM has a silver aluminum frame around its dark cells.
Each panel uses 34 N-Type TOPCon cells (2 x 17), with up to 25.3% cell efficiency and 19.8% module efficiency. It's rated 130W with a 0 to +5W power tolerance, 6.63A 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 40 tracks the array's maximum power point at better than 99.5% efficiency and converts it to charging power at up to 98% efficiency. Rich Solar recommends up to 600W of solar at 12V and 1,200W at 24V, with up to 100V of open-circuit input and 40A of charging current, so this 520W array is within its rating. It detects a 12V or 24V battery automatically and guards against over-charging, short circuits, reverse polarity and overheating.
The BRAVO 40 has a built-in Bluetooth module, a large LCD that shows real-time solar input, battery status and system settings, and an LED bar for charging status. It also stores charging data. The controller has ports for a remote display and an optional external battery temperature sensor.
Presets cover Gel, AGM, flooded, crystal and calcium lead-acid batteries and LiFePO4, LTO and LCO lithium batteries, plus a custom setting for your battery maker's voltages. AGM is the default, so choose your battery type during setup. Rich Solar also builds in a recovery and restart function for deeply discharged batteries.
RVs and fifth wheels. Line up four long, narrow panels for 520 watts of charging on a larger roof.
Camper vans and trucks. Cover a long roof with four slim panels and feed a larger 12V lithium bank.
Boats. Charge a 12V house bank from four panels sized to 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 40 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 20A inline fuse on the combined positive lead. It also shows an optional 40A ANL fuse on the battery's positive cable, which isn't included. The BRAVO 40 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 -20°C.
Mount the BRAVO 40 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 1.9kWh of energy per day under 4 peak sun hours. Days with fewer peak sun hours will produce less.
This kit already uses 520W of the BRAVO 40's recommended 600W at 12V, and the controller tops out at 40A of solar input current and 100V open circuit at -20°C. Ask our team before you add panels so we can check the controller and wiring.
Rich Solar backs the MEGA 130 SLIM with a 25-year power output warranty and a 10-year limited workmanship warranty.
The Rich Solar 520 Watt SLIM Solar Kit combines four 130W MEGA 130 SLIM panels (RS-M130SL), a BRAVO 40 MPPT controller with Bluetooth, and the cables, brackets and fuse holder that connect them to your 12V battery.
