Rich Solar RS-K300SL 300W Slim Onyx Solar Kit

The Rich Solar RS-K300SL 300W Slim Kit is a compact solar charging package built for camper vans, RVs, trailers, boats, cabins, sheds, and small off-grid battery systems where roof space is limited. With three MEGA 100W SLIM Onyx solar panels, a BRAVO 30A MPPT charge controller, mounting brackets, fuse protection, and included solar and battery cables, this kit gives customers a clean black narrow-panel setup for smaller 12V battery charging builds.

300W Total solar panel capacity from three included 100W Slim Onyx solar panels.
3 Panels Long, narrow black panels designed for tight roof layouts and compact installs.
30A MPPT Included BRAVO 30A MPPT controller helps manage efficient battery charging.
Compact Built for vans, RVs, boats, and smaller off-grid setups where standard panels may not fit well.

Product Overview

The RS-K300SL is designed for customers who want a smaller slim-panel solar kit that can work around roof vents, racks, skylights, antennas, storage boxes, and narrow open spaces. The Slim Onyx panel format makes it especially useful for camper vans, RV roof edges, trailers, boats, small cabins, and compact off-grid battery charging systems.

This is a solar charging kit, not a complete power system. It is made to collect solar energy and charge a compatible 12V battery through the included MPPT charge controller. Customers will still need the correct battery, inverter, breakers, fuses, and system design depending on what they want to power.

What Comes in the Kit

The RS-K300SL bundles the core solar charging components needed to connect three slim solar panels to a compatible 12V battery setup. It includes panels, controller, wiring, brackets, and fuse protection so customers do not have to source every small part separately.

3 x MEGA 100W Slim Onyx Panels

Three black narrow-format 100W panels create a 300W solar array for space-conscious RV, van, marine, cabin, and off-grid charging setups. The slim shape helps fit roof edges, gaps, and layouts where wider panels may be difficult to install.

1 x BRAVO 30A MPPT Controller

The included 30A MPPT controller regulates solar charging from the panel array to the battery bank. MPPT charging helps improve solar harvest compared with basic PWM-style charging when installed with a compatible system.

Cables, Brackets & Fuse

The kit includes a 30 ft 10AWG solar cable set, 10 ft red and black #10 battery cables for controller-to-battery connection, one set of mounting Z brackets, and a 10A inline solar panel fuse holder.

Built for Slim Roof Layouts and Smaller Solar Builds

This kit is best for customers who want solar charging support but need panels that fit around real-world roof obstacles. The long, narrow Onyx panel format helps make better use of slim roof sections while keeping the overall install clean and low-profile.

Camper Vans & Overlanders A practical solar charging option for van roofs where fans, racks, vents, and narrow mounting spaces limit panel placement.
RVs & Travel Trailers Useful for RV roof edges, trailer roof gaps, and layouts where standard rectangular panels may take up too much width.
Boats & Marine Use A slim-panel option for compatible marine charging setups where mounting space can be narrow or awkward.
Cabins, Sheds & DIY Off-Grid Works for small off-grid builds that need a compact 12V solar charging foundation.

Key Features That Matter

This description keeps the focus on why customers choose a 300W Slim Onyx kit: compact fitment, clean black panel appearance, MPPT charging, included wiring parts, fuse protection, and better flexibility in real RV, van, boat, and off-grid layouts.

Slim Onyx Panels for Tight Roof Spaces

The MEGA 100W Slim Onyx panels are designed for long, narrow mounting areas where standard panels may not fit. This makes the kit especially useful for vans, RVs, trailers, boats, and compact off-grid installations.

Narrow, Low-Profile Panel Format

The Slim Onyx panel format helps customers use available roof space more efficiently. The long, narrow footprint is easier to plan around vents, skylights, racks, and other roof accessories than many wider panel layouts.

Battery Charging System Foundation

The kit is designed to charge a compatible 12V battery bank through the included MPPT controller. When paired with the right battery and inverter, it can become part of a complete RV, van, marine, cabin, or small off-grid power system.

Frequently Asked Questions

Clear answers to common questions about this product, setup, compatibility, and use.

What is in the box when I order the 300W Slim Kit? The official package list specifies: 3x MEGA 100W SLIM Onyx Solar Panel; 1 x 30' 10AWG Solar Cable Set (Panel to Controller); 1 x 10' #10 Gauge Battery Cable (Red), connects controller to battery; 1 x 10' #10 Gauge Battery Cable (Black), connects controller to battery; 1 x Bravo 30A MPPT Charge Controller; 1 x Mounting Z Brackets (one set); 1 x 10A Solar Panel Inline Fuse Holder. Equipment shown elsewhere in photos should not be treated as included unless it appears in that manufacturer list. Which solar panels make up the array in the 300W Slim Kit? The array hardware is listed as 3x MEGA 100W SLIM Onyx Solar Panel (RS-M100SLB). Use those exact module electrical ratings when planning strings, controller inputs, mounting area, roof or ground loading, and future expansion. The advertised kit wattage does not replace a series-parallel voltage and current check. Which battery equipment is supplied with the 300W Slim Kit? No battery appears in the official kit-contents list. A compatible bank must be selected separately for the system voltage and must support the controller or inverter's charging current, continuous load, startup surge, BMS requirements, cabling, fuse, and disconnect design. What inverter hardware comes with the 300W Slim Kit? No inverter appears in the official package list, so this kit does not create household AC power by itself. Add an inverter whose battery voltage, continuous output, startup surge, waveform, cabling, fuse, and disconnect requirements match the planned battery bank and loads. How is battery charging regulated in the 300W Slim Kit? The charge-control equipment is listed as 1 x Bravo 30A MPPT Charge Controller (RS-MPPT30PB). Before changing the supplied panel layout or expanding later, verify the controller's maximum PV open-circuit voltage, tracking range, input current, charge-current limit, supported battery voltage, and battery profiles. Beyond its slim modules and packaged wiring, what must be designed for the 300W Slim Kit? The remaining listed balance-of-system items are 1 x 30' 10AWG Solar Cable Set (Panel to Controller) (RS-30101); 1 x 10' #10 Gauge Battery Cable (Red), connects controller to battery (RS-1010); 1 x 10' #10 Gauge Battery Cable (Black), connects controller to battery (RS-1010); 1 x Mounting Z Brackets (one set) (RS-ZB4C); 1 x 10A Solar Panel Inline Fuse Holder (RS-SC10F). The site can still require structure-specific mounting, conduit or cable protection, grounding and bonding, code-required disconnects and overcurrent protection, distribution equipment, permits, inspection, and labor. Confirm the final one-line design rather than assuming the word "complete" covers every site condition.
