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.
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.
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.
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.
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.
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.
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.
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.
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.
The included solar cable, battery cables, mounting brackets, BRAVO 30A charge controller, and 10A fuse holder help reduce sourcing headaches and make the kit easier to plan around.
