Rich Solar RS-K400SL 400W Slim Onyx Solar Kit
The Rich Solar RS-K400SL 400W Slim Onyx Kit is a compact solar charging package built for camper vans, RVs, trailers, boats, cabins, sheds, overlanders, and off-grid battery systems where roof space is tight. With four MEGA 100W SLIM Onyx solar panels, a BRAVO 30A MPPT charge controller, Y-branch parallel adapters, mounting brackets, fuse protection, and included solar and battery cables, this kit gives customers a clean black slim-panel setup for space-limited 12V solar charging builds.
Product Overview
The RS-K400SL is designed for customers who want a sleek, narrow solar panel kit that can work around vents, roof racks, skylights, antennas, storage boxes, and awkward roof layouts. The Slim Onyx panel format makes it especially useful for camper vans, overlanders, RV roof edges, trailers, boats, and compact off-grid installs.
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-K400SL bundles the core solar charging components needed to connect four slim solar panels to a compatible 12V battery setup. It includes panels, controller, wiring, adapters, brackets, and fuse protection so customers do not have to source every small part separately.
Four black narrow-format 100W panels create a 400W 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. It supports 12V/24V auto-detection, high MPPT tracking efficiency, battery compatibility options, and real-time display monitoring.
The kit includes a 30 ft 10AWG solar cable set, Y-branch parallel adapters, a 10 ft 8AWG battery cable for controller-to-12V battery connection, one set of mounting Z brackets, and a 15A inline solar panel fuse holder.
Built for Slim Roof Layouts and Space-Limited Installs
This kit is best for customers who want useful solar charging capacity 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 Slim Onyx kit: tight-space fitment, 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 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 off-grid power system.
The included solar cable, 8AWG battery cable, Y-branch adapters, mounting brackets, BRAVO 30A charge controller, and 15A fuse holder help reduce sourcing headaches and make the kit easier to plan around.
