Rich Solar RS-K390SL 390W Slim Solar Kit
The Rich Solar RS-K390SL 390W Slim Kit is a compact solar charging package built for camper vans, RVs, trailers, boats, cabins, sheds, and off-grid battery systems where roof space is limited. With three MEGA 130W Slim solar panels, a BRAVO 30A MPPT charge controller, mounting brackets, fuse protection, and included solar and battery cables, this kit gives customers a narrow-panel setup designed for cleaner installs in tighter spaces.
Product Overview
The RS-K390SL is designed for customers who want meaningful solar charging capacity but do not have the roof layout for wider standard panels. The slim panel format makes this kit especially useful for camper vans, RV roof edges, trailer roofs, boats, narrow mounting zones, and other spaces where panel width is a challenge.
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 controller. Customers will still need the right battery, inverter, breakers, and system design depending on what they want to power.
What Comes in the Kit
The RS-K390SL 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 narrow-format 130W panels create a 390W 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, a 10 ft 8AWG battery cable for controller-to-12V battery connection, one set of mounting Z brackets, and a 10A 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 vents, racks, roof curves, skylights, antennas, storage boxes, or narrow open areas. The long, narrow panel format makes the RS-K390SL a strong option for mobile and compact off-grid solar builds.
Key Features That Matter
This description keeps the focus on why customers choose a slim kit: panel fitment, clean installation, MPPT charging, included wiring parts, fuse protection, and better flexibility in real RV, van, boat, and off-grid layouts.
The MEGA 130W Slim 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.
Slim panels make it easier to work around roof vents, skylights, racks, antennas, and other obstacles. That helps customers use available roof space more efficiently instead of leaving narrow gaps unused.
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, mounting brackets, BRAVO 30A charge controller, and 10A fuse holder help reduce sourcing headaches and make the kit easier to plan around.
