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.

390W Total solar panel capacity from three included 130W Slim solar panels.
3 Panels Long, narrow MEGA 130W Slim panels designed for tight roof and mounting spaces.
30A MPPT Included BRAVO 30A MPPT controller helps manage efficient battery charging.
Slim Fit Built for vans, RVs, boats, and compact off-grid setups where standard panels may not fit well.

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.

3 x MEGA 130W Slim Panels

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.

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, 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.

Camper Vans 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 & DIY Off-Grid Works for sheds, cabins, and 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 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.

Slim Panels for Tight Install Spaces

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.

Cleaner Roof Layout Flexibility

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.

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 off-grid power system.

Frequently Asked Questions

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

Which panels, electronics, and wiring are included with the 390W Slim Kit? The official package list specifies: 3x MEGA 130W Slim Solar Panel; 1 x 30' 10AWG Solar Cable Set (Panel to Controller); 1x 10' 8AWG Battery Cable (Controller to 12V 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. What physical panel configuration comes with the 390W Slim Kit? The array hardware is listed as 3x MEGA 130W Slim Solar Panel (RS-M130SL). 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. Does the 390W Slim Kit include energy storage, or must I add a battery bank? 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. Does the 390W Slim Kit include AC power conversion, and at what listed configuration? 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. What solar-controller hardware is packaged with the 390W 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. Which balance-of-system decisions are still specific to a 390W Slim Kit installation? The remaining listed balance-of-system items are 1 x 30' 10AWG Solar Cable Set (Panel to Controller) (RS-30101); 1x 10' 8AWG Battery Cable (Controller to 12V Battery) (RS-810); 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.
