Rich Solar RS-K300SL 300W Slim Solar Kit – Triple-Panel MPPT Charging Package

The Rich Solar RS-K300SL 300W Slim Solar Kit is a compact triple-panel solar charging package for vans, recreational vehicles, boats, trailers, and small off-grid battery systems where narrow panel placement matters. This kit includes three MEGA 100W SLIM Onyx solar panels, a Bravo 30A MPPT charge controller, solar and battery cables, mounting Z brackets, and a 10A inline fuse holder. Together, the three included panels provide 300W total rated solar capacity before real-world losses from shade, weather, panel angle, wiring, and installation conditions. The included MPPT controller supports 12V and 24V auto-detect operation and is listed with a recommended solar power capacity above this kit’s 300W panel total. Battery selection, mounting layout, wiring configuration, overcurrent protection, and final installation should be confirmed against current Rich Solar documentation and the needs of the complete electrical system.

Three 100W Slim Onyx Panels for Flexible Layouts

The RS-K300SL includes three MEGA 100W SLIM Onyx panels, giving builders more rated solar capacity while keeping each panel narrow and easier to position. This format is useful for compact roof plans where multiple slim panels can fit better than wider modules.

300W Total Solar Capacity with MPPT Charging Support

The three-panel package provides 300W total rated solar output under standard test conditions. The Bravo 30A MPPT controller helps manage charging for compatible 12V and 24V battery systems, with final output depending on sunlight, shade, wiring, battery setup, and installation quality.

Included Cables, Brackets, and Inline Fuse Holder

This kit includes primary connection and mounting components for planning a small solar charging setup. The 30' 10AWG solar cable set, 10' red and black battery cables, mounting Z bracket set, and 10A inline fuse holder help create a more complete starting package.

Compact Solar Support for Mobile and Off-Grid Builds

The RS-K300SL is best suited for supplemental charging and properly sized battery-based systems, not large appliance loads or full-property backup. Real-world usefulness depends on panel placement, charge settings, battery capacity, wire sizing, sun exposure, and daily energy demand.

Rich Solar 300W Slim Solar Kit with three 100W Onyx panels for compact off-grid charging

The triple slim-panel layout gives builders more charging potential while preserving narrow panel placement. It is a practical fit for mobile and small off-grid layouts where usable mounting space is limited.

The included MPPT controller, cables, brackets, and fuse holder help support a cleaner starting point for a properly planned solar battery charging installation.
