Rich Solar RS-K390SL 390W Slim Solar Kit – Triple 130W MPPT Charging Package

The Rich Solar RS-K390SL 390W 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 130W Slim Solar Panels, a Bravo 30A MPPT charge controller, a 30' 10AWG solar cable set, a 10' 8AWG battery cable, mounting Z brackets, and a 10A inline fuse holder. Together, the three included panels provide 390W 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 recommended solar power capacity of 500W at 12V or 1000W at 24V. 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 130W Slim Panels for Higher Compact Output

The RS-K390SL includes three MEGA 130W Slim Solar 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 may fit better than wider modules.

390W Total Solar Capacity with MPPT Charging Support

The three-panel package provides 390W 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.

8AWG Battery Cable, Solar Cable, Brackets, and Fuse Included

This kit includes the primary connection and mounting components needed to begin planning a small solar charging setup. The included 30' 10AWG solar cable set, 10' 8AWG battery cable, 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-K390SL 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 390W Slim Solar Kit with three 130W narrow panels for compact off-grid charging

The triple 130W 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, 10AWG solar cable set, 8AWG battery cable, brackets, and fuse holder help support a cleaner starting point for a properly planned solar battery charging installation.
