Rich Solar RS-K400SL 400W Slim Solar Kit – Four-Panel MPPT Charging Package

The Rich Solar RS-K400SL 400W Slim Solar Kit is a compact four-panel solar charging package for vans, recreational vehicles, boats, trailers, and small off-grid battery systems where narrow panel placement matters. This kit includes four MEGA 100W SLIM Onyx solar panels, a Bravo 30A MPPT charge controller, a 30' 10AWG solar cable set, Y-branch parallel adapters, a 10' 8AWG battery cable, mounting Z brackets, and a 15A inline fuse holder. Together, the four included panels provide 400W 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.

Four 100W Slim Onyx Panels for Compact Solar Layouts

The RS-K400SL includes four MEGA 100W SLIM Onyx panels, giving builders higher 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.

400W Total Solar Capacity with MPPT Charging Support

The four-panel package provides 400W 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.

Y-Branch Adapters, 8AWG Battery Cable, and 15A Fuse Included

This kit includes additional connection components compared with smaller slim kits, including Y-branch parallel adapters and a 15A inline fuse holder. The 30' 10AWG solar cable set, 10' 8AWG battery cable, mounting Z bracket set, and included connection hardware support a more complete starting point for a properly planned solar charging setup.

Compact Solar Support for Mobile and Off-Grid Builds

The RS-K400SL 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.

The four-panel slim 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, Y-branch adapters, 8AWG battery cable, solar cable, brackets, and 15A inline fuse holder help support a cleaner starting point for a properly planned charging installation.
