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.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eFour 100W Slim Onyx Panels for Compact Solar Layouts\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003e400W Total Solar Capacity with MPPT Charging Support\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eY-Branch Adapters, 8AWG Battery Cable, and 15A Fuse Included\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThis kit includes additional connection components compared with smaller slim kits, including Y-branch parallel adapters and a 15A inline fuse holder.
