This kit includes four MEGA 130W Slim Solar Panels, a 40A MPPT charge controller, a 30' 10AWG solar cable set, Y-branch parallel adapters, a 10' 8AWG battery cable, mounting Z brackets, and a 20A inline fuse holder. Together, the four included panels provide 520W total rated solar capacity before real-world losses from shade, weather, panel angle, wiring, and installation conditions. The included 40A MPPT controller supports 12V and 24V auto-detect operation for compatible battery charging systems. 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 130W Slim Panels for Higher Compact Output\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe RS-K520SL includes four MEGA 130W Slim Solar Panels, giving builders the highest rated panel capacity in this slim-kit group 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\u003e520W Total Solar Capacity with 40A MPPT Charging Support\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe four-panel package provides 520W total rated solar output under standard test conditions. The included 40A 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 20A Fuse Included\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThis kit includes additional connection components for the larger slim-panel package, including Y-branch parallel adapters and a 20A inline fuse holder.
