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.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eThree 130W Slim Panels for Higher Compact Output\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe RS-K390SL includes three MEGA 130W Slim Solar Panels, giving builders more rated solar capacity while keeping each panel narrow and easier to position.
