Open RV campsite (clear sky, trees in the distance), a realistic 30-40-year-old Latino man takes the inverter out of the package (30-degree side angle, consistent color on front/back/side, size close to 46.2cm×35.6cm×16.8cm, no size deviation, no color modification); split screen shows 3 function icons (inverter, solar panel, battery charger), switching with product shots; the man demonstrates starting the product, the indicator light turns on, he makes a gesture to the inverter and the battery next to it (no wires connected), and shows a satisfied expression. American English narration, smooth shot transitions.
