It’s great that you’ve already narrowed down your daily consumption to 1500Wh, as that’s the most important first step.
Regarding the Renogy kit, a 600W system is a solid starting point for those needs, but keep in mind that "600 watts per hour" is a bit optimistic due to weather, shading, and conversion losses. In reality, you might get about 4–5 hours of peak sun depending on your location, so you'll likely produce just enough to cover your usage and top off the batteries.
