What should stay on when the power goes out?
Choose the loads that matter, set the outage length and build a practical plan around the battery you already have—or are considering.

How this is estimated
Each selected load uses its listed watts for its listed daily hours, scaled to your outage length. Usable battery energy = capacity × (1 − reserve) × efficiency. Solar help uses panel watts × useful sun hours × a 75% planning yield. The model does not simulate startup surges, thermostat cycles, weather or charging taper.
A plan beats a guess.
Keep critical loads small, leave reserve for uncertainty and test your actual appliances before an emergency. Never connect a portable station to home wiring unless a qualified electrician and the product manual allow it.
