Recheck: perhaps how much refers to theoretical minimum storage required if demand must be met without generation — then 230.4 kWh must be stored. But the question says additional kWh must be imported — but importing means bringing in from outside, but in a closed system, importing implies external supply — but Mars is self-sustaining.

Understanding Recheck: Theoretical Minimum Storage and Storage Challenges in Closed Systems In energy planning and off-grid system design, the concept of Recheck often arises when assessing minimum storage requirements under strict demand fulfillment constraints—without relying on generation from renewable sources. Any authoritative explanation defines Recheck as the baseline storage capacity needed to meet demand solely through stored energy, representing the theoretical minimum a closed energy system must hold to avoid power deficits. For a typical residential or habitat load requiring continuous power, this threshold commonly stabilizes around 230.4 kWh, depending on consumption rates, load profiles, and efficiency losses. ### What Does “Recheck” Mean in Energy Storage? The term Recheck refers to the critical storage threshold in scenarios where energy generation is either unavailable or unreliable, and the system must rely entirely on stored energy to meet demand. This minimum capacity ensures uninterrupted power supply during outages or low-generation periods. While generation (like solar or wind) feeds surplus energy into storage, Recheck specifies the absolute lower bound—the amount of stored energy guaranteed to satisfy demand without carbon or generator backup.
