When homeowners decide to enhance the resilience of their home with battery storage, they often face a challenging choice: which electrical loads should be backed up during a power outage? Despite the considerable progress made in battery technology, storage systems have limited capacity to provide uninterrupted power for the entire home during extended outages.

By using the Span Home App, the priority of circuits that need backup can be modified in real-time during power outages. When the battery runs low, non-essential loads will automatically shut down, freeing up more capacity for critical loads. Moreover, Span offers transparency to homeowners by providing an estimated remaining time for backup power, based on their load priorities, battery capacity, and past usage trends within the home.
