Base Power has introduced Core, a large home battery system designed to deliver far more backup power than many residential units on the market. The company says the new battery offers 39.2 kWh of capacity, enough to keep a home running for as long as 36 hours, while also aiming for installation in under an hour.
The product launch comes alongside a major funding milestone. Base Power has raised $1 billion to support a broader rollout of the Core system to homes across the United States, signaling an aggressive push to expand its presence in the residential energy storage market.
A battery of this size is notable because homeowners are increasingly looking for longer-lasting backup during outages, not just short-term power for a few essentials. Systems with higher capacity can appeal to households that want more resilience, especially as interest grows in home energy independence and protection from grid disruptions.
With the debut of Core and a sizable capital raise behind it, Base Power is positioning itself to move quickly in a competitive sector. The combination of a high-capacity battery, a fast-installation pitch, and fresh funding could make the company one to watch as US demand for home backup power continues to grow.
