Battery Backup for Hawaii Homes on Oahu and Big Island

Why Hawaii Homeowners Are Adding Battery Storage to Their Solar Systems

Power outages are becoming more common in Hawaii, and energy costs keep rising. Solar with battery storage gives you control by storing energy for when you need it most, whether that’s at night, during peak utility rates, or when the grid goes down.

Pair your solar system with battery storage to keep your home running during outages, reduce your reliance on the grid, and protect yourself from unpredictable energy costs. With the ability to power essential loads or even your entire Hawaii home, home energy storage is designed for real-world reliability.

Be prepared when the grid isn’t
From unexpected blackouts to planned shutoffs, losing power is no longer rare. With battery storage, your home automatically switches to stored energy, keeping the lights on, appliances running, and your home comfortable without interruption.
