Fortress Power

About

Fortress Power home battery backup systems, built around lithium battery storage for grid-outage backup and solar energy storage. These systems are designed to integrate with a home's electrical panel for whole-home or partial-home backup, rather than functioning as a portable power station — installation typically requires an electrician. Battery capacity should be sized around which circuits you actually want to keep running during an outage, not your home's total electrical load, since backing up everything usually isn't necessary or cost-effective.
