If maintaining power during a blackout is your priority, understanding how these battery systems provide backup power is crucial.
Some systems offer whole-home backup, while others are limited to only critical circuits, impacting how much of your home remains powered.
Powerwall 3 Backup Power
- Designed primarily for single-phase homes.
- If installed in a three-phase home, it can only back up one of the three phases.
- If installed on a three-phase home, the phases will remain unbalanced and require additional inverters at an additional cost.
SigenStor Backup Power
- Available in single-phase or three-phase configurations.
- Full three-phase backup, meaning it can keep all circuits running during an outage.
- Can integrate with generators, making it useful for homes that experience frequent blackouts.
If you have a three-phase home and need full backup power, SigenStor is the better option.
