Powerwall 3
- Fixed storage capacity of 13.5kWh.
- Designed to work best in Tesla’s ecosystem but can also be integrated with non-Tesla solar systems.
- Best suited for single-phase homes, with limited support for three-phase setups and can only back up a single phase.
SigenStor
- Modular design with a starting capacity of 8kWh, expandable up to 48kWh per stack of six.
- Available in both single-phase and three-phase configurations, making it more flexible.
- Offers full three-phase backup, making it ideal for homes with large appliances that require balanced power distribution.
Powerwall 3 and SigenStor are strong home energy solutions but they serve different needs. Powerwall 3 is best for simple, all-in-one installations on single-phase homes, while SigenStor offers more flexibility, scalability, and backup power options for single or three-phase homes.
