Our verdict
The DELTA 3 with a $100 premium for smart-home integration and faster UPS switching. Same battery, same surge.
Best for: Home-office setups where a desktop or NAS can't tolerate a power blip.
What we like
- Identical 3600W surge and 4000 cycles
- Sub-10ms UPS switching for sensitive electronics
- Expandable to 5kWh
Where it falls short
- $100 more for features many buyers never use
- Same 1024Wh as the cheaper DELTA 3
