Editorial verdict

The top of the line: more capacity (4096 Wh) and more expandable (up to 48 kWh) than the DELTA Pro.

Best use case

A household that wants the maximum possible backup during long power outages and is willing to manage shipping for a large, heavy unit.

It's a full step above the DELTA Pro: more capacity (4096 Wh vs 3600 Wh), more output (4000W vs 3600W, up to 6000W with X-Boost), and expandable up to 48 kWh — double the DELTA Pro's ceiling. The manufacturer estimates 2-4 days of whole-house backup with the base unit.

At 52 kg, it's the most complex international shipping logistics in the entire catalog.

Pros

  • The biggest backup in the catalog: 4096 Wh, expandable up to 48 kWh
  • 10ms battery switchover — works as a true UPS
  • Very quiet (30 dB)
  • 5-year factory warranty

Cons

  • 52 kg: the most complex international shipping logistics in the entire catalog

Ideal for: A household that wants the maximum possible backup during long power outages and is willing to manage shipping for a large, heavy unit.
