Editorial verdict

Nearly as much power as the DELTA Pro (3600W continuous, up to 7200W peak), with a panel included and a battery switchover under 10ms.

Best use case

Anyone looking for nearly the same power as the DELTA Pro, with a solar panel included in the same order.

It sits just below the DELTA Pro in capacity (3072 Wh vs 3600 Wh) but matches its continuous output (3600W) and beats it on peak (7200W). Switches to battery in under 10 milliseconds — works as a true UPS — and is the quietest in the catalog, 25dB under load.

Includes a 400W solar panel in the same order. Given the similar power to the DELTA Pro, it's worth comparing the two before choosing.

Pros

  • Nearly the same power as the DELTA Pro, with a solar panel included
  • Battery switchover under 10ms — true UPS
  • The quietest in the catalog (25dB)
  • 5-year warranty

Cons

  • This listing doesn't confirm whether it supports an extra battery

Ideal for: Anyone looking for nearly the same power as the DELTA Pro, with a solar panel included in the same order.
