Questions about this item

Should I pick the 1440 VA or 1350 W rating when sizing my load?

Size the load by the 1350 W figure; the 1440 VA rating is the apparent power limit and will be reached first only with low power-factor devices.

What does the 1350 W rating actually support on a 120 V circuit?

It delivers up to 1350 W of real power to connected equipment while the battery maintains output during an outage.

What input connection does the 120 V model use and what does it limit?

The unit plugs into a standard 120 V receptacle, capping input current to what that circuit can supply.
