In this case I would (your system would not be running for extended periods of time at levels exceeding ~1250W).
As for how the HCP 1300 can handle 1.6KW DC loads, I'm not sure what kind of explanation you expect. Circuit dissection and component analysis? Or maybe a test to showcase it?
The simple answer would sound like this: it's thoroughly over-engineered and overbuilt, and, like its predecessor, it overloads beautifully, performing better at 20-30% overload than all its competitors (at that output level) do while in spec.
You can see a review here, it's in Koren but don't panic, graphs are self-explanatory and you can use Google Translate to decipher the text. You can see the unit there drawing 1800W+ from the wall while delivering close to 1600W DC, all this while keeping all 12V rails at 0.5% (or lower) deviation from standby value.
