oh I see, so instead of lowering the freq across all boards just run less of them?

That would be an option too, but you can also use custom firmware like Vnish or Braiins to underclock the miner to the point where it's safe to run on 110v, it also depends on what PSU you have, even the stock PSU models have a different rating, APW7 and APW3 have different capacity, you need to read the specs on the PSU I think it's 900-1200w for 110V.

You could also use stock firmware, there is one called multi-option user firmware, this is the link from the official bitmain website https://shop.bitmain.com/support/download?archivesId=007201606150352305686UFyndN10697&type=0

you can try to lower the hash rate by 1-2-3 terahash or go straight to the LPM (low power mode) which does about 80w/th and gives you 9th, so close to 720w which I think would be safe to run on 110v, but please make sure to read the specs on the PSU and also make sure to measure the power at the wall because the 80w/th is just a general number, every miner has its own numbers.

And don't run any non-Asicboost firmware, even Vnish comes with AB disabled (no clue why they do it), running stock setting without AB will surely pull over 1350w (more like 1400w) which is likely way above the max of Bitmain's PSUs on 110v.
