If you create a file called /etc/mg_ignore_110_fcc the FW will not limit the 1100W. Note that this mode of work is not well tested by me, and can cause extreme heat in some cables. Make sure you have proper cables that match the amperage of the system. We take no responsibility of any damage done to the miner, PSU or your house if you set this flag. The PSU supports up to 14.5 Amper, so make the proper computation (and don't forget to add 10% to SP10 limit for PSU efficiency).
Can you give us some values to play with then?
You have to know the cables you have. There are 16A cables sold in stores. PSU supports 14.5A which is your limit. You have 110V.
14.5 * 110V = 1595W
PSU efficiency in 110V is ~85%, so your limit is 1595*0.85 is over 1300W, so it looks like assuming you have 16A cables you are clear to go. But if your voltage is 100V (which can happen) then you are limited more.
Just make sure you have 16A cables.
I have 240V - One miner is pulling is 224V and the other 227V. I guess this is for 110V guys?
