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.

zvisha,

Maybe you shouldn't be encouraging this. The cables required need to be 20A for a continuous rating of 16A. The IEC 320 standard power cord for this rating is C19/C20 or C21/C22 connector/plug combination. However, these connectors will not fit the power supply which probably means the power supply was never intended (or tested) for 20A.

I don't encourage this. I think the disclaimer about "damage to your house" will make people consider. However, some people do have 16A cable and asked to enable this feature. It is way cheaper to buy proper cable then to install 220V. I found out there are some DCs in US that have 110V.
