what voltage for the 'house'?

Bob , don't you mean 60a*14v 840 watts
You know you can't charge 12v battery with 12v,bit requires a voltage, above battery nominal full charge which is 12.6v,
A fully charged fla battery should read 13+v when charging is turn off

Of course but the post was intended to emphasis the difference between 12V and 48V in terms of the controller output and the nominal solar panel wattage. But perhaps I should have qualified these are the generic voltages and I have now updated the post.

In that context what voltage would you suggest? 14.0, 14.4, 14.8, 56.0, 57.6, 59.2 or some other voltage which is dependent on the various mfg specs, not to mention that the voltage is also temperature dependent.

Or the commonly used terms of 12 or 48 volt battery systems. There is no one size fits all.

Tracer MPPT controllers at 12 or 24 volt specify max input power for their controllers. Eg. the "20 amp" size has :

260w for "12v" and 520W for "24v", but 260/20 =13v and 520/20 = 26v, so that's how they do it. (And other brands ISTR)
