Sockets can be any amperage. The ones on the shelf at Home Depot are only 30 amps.
It is a VERY bad idea to use a male ended cord exiting the inverter.

OK, thanks for your idea.
Stay safe!
with that amount of power, is it safer to hardwire it to dc circuit breakers (no spark) skip the plug in

Not practical.
The plugs are not being used as removable. Just a connection.
You see the giant orange knife switch?
That is how I am switching from grid to batteries.

All hooked up and juice flowing.
PS - 6 awg cable is just too big, 10 works fine.

I gave the batteries about 15 hours of charging. The entire setup was stable at 54.0V, but each "pack" was quite different. (Yes they should be balanced, no I'm not going to, for now)
When I switched over to the packs the heater ran for about 15 minutes, I turned on the refrigerator, the deep freeze, the water cooler (all 4 have induction motors), 23 lights, a big TV and sound system, and a big computer, plus all the wifi stuff.
After running the entire house off the batteries, they are at 52.9V.
I'm not sure what you call my system. A/C or D/C coupled, but it works great.
In grid-tied mode, my inverters are just chargers for the batteries.
In off-grid mode, my inverters run the entire house from the batteries.
To change from grid-tied to off-grid;
#1 Turn OFF the load's panel from the grid, at the main switch to the panel.
#2 Switch the giant orange knife switch from Source to Supply.
#3 Turn ON the inverters.
This is a manual operation, and yes there is a chance it can be done completely wrong, ie supply the output from the grid!
It is possible to through the knife switch with everything on. If done a few times it is just going to weld itself in place finally. Turn that stuff off before switching anything!

1st 6 hour run.
The batteries go from 54.7V to 52.9V in about 10 minutes and remained there for 5 hours.
At 5 hour mark, the V is at 52.7V.
I charged to 54.7 last night, and 54.0 the night before. Tonight I'm going to just charge to 52.9V, they seam pretty happy there.
My first 6 hours of off-grid use. (I only need it for 5 hours)
I have no idea how long I can go with these graphs on battery power or how much kWh of storage this is.

As of yesterday(30 December 2019), the batteries have all equalized to 2 decimals voltage. I charged them bulk at 56.5V (28.25V), after the bulk charge, they absorb to 53.0 or 53.1.
They were as much as .65 off for the pair, now one pair is 0.03 is the worst. Pair 2 are equal, the other two are 0.01 different.
26.55 26.52 | 26.53 26.53 | 26.53 26.54 | 26.54 26.53
Today after 4 hours of use the 52.6 V show.
Friday I am going to try a 24-hour push.
