That much converter is going to be about 25 kW to 30 kW, depending on how you figure it. I can say kW, because the PP has an input power factor correction circuit, and should draw power as a nearly resistive load.
So at 240V, that is 125A Generally well within what can be supplied, because nearly any service is rated for 200A, even a house service.
BUT, your box is not the only limit... Assuming you ever actually DRAW 30 kW, the pole transformer may, or may not, be good for it. The power company often applies a correction , or "diversity" factor, that takes account of the "usual" loads for the type of service you have. Then they put up a transformer that serves THAT assumed load. They KNOW it will be overloaded part of the time, but they figure it's cheaper not to put up one that serves the maximum load, because it rarely occurs. Same with the wires to connect it to you, they are usually sized for "average" loads..
They are betting on the average loads, and figure the equipment will not overheat in the short time a maximum load is applied
So then you come along, hang another up to 30kW on their line, and fry the transformer, maybe.
