Inverters?

You're thinking in terms of output... the current draw is 147 amps from the battery with 15% lost (to heat) and the remaining 85% going to the blender/pump/load as AC power.

To get the 1,500 watts to the load the battery needs to "produce" 1,764 watts at 12VDC.

Yes I was figuring output as that's where the load is you need to satisfy. Now that I think about it you would need to know the draw on the battery for fusing and wire gauge. Thanks for the clarification @Bill D and @Bruce.
