If you go inverter go true sine wave. Logic would say that square wave is less efficient as the square parts of wave only produces heat, not energy transfer when feeding a motor or transformer in the downstream device. There is usually a pretty good selection at Northerntool. Where in most cases you want extra headroom, in this case I would size not more than 150% max draw to get the most run time. Less is more here.
