I think you may be defeating the effect of return voltage by inverting the DC voltage to AC, the IRFPG50 Mosfet is only rated at 1000 volts ( International Rectifier - IRFPG50 HEXFET® Power MOSFET ) and using 24 VDC battery source and a prototype 32mm diameter load resistor the mosfet drain voltage is over 500 volts. If using a prototype 76mm diameter load resistor the mosfet drain voltage is over 800 volts, nearing the voltage limitations of this "Avalanche" rated mosfet and any standard equipment to monitor the mosfet drain voltage.
The other problem is any inverter would have to withstand return voltage spikes from the prototype load resistor from 60 to 100 volts using a 24 VDC Battery Bank power supply.
