12V Pure Sine Inverter for 240VAC Well Pump ...

In my opinion (and everyone can feel free to disagree with me) this is too heavy a power requirement for a 12 Volt inverter. The start-up current would require a 5-6 kW inverter, which just don't come in 12V. Not pure sine, anyway, and you are right to want sine wave for the pump motor. Never rely on an inverter's surge rating for anything.

How do I calculate what resistor I would need? - Instructables

A voltage divider usually isn't a good choice for a current source. To get any useful current from that divider would require very low resistance values (like 2 ohm & 10 ohm), which makes the divider very inefficient. In the drawing above, the most current the 5000 ohm resistor will pass will be around 2 milliAmps (0.002 amps).
