You need to know the current your inverter can supply, to calculate the
wattage of the resistor, and your capacitor must be able to handle the
voltage (250V).

And a box to put it in.

Better be a strong and fireproof box. 240V across 470uF is going to be
about 40 amps, with results that would have been just right for for last
Thursday.
(and you'd have to find a 470uF cap that could take AC mains voltages,
not an electrolytic)

You might get away with an LC filter; the L would have to be big and then
the C could be smaller. The real answer is to get a proper sinewave
inverter if square waves aren't acceptable. It'll costyer...
