There are 2 main invertor options, sine or modified sine, which is IRL

MSW, so all your apps ideally want sine. However MSW is much cheaper,
and there are workarounds. Fl lights can be run at just slightly
reduced power, or heatsinks added to the ballasts, etc. Electronic
ballast lights would run happily on 150v dc. Motor driven tools would
be fine as is unless youre running them to where they already get
seriously hot, ie heavy use. There are ways round it if it proves to be
an issue.

Small point.

Why would anybody modify a sine wave?

When people try to sell a "Modified Sine wave" inverter they are either
ignorant or shysters.

To paraphrase a classic George Carlin routine- "I'll tell you what
'modified sine wave' means-- no f*cking sine waves".
