In theory, yes. However, there are done fairly big caveats that come with that yes;
1) Current draw. To be honest if you are looking at anything over 1000w I'd recommend sticking with the generator in your case.
2) How many hours run time the motor averages per day. If you are say a contractor who uses it all day every day and it runs say 50% of the time, you
are asking a lot from a battery pack. The big problem is you need to replace all that electricity you have used, so you are going to need a serious
charging rig to look after it. We've got a battery powered forklift at work,so it is possible, but it has a lot of batteries in it and the charger is
a seriously heavy duty unit.
3) Cost. It's not likely to be cheap to put together a rig that will meet your needs. The generator may work out to be more cost effective from a
business point of view. Remember that batteries don't last forever so they will eventually need replacing too.
All in all, from what you have asked, I would estimate that here in Australia, it would cost at least as much, probably more for your kind of setup
that you need as it would for a good quality branded generator. And that's just for the batteries. You'd still need a charger and an inverter on top
of that. I am basing all of this on your air compressor being one of the types with a tank on it, not one of the baby ones.
Battery packs and inverters are best suited for light to moderate loads. To use my caravan as an example yet again, the lighting only draws around 18w
when all turned on thanks to led technology. The other appliances except the tv are only run for a few minutes a day when I use them and the tv draws
60w. This kind of usage is fine for a solar powered battery pack as it gives it plenty of time to recharge during the day and is only putting fairly
light loads on it
