Can you power up an inverter with AC without connecting a battery?

Can we get some more info? What inverter? 

It really depens on which inverter you have. I have the Kodak Hybrid off grid 7.2kW and it cannot start without a battery. Friend of mine has an older Goodwe 6kW grid tied inverter and it can start without a battery.

Battery-less operation is a feature of some inverters,not all

Sorry for little info before. It's a SUN 2kva inverter. It didn't work without the battery connection

Does anyone have any info about these inverters? The fan on mine just keeps running even when it's on AC bypass.

I think an inverters core function is to produce 220V AC either from battery or from PV. True hybrids do it from either/both.

Some always stay on and ramp up. Budgetish ones tend to be louder-er permanently

OMG. I can't cope. I have it in the living room at the moment and was planning to mount it in my office.

Guess I'll just have to keep my noise cancelling headphones on 😔

The Kodak 7. 2 actually can power up from grid only, or pv only. So it does not  insist on battery power being available. 

growattspf5000es runs perfectly without a battery but you need to decent solar panels and NO clouds.

Not really recommended/ideal to run like this.

You would rather run a grid-tie inverter if you do not have batteries.
