Inverter beeping

Does the inverter beep or show error code if you have no wires/no AC plugs connected to the inverter AC outputs except the positive and negative wires to DC input to the inverter from battery?
 
Yeah, good point @Bud Martin
My Inverter do bip if I plug a fridge before turning it on. So I have my house breaker all set to OFF when I turn on the inverter. Then after about 5-10sec, when the voltage display stabilized on the inverter, I turn all my house breaker ON.

The inverter beeps and give F05/F04 errors. When I have ground connected to nuetral it show F05 and when it’s not connected I get F04.

So I thought that was the issue so when I disconnected the wires from the inverter output it beeps and the volts go up to 222 and back to 221 and then shows F05 error. Does that mean it’s getting too much power?
 
Essentially, if your input voltage is >12VDC, you have absolutely nothing connected to the output, I can only conclude your inverter is defective.

Is there anything odd on the DC side? Is your DC (-) grounded in any way?

I don’t have anything connected to the DC side.

The white code that was connected was just to lights and outlets. They haven’t been grounded. I wanted to see if I could get this thing to work. I also thought the grounding wire they provided would do that. Is my thinking incorrect?

I was thinking it was bad too but didn’t want to jump and order another and have the same issue.

The spec of this inverter is 120VAC output, correct, as marked on the box? So the AC Volt meter on the inverter shows 222VAC?
It should not have any error at all if there is nothing connected to any of the AC outlet, it should come on and stay on and put out correct AC output.
Look at it this way, if you do not need to use the AC output terminal and just want to use the two AC outlet, the unit should not care if you have nothing connected to the AC output terminals, some of these units are not made to have Neutral and Ground tied together.
Do you have the link to the user manual or where you buy this unit from?

I could not find much info about the unit, especially the error code.
Is the unit still under return date?
 
So I sent back inverter and I was sent another. It seemed to work but with a different issue.
 
inverter in shutting down and then spikes to 30v. Comes back on and then voltage drops and it shuts off. Cycle repeats.
Looks like you have another bad product. I can only suggest you send it back and get a refund as the reviews for that inverter are horrid.
 
I have and update.

I purchased another inverter, however it wasn’t a pure sine. I bought a modified sine. I know it is recommended against it but I thought it could work for what I was doing.

It is a Topbull 3000w Inverter. I plugged it in and light work great. No surge or shortage. I pulled in the portable AC and still no shutting off.

I will be adding a laser cutter, 3d printer, computer, TV and small random appliances.

So now the question is do I change to pure sine or leave as is?

Look, it matters not what anyone says but if if it is working for you want then all is ok. I have had modified sine waves that don’t work with say a computer and yet another one will. If yours is working with what you want then there is no reason to change but remember it will have its limitation. I suggest trying it on all appliances that you will be using Then decide whether it is suitable.
