Inverter Beeping all the time

Hi all

My inverter beeps constantly during loadshedding and I am wondering if anyone here can tell me why and what I can do to stop it. The beeps come at different times and at different speeds. Sometimes long constant beeps and some times short beeps. Sometimes beeps outside of loadshedding as well.

Attached are pics of the model number and front panel. I have seen other posts on this forum with the same front panel so hoping some of you can teach me a thing or two about this inverter. The picture of the panel is when it is not beeping. When it is beeping the word "FAULT" appears the right of OUTPUT below VAC. It is currently beeping as I am typing and we are not in loadshedding.

Another problem I am having is that the inverter will beep a few times and then cut the power (not during loadshedding) when we use a hairdryer in the bedrooms. I presume it is the safety feature that the inverter has which cuts the power when there is an overload. The strange thing is that when we use the hairdryer on the plugs in the kitchen we don't have this overload and all works fine. Very confusing because all the plugs in the house are on the inverter. Any idea why one circuit in the house could be overloaded by it and not the other circuit?

Thanks in advance for your input.

The bedroom plugs are on the Inverter...the kitchen plugs are not(for obvious reasons).

That's why you get 2 different results when using the hairdryer.

Also you are overloading the inverter....
 
Boy that electrician must surely hate OP, it's one thing wiring some dodgy inverter onto the DB but it's quite another not to even have the decency to explain to your client how it all works and what not to do.
 
Since 10 years ago whenever I buy a UPS or Inverter first thing I do is open it, look for that little black buzzer and yank it right out with pliers.

An electrician who does work for me installed it. What makes you say it is for IT use only?

Not all UPS models are made for home use. The fact that they expose connectors for electrical cable directly to a DB-board is because the intended use is in office RED plugs where laptops, screens and computers will be connected. Not high-draw home appliances.

So the electrician farks up , you conclude the inverter is dodgy ? Nice logic there ...

Dodgy in the sense that it shouldn't be connected to the DB, I thought you would follow.

Perhaps if you could word your sentence properly, it would make sense.

And any inverter could be wired to the DB.

If you're sure the plugs in the kitchen are running on the inverter (mains power is off / load shedding) then a possible answer is electrical resistance.

If the wiring from the DB to the kitchen plugs is longer or thinner (under specc'd) than the wiring to the bedrooms plugs, then the higher electrical resistance to the kitchen plugs will drop the amount of power being drawn by a resistive load such as a hairdrier.
Maybe just enough power reduction to fall within the inverter's limits.

Power = Current^2 * Resistance
The higher the resistance (Ohms) in the wiring the less power (Watts) transferred.
