Axpert grid question

[gallderhen]

Yo,

 

This is perhaps a rather silly question, but can an Axpert inverter be connected on the grid side via wall socket?

What I'm trying to get at is the following:
I've got a computer sitting in the granny flat of our home and as far as I can tell, the granny flat is running off of 1 20A breaker (it only has 1 or 2 wall plugs).

I only want to run this one computer off of an Axpert with batteries (for loadshedding purposes), as the other plug gets used for heavy duty stuff (like ironing) so wanted to know if its possible run the Axpert off of the 1 plug without having the wire it into my DB? Or can it only be wired into the DB?

 

Thanks in advance.

If you are talking about AC input into the Axpert then YES>  I do this with my small 1kva Axpert.

I also have a multiplug on the AC output which I then use extension cord to loads when needed. 

Make sure the AC input amps doesn't overload the plug rating.

Yes you can but your wall socket should be to speck with the max draw from the Axpert. So if the Axpert can draw a max of 20a your braker and plug should be able to handle that.

Plugs in South Africa are rated at 16 amps maximum. That is ±3500w.

The breakers are usually rated at 20amps because a circuit breaker is there to protect the wire. Not the plug or equipment. It is pretty standard that many plugs will be supplied by a single wire run.

The SANS documents around electrical installations allows just about anything to be plugged in. So there is no reason it would be illegal. But it certainly isn't advisable to run anything more than 3kW from a standard plug.

Returning to this, it's not so much about the ratings of the plugs, wires and isolators / circuit breakers, but rather about safety. 

The moment you feel comfortable enough to open the cover of any inverter, to "play" with the 220V electrical wires and connections, you automatically feel comfortable doing something like this, i.e. hooking up an inverter to a wall socket. Now, what stops you from putting a multi-plug on the feed connections of said inverter? OR worse, another 3 point plug, to plug back into the wall socket! 

 

There's a good reason why you shouldn't hook an inverter upto a wall socket.
