Tesla Gateway switch

[SPECIAL LOCATION]

Hey guys,

Am I reading this right, is this device an automatic changeover switch, that would work like a Tesla Gateway?

Ignoring the technical aspects (or not) of this item... Have you looked the the reviews?

Less than 50% are "5-star"... Just under a quarter (23%) are "1-star"!!

As Binky said... best not touched with a Barge-Pole unless you have money to burn!

And for your future reference.. since 1995 UK voltage has been defined as 230volt +10% -6%
which gives a voltage range from 216.2v to 253.0v

Pre 1995 it was defined as... 240volt v +6% -6%
which gave a voltage range from 225.6v to 254.4.

In reality many UK single-phase supplies are frequently 240v+

So any equipment which is not designed to operate, continually and reliably in the 240v+ range...
will probably fail prematurely. (e.g. as per far too many LED lamps!!!!)

How are you connecting the additional CU?

Directly on the meter tails before the change over switch.

Well why didn't you say so before .

I'm with you now, that would work

Probably due to old age and pork sausage sized fingers on a tiny keyboard or I was just lazy and expected you to work it out

I really don't understand why what I'm suggesting is an issue.

Twice a year I will flip the main switch in my CU, and turn the changeover switch to EPS, then back again 10months later.

Where does the feed from the EPS go to?

There is such a thing as legal compliance, what I and John have suggested is legally compliant.

 

[Mrjmegson]

Nooooo, that's not the way to do it.

Connect AC inverter supply to the CU, on it's own circuit, connect EPS to change over switch , with the switch mounted in the meter tails. I'm not sure exactly what happens with the EPS feeding the CU, you might have to switch off the inverter cct

There is such a thing as legal compliance, what I and John have suggested is legally compliant.

That's cool, I obviously want to be compliant, and if you say that is, then I'll take your word for it, and it's pretty much as easy to do as the way I was going to do it.

Cheers

Where does the feed from the EPS go to?

Currently, nowhere, I haven't used it. I only want to use it as the inverters won't supply a current draw under 200w while grid tied, which leaves us using 3kw a day. As most things we have in our house are very low power, the only things the inverters kick in for are the big power appliances.

 

[Mrjmegson]

So I've looked at the changeover switch you linked to on TLC, and I simply wouldn't have room for it, and I'm assuming I would need one for each inverter, so need two of them. The space under the meter is 130mm X 140mm

So looks like I'm out of luck, I'll have to put up with my 3kwh usage a day.

What about this one then, 400V
