I don't know that unit.

Can you post a photo with the lid off, it may be possible to adjust the internal wiring so you don't need the isolator.

Great.

Please confirm that:-

1. The incoming supply is at 'A'
2. Points 'B' and 'C' are linked by internal wiring (it's not clear on the image)

If my assertion is correct you can remove the links 'B' to 'C' and insert your AVR, no need for an external isolator and a neat job.

Point 'B' would also be a good place to connect your surge arrestor, before the sensitive RCD section.

Yes, A, B, C are as you say...

I'd figured I could wire in between B and C if wanting to position the stabiliser inside the house (under the CU) but, because these things are supposed to be a bit noisy (clunky, click sounds as the servo shifts), I'm thinking to split the incoming feed wires from the meter just before they go into the house and work some external housing for the MCB, SCD and stabiliser. Will see what can be done when I get the stuff and local electrician together.

There is http://www.siliconthai.com who make non-servo (so quiet) stabilisers - but these are apparently a lot more expensive.

Cheers.

Be aware that the totally silent (ferro-resonant) stabilisers become rather inefficient at low loads (and are very expensive in the sizes we are talking about).

Tap changers click, we have a baby one (2kVA) and its noises are intrusive.

Servos tend to whirr.

A lot depends upon how often your voltage actually changes. The occasional whirr isn't going to be annoying, constant up and down adjustments will be somewhat wearing.

I've got 3 Lioa 10000 units outside. I dont notice then werring or clicking inside the house, but if im outside sitting near them when something exciting is happening with them, the noise is not too bad but better to place the units where you can't hear them.

Got it installed. Went for outside as was worried about annoying noises - turn out it's really not loud when it adjusts so, unless you have it right next to you, doubt it would be a bother. (Though not heard the cooling fan come on and that might make more of a noise.)

Tried it with 4 ac and a few fans on - voltage steady, amps up to 45ish. Although the draw on the soi transformer isn't bad like it was a few weeks back before the rains dropped the temperature, pretty sure we could never have managed 4 ac on then or at any time... So, seems to do the job.

Great

Got some photos of the installation?

It would also be interesting to see the input / output voltage and current.

This morning input is 210v and output is 235v on my meter. Nothing really running in the house (or soi) so the Amps gauge isn't reading - like I said, last night with 4 ac on + fans it was up to 45ish - holding 235v steady. (Input would have likely been lower then but didn't read.)

It would be interesting to see readings when the soi transformer is really struggling but that likely won't happen now till next hot season. That will be the real test for it...

63A MCB and Surge Protection Device inline. Needs a bit more mesh, latches and holes to help ventilation and deter critters.

Looks good

Since the unit has a cooling fan, if it's reasonably easy to get at the fan connections why not wire an exhaust fan in / near the top of your box to help it along when it's working hard?

Thread started 12/5, solution installed 27/5, OP happy

If i notice the fan on lots then I might - but it's not even turned on yet.

Looking at the picture, and maybe had one small LEo to many, but why not face the unit towards the door so you can see the meter?

Installation looks nice though. ?

Cos then it wouldn't fit in the enclosure (HomePro kitchen cabinet thing). You can still just about see the guages - and easy enough to put your hand down the side gap and view better using a small mirror.

Send one more time if you are trying to escape and need help.

I have enclosed a pic of my small meter I installed to check the genset output when connected to the house load.

Not hard to install and available on ebay.

Maybe that is me you are refering to?

Told SWMBO that all power is now Ok on the genset, while i had the genset going at about 14 A load, so she decided to start ironing.

This tripped the genset breaker, so while i was posting to Tv my wifi was on off on. Sorry to get you excited if it was me.

Also,

While we are still friends, i did notice that my genset specs say something like 25 A and 5 kva or around 5.5 kva depending where you read, and when i start to load the beautiful little thing up, voltage O/P starts to drop around 15A.

I will have to read further, one day, but bit hard to load my beautiful little diesel further to 90% of load, when it seems to be complaining about 15 A.

Maybe the Chinese specs are a bit slanted. He he he. ?

How many kW is the iron?

How many Amps is the breaker that opened?

Oh, and does the genset feed the input or output side of your AVRs?

Hi crossy.

Didn't give it that much technical thought when the breaker tripped, but the iron is 2400 W or draws about 11 A (i suppose when turned on).

That 11 A plus my other house load of 14 odd A is enough to exceed the genset spec of 22.7 A.

Not sure as yet of the gen set breaker rating.

Really never considered an iron would draw that much current.

Now I know.

Are you typing replies? None of your recent posts seem to contain any text.

The gen set feeds into the changeover switch. Changeover switch is: mains on genset off, both off, genset on mains off.

I have changed to the full version from the mobile version.

Can you see this reply?

I can see all the conversations on my samsung phone. All have text. ?

It's like my pictures, all look correctly oriented when i send them.

Will have to use my computer with TV.

Where are the AVRs in relation to the changeover?

Genset breaker rating?
