Lights flicker using Aurber DSPR1 or other Burst fire controller

[Yummyrum]

I'm wondering how common this is .There are a lot of Auber units out there now .
( also this is not a bad mouthing of the Auber controller , I really think it is a great unit , just not in my case )

I mentioned in my DIY Burst-fire controller topic that I have really bad flicker of the House lights when I am running my still .
A couple there said they had not noticed it , but I am wondering if anyone else has this issue .

It effects all my Dimmable LED lights , our Fluoro's and even incandescent lamps which really surprised me . I have a few Non dimmable LED lights and they seem to cope better.

Running a 2kw element I can barely notice it , but running the 6kw , it is bad . I can cope with it but it annoys the hell out of Mrs Yummy and my son .So 'Stillin days are short and only when its really sunny .

So I have a Shed that has it's own sub panel and is about 40 metres from the main house fuse box .
My son is in a granny flat . He is about 20 meters from house fuse box with his own sub panel .

the problem seems to be that when the element turns on and off there is about a 20 volt difference in voltage due to the drop from the Street transformer and the cable to the shed . A significant amount must be dropping on the street wiring because the voltage at the house varies by about 15 volts from on to off . This constant change in voltage makes the house , granny flat and shed lights flicker .
The obvious work around would be to have a bank of lower power elements and that are individually switched on and only control one of them , but that is messy .
I am incidentally going to move back to a phase controller to keep the peace in the household .
We also have a new 8kw Solar installation , I would have thought that that would have helped with the regulation , but it makes no difference if it is on or off .

Am I alone ? is anyone else suffering this ?

My advise before going down the Auber route would be to flick your element on and off and see if your lights change brightness. If they do , you may have the same issue I'm having .
