Hi Canoe Yes toroid my own design (always) auto configured ( depends on type and application) electronics on certain models dependant on clients wish list via sine wave mapping, size dependent on model, the basic model fully rated BS Tested to 8 hrs continuous 60amp current and smaller than an...

Na, as long as you have open minds and are not closed to basic physics and maths then we all have hope. Lets put it this way, coming from a commercial aspect, if the DNOs were to say that you could fit as many PV systems in a street as you wanted as long as you controlled the Voltage at the...

like it Steptoe, we prefer selling through education not vapourware or as you put it bottled space Give me time and maybe just maybe I can get you guys to see the light :)

Why would Andrex sponsor a hospital for constipated men :slap sorry a megger add was at the bottom of the screen when I was asked its now Kash Flow :)

I thought I answered it !

Seems like again we will have to agree to disagree, I take your point on the bad installs causing problems by under sizing cables, too long runs etc but the harsh reality is that micro-generation does and will continue to push up the voltage on localised grids even with good quality installs.

Canoe, I get the distinct impression you have a real downer on the PV industry, there are quite a few systems out there and they are not all bad, the voltage tripping problem is not just down to 'muppets' as you put it

Sounds like my sort of place and apparently Steptoes :) If the grid voltage was 240v then the inverter would see 225v, it would then say export at 227v which would be stepped up back through the transformer to 242v maintain its 2v increase, if the current was utilised in the property then it...

HI STEPTOE, YOU SENT ME THE LINK FOR IT, JUST GET THEM FROM THERE AGAIN! DOW FEEL ANOTHER SCOOB COMING :facepalm:

or was that BASS BREWERY!! SORRY ONLY JOKING :)

Hehe, good-one Steptoe, no they don't, is that where you got your C&G certs from??

Hi Binky, also no its not a sales pitch, I have not nor will not mention my Company Hi canoe, eek! that's like you guys saying megger doesn't work :)

Hi Canoe, I have over 4000 systems installed in the UK to date so we have plenty of case studies in single and 3 phase systems, as I mentioned a while ago it is not just about the energy savings of typically 8%, its about the safety of the European equipment that we use in our houses, trust me a...

Hi Binky, of course they can if they are auto-transformer configured. if you subtract say 15v to the inverter then pushing current back through the transformer in the opposite direction will increase by the same amount, there is a slight problem in doing this though within regulations!

Its requesting an opinion to engage intelligent conversation, as a whole it has been I think! My role in life after getting bored with Electrical Installations was to develop Voltage Optimisation Technologies (no surprise there to you) What I am trying to do is introduce a realisation that VO...

Steptoe, I have no doubt you are a beer engineer.

Hi Binky Please take into account I am not a PV Engineer but a power Engineer, 1,  I tested an inverter that had arrived into the Country 3 weeks ago labelled G83-2 and it was set at 262v, I can only presume Manufacturers would set them at 253 to comply with G59 and G83-2,would this seem right...

Hi Canoeboy, it was you that mentioned the ENA, all I did was gave you the facts from them. Smart metering is there for measuring not only peoples bills remotely but also their voltage levels and also reactive power etc, (don't worry guys I am totally aware we are not charged for this...

Actually KME its a little bit of all of them put together, we realise (as hopefully by now others may on the forum) that the DNOs keep the voltage on the high side for voltage drop and additional revenue.. Additionally our localised network lines have a fixed resistance, when a load is placed...

KME, we agree on something at least, the v-phase product was not very good, there are a lot better whole house solutions available on the market today, but unfortunately the rest of your statement is silly, the over-voltage issue is something us householders and engineers will be dealing with...
