More to the point, 16 A per phase is the maximum current you're allowed to back-feed into the LV mains without elaborate protection arrangements and approval of the DNO. (See ENA Engineering Recommendation G83/2.) This limits you to about 3.8 kVA on a single-phase connection.
Maybe but solar inverters aren't really inverters at all. They have much higher DC input voltages than the output AC voltage. You "only" need to change it to sine output using suitable switches and a bit of smoothing.
1) Solar panels don't need to be fitted to roofs 2) More than one supply and corresponding solar installation receiving a FIT payment per property was permitted 3)With a property having space for an array of more than 4kW you could size each 'installation' to be sub 4kW and optimise the return.
What do you mean you didn't have the common sense all those years back to request another metered conneciton from the DNO and could have got, in cash terms twice as much as you extort now from all those in fuel poverty?

2013, harryagain remarked:
Because it was only opened last year, and why would they put:
...LED replacements in fluorescent fittings, rather than use purpose-built LED fittings?
Yet you don't know the operating principle of the most numerous inverters made these days? About as much as you know about nuclear power. ie FA
Creating a sine wave using electronics is not straightforward.
You think?
I can do it in a line of code.
Now do it at 3KW....
A few electronic switches and a micro controller. They just get a bit expensive as the power goes up.
That dictates what is on the end of the ADC, not how you get it to produce a sine wave.
It depends how much distortion you can accept, but you've lost this argument before.
What would Russ Andrews do?
Use gold plated cables, probably.
With a special weave to remove the inevitable distortion and RF interference from the generator.
Drivel. Grid tie inverters are relatively cheap because they don't have to create their own sine wave out of nothing. They are more like an amplifier , input sinewave from the mains, so perfect sine wave and perfectly sychronised.
I see you are the theory man. Actually building a stand alone one that makes a stepless wave is difficult.
But unnessary in the case of a grid tie inverter which uses the mains as a "model" ie works like an amplifier.
Ah. The micro controller,
How efficient, harry, do you thing a 3KW audio amplifier running at 50HZ would be? Using class A, and Class B technologies.
You have no idea do you?

Harry..
Obtain an Oscilloscope then connect that to the output of any transformer or even direct to the mains and observe the mains waveform..
A Perfick sine wave is the one thing you will not see;!...
Den..
Its not quite that simple as you might realise if you know anything about it...
