Plug in balcony solar UK , just a Lidl question

[denso13]

but I'm still a bit confused

Me too

However, perhaps what you are implying......

I never thought that you were 'implying' anything.....

The battery box can discharge at maximum rate for battery through the socket on the front and supplement the deficit by drawing direct from the mains, so say 1 kW from battery and 1 kW from mains so a 2 kW output, and long as the output is less than 1 kW when mains is disconnected it will operate like an UPS, but since it will allow a mixture of mains and battery as it has grid tied, it can allow you to use part solar generated and part from grid.

The problem I have is the English, both types are tied to the grid, but one type back feeds the other type does not, I don't know of a phrase to differentiate between the two. They both grid tie.

As to feed into grid, as far as I am aware, my solar does not have an option to reduce its output so it does not feed into the grid, if my battery state of charge is below 100% then that will be charged first, and if my immersion heater calls for heat, that will also happen before and feed into the grid, but I have no way other than turning it off, or for the grid to be out of range, to turn the output off, at the moment 1 kW is going into the grid.

Only way not to feed into the grid is with say a 300 watts panel and a 350 watts back ground load.

My goodness, we do seem to have confused one another

This exchange started when you asked (in response to my statement about 'if export never occurred'):

Is that technically possible though?

... and I responded ....

It would be difficult, if not impossible, to ensure, 'technologically', that there would never be any export ....

Which, as I've said, seemed to be an answer to your question - but in the same post, I then went on to explain that I doubted that these didy PV things would produce enough for their to be significant export but neverless went on to repeat/reinforce the answer I thought I'd just given to your question, when I wrote: ...

.... However, perhaps what you are implying, there could not be a guarantee that export wouldn't happen sometimes (sunny days with low electrical loads)

... but you responded to that with:

I'm wondering the opposite really, I think, the new product standard has yet yo be released. Could they be designed with a guarantee not to export.

...which seemed to me the same question which I thought I had already answered, at least twice

So, just to be absolutely sure, what I've been trying to say is that (rightly or wrongly), then I would struggle to see how it would be possible to ('technologically') design a 'plug-in' system which was guaranteed never to export.

I am, of course, talking about what I would regard as being a 'plug-in' system - i.e. a PV inverter that could be plugged into an 'ordinary BS1363 socket in any installation. In that situation, if the voltage output of the inverter is high enough to be able to supply local loads (i.e. slightly higher than grid voltage) then I think that it would inevitably also do at least a little exporting (since the inverter voltage had to be slightly above grid voltage) ... per 'the Laws of Physics'

Kind Regards, John

All noted and I did, I think, understand from the beginning. I was just thrown by "perhaps what you are implying", when I don't think, or didn't mean to, imply anything in anything I said/asked.

No problem though, I've maybe misunderstood that bit.
