Plug in solar

[ericmark]

I have wondered where the inverter measures to decide how much to put into batteries etc. I how plug in solar would integrate or not with the existing solar.

As it stands, it does not matter, the tariffs mean I get more for export (12p) to what I pay for off-peak (8.625p) so the easy option is to fully charge overnight and then export when/if the sun is bright enough.

Yesterday was rather a bad day for solar (4.3 kWh) but still enough together with the off-peak, to see me until the next off-peak today started. To try to guess how much off-peak required is near impossible, and should the off-peak become more expensive or the export pay less, then I would need to consider a third battery, and/or some solar panels to catch the morning sun.

I think I am understanding @ebee in that the batteries and plug in solar are separate units, for example a V2G EV outlet plugged into a car, which is a plug in battery, independent of plug in solar, but to have a V2G EV charge point, a G99 would need submitting, output too high for G98, I suppose you can have an EV motorhome with solar panels on the roof, so in real terms we have two completely different plug-in solar systems.

There can be no denial that it is permitted to plug-in portable batteries in the form of an EV. So I suppose it should be called BS1363-solar so it is clear which plug-in system is being talked about?

So is using solar to heat domestic hot water considered as having storage? Even the word battery is a problem, if someone develops a 50 volt cell, then that's not a battery.

However,

the point is, these things are terrible value for money leaving those who are daft enough to buy them considerably out of pocket.

this is true, so in real terms we still do not have plug and play solar.

3.3 Household
A single dwelling unit with its own electricity supply and consumer unit. In buildings containing
multiple dwellings (e.g. blocks of flats, converted houses), each dwelling with its own consumer
unit is treated as a separate household.

That is it would seem incorrect, the local council use very different rules, I have one consumer unit and one meter supplying both main house and flat under the main house, and each has its own council tax charges, its own bins, believe me, I wish that was not the case, it costs me £1000 a year because there are no internal stairs between the two.

I have tried to argue that a 60 amp supply to two kitchens, two bathrooms with electric showers, would never work unless the occupants of both main house and flat were a family who lived together, so did not use both bathrooms at the same time or both kitchens at the same time, but it seems the supply has nothing to do with it, it is all down to the access between the two being external.

So what, the council don't make the plug in solar rules.

this is true, so in real terms we still do not have plug and play solar.

Of course we do, only on day two, once things settle prices will drop substantially. If there is only one on the market it will invariably come at a premium.
