Solar??? Eh?

Thats what I'm getting at Dave . Didn't think a step down transformer would be able to step up a back fed voltage .

Why not? A transformer is two coils of wire around a core, why would it care which way the flow of energy is?

Yep been on google and have learnt something .

A good question with some great answers! Nothing to add but it is good to see some helpful pointers for further research

I thought I should mention Kirchoff's first law to the OP in case he wants further reading.

I was racking my brain for ages last night trying to remember the blokes name to post that here!

ha.youse all wrong. DNOsite transformers in the open air for a reason. when sunn shines, photons from the sunlight push the DNOs electrons back to them, thus generating the export tarrifs. when uit's dark, the electrons pushback, thus shoving up our bills. ssssimpesssss.

Hi,

ok, can someone explain because I'm confused and never know what to tell people.

so you have a normal supply into your house, and you have PV on your roof.

why or how is it that your consumer unit chooses to draw its power from the PV and not the grid?

how does the power back feed in to the grid? I know how it's all connected, just wondering why say the grid doesn't push in to the inverter and not the other way round?

am I missing the obvious?
