Silly solar question for the day

(I'm due to have a RaR installation next week, so getting curious as to how it all works)
If we had a power cut on a sunny day, would I still have electricity in my house?
(I'm not as stupid as that question makes me sound, I presume the inverter is powered by the mains, but I just thought I'd ask...)
Cheers!

Not really a silly question, in a power cut, all the power would go off including the inverter, the inverter automatically shuts down in a power outage, to stop an engineer working on the lines getting a nasty wack (burnt or killed) from your system.
Once power is regained, the inverter will automatically switch on after 3 minutes.There are three types of people in this world...those that can count ...and those that can't!

Are you sure Harry Hill didn't write this heading?:rotfl:0 -
Not a silly question, When you think the power is transfered from the invertor to the mains board down a standard mains cable and this is then mixed with the electric coming into your house. how would it know if the electric coming into your house had stopped since the electric your panels are producing is already in the system. There is no cable/controller etc coming directly from the outside electric source telling it. The electric being generated must stop as already stated since you dont want to electicute a poor electricity engineer.
The answer lies in some quite clever electronics and the fact your inveretor generates electricity a few volts higher than what you recieve from the grid.0 -

And .... the inverter needs to match the frequency of the grid .... no A/C = no A/C frequency

Shame, really, as backup summer power would be mildly useful - but I suppose I could have just switched off my incoming power at the meter and tried to rely on solar for a period (given that under a RaR scheme I'm not interested in the profits). Of course, that would breach my RaR contract, so I wouldn't have done that anyway!
btw, where does the "solar" electricity meet the "nasty carbon" electricity? Do the outputs from the inverter head directly for the outside meter cupboard for combining there, or are they wired in to meet up with their ugly cousins from nasty smoky power stations in the main consumer unit?
Cheers!

All the electric meets up in your consumer box. Because the solar electric is slightly higher voltage it is used up first.0

Not worth what? The zero pounds I am paying? The £70 or so per year I'll save on my electricity? The enhancement (in my opinion) to the value of my property as a result? The amount I can buy the system out at in 10-15 years time?
Personally, with 4 young kids and a sizeable mortgage, I don't have £10k to spend on a personal installation, and I am motivated to reduce my carbon burden through my electricity usage. So I won't forget RaR, and it is worth "it" to me.
I don't care who makes money out of me for a product that I want to buy at a price I am prepared to pay.
But we all have our opinions, and you are entitled to yours just as much as I am entitled to my (correct) one!!!
