Heya all,
I'm hoping to do a PV based system for a uni project but i've got a couple of questions, including hooking up to the mains.
Here in the UK we can get solar cells put on the roof of our homes and sell the electricity produced back to the national grid. I'm hoping to make a system to monitor the electricity outputted to the grid (and hence how much money you will have earned).
I know that PV cells produce DC but the mains is AC. Using current systems, does the DC output get inverted to 230v AC or simply outputted as it is generated?
If it is converted to AC is there any issue with getting the phases of the mains and inverted sine waves to match up or can you output it without this concern?
