Hi all,
I have been doing some PV installs in Northern Ireland for a local outfit just over the border (I am in the South) Anyway to my questions. As the title says, please don't sit there smirking and shaking your head.... :facepalm:
1 If a PV works by putting out a voltage slightly higher than the supply, then the power goes 'out' if not used, thats fair enough. Now if you had a number of houses close together could you have a situation where each inverter has to jack the voltage up to fight against the neighbours' inverters, if you follow what I mean. Could this spiral up till all inverters shut down?
2 They tell me that your exported energy, if any, goes out on the street and gets sucked in by someone else. Again that sounds fair enough. However, I have fitted PV on farms where the only house on the transformer is the one on which I am working. Now if the farm is using say 3kW but the inverter is making 5kW then the excess must flow in to the transformer and 'out' the HV side.
Great forum by the way, it has been good watching it all develop...
