Ok, so, in order to export the voltage needs to be fractionally higher than network. We both agree on this.Just think of voltage, like pressure in a water pipe, the water will always flow to the point of lowest pressure. The same is true of electricity, for current to flow the voltage must be higher than the the background voltage, its called potential difference. Turning on a switch lowers the voltage and current flows into the light/ motor whatever to correct the difference
Current comes from the mains but you can push it back up by raising your voltage, this will only be a very small amount as the grid can absorb an awful lot and you will be limited by the wires to your source. The lighter the wiring the higher you will have to push the voltage to force the current back.
I think you are confused by the alternating nature of DC where the power is indeed pulsating, but the current is actually only ever flowing in one direction
Amps control the level of power, and these are fused. You draw more amps than you're aloud and you burn out the fuse. The network transmits in fluctuations which is why you have a transformer. The network can fluctuate between 240/266V.
The inverter measures this and live time alters the volts increasing its output slightly higher than the network. If this pushes export through higher voltage then this should fully push through at main board.
If it works on a pressure higher then this surely would push through stockpiling the network which back south England's full network capacity with the DNO not accepting grid connections for solar a year or so ago. That network couldn't handle anymore capacity whether it was on a business that would use all of this or in a field.
Concessions were then made if you applied limiters. Now, limiters work by shutting down inverters. You replace network capacity by drawing from the grid in equal measures, the capacity.
There was a rumour a few years ago that new metering would give DNO power to operate generation stations, solar, wind. They would switch them off when demand was low and switch them on when demand was high (wind farms) yes these are grid tied only but it was rumoured to eventually be ever generation station on the network with compensation for downtime.
I'm going to add this to my downtime research and I want to know exactly the behaviour of the inverter versus the network and need to find someone in metering to give me a run through as I'm not convinced. This could be the biggest rip off ever if you're not consuming more than half your generation then buying it back after selling it for 1/3 its value.
