The net readings are always taken after the charge has finished and the battery in idle mode
Intrigued by this story as we are also with EoN and considering replacing our FIT system; and was wondering how you got EoN to agree to an increase in the inverter size as well as increasing the size of the array which will surely increase your earnings, am I understanding this correctly?
On the meter issue, I assume you used to have a separate FIT meter that you read each quarter and reported to EoN who then paid you for the kWh generated. We’ve just had our old black meter changed for a smart meter so we can use Octopus Intelligent Go and that has two registers, consumed and generated. In one of our properties we had a tenant arrange a meter change without us knowing about it and that just had one register which apparently could run in reverse, but it wasn’t smart. We’ve been told by Octopus that when we get out export MPAN they’ll use the export register for payments, but only if we move from deemed export on our FiT to their export. Probably not very helpful to you, but just out experience.
What did your installer say? Will they come and double check the meter is wired correctly?
I’ve asked for them to visit but due to illness their technical director has had to step in to help out at the coal face, he hopes to come sometime towards the end of next week.
Do you think thats the problem?
Do you have a wireing configuration you could share with me so when he comes i can check his observations
Can you suggest a good set up for the inverter with this system?
At the moment my setings are, eco on and a forced charge from the grid between the hours of midnight to 7.00 am. The battery starts to charge at midnight until full then the system or battery goes into idle mode untill 7.00 am (the grid services the house in this period) and then kicks in to service the house.
The idea being the system does not draw on the battery for 7 hours, effectively giving the battery more capacity because it only has to service the house for 17 hours not 24
Do you think it would be a good strategy to do a forced discharge so that the battery is at or near zero just prior to charging.
Actually thinking about the last point a bit more all that would do is discharge any latent pv energy stored in the battery into the grid.
Not sure. But it could be a good guess.
I assume you get cheap power overnight, if not, there’s no point charging from the grid as it wastes money.
Equally force exporting is only worth it if you have measured export (e.g. SEG or FIT that isn’t deemed).
Yes charge from the grid because its 7 p per kwh

So you can see from my pv generation profile over the last month and it is clear if you deduct the kwhs that went to the battery and grid export from the home consumption figure the sum equals or is damn near the net meter reading of 18.4 kwhs .
