The readings I am getting Fusion App and the online monitoring system I don’t think are correct.
I am not sure my power sensor and the inverter are calibrated/setup correctly as the PV output readings are showing directly proportional to the amount of power being drawn from the grid.
The more power I make the more I draw from the grid.
I would expect it to inversely proportional i.e. more power I make the less power I draw from the grid proportionately.
The grid input is consistently about 33% of the power made by the panels, if a cloud appears and the output drops from say 5 Kw to 1 Kw the house hold load (according to the inverter software) decreases proportionately.
I.e., at 5Kw from the PV Plant it would show approx. 1.65 Kw coming from the grid. At 1 Kw from PV plant it would show 0.33 Kw coming in from the grid always proportional
The household load is being shown regardless of the actual load as a combination of the power made and the grid input from the grid in a 66% to 33% average.
Hope you can envisage this, I'll attach images. Personally, I think the inverter is configured wrong, when I read the actual KW figure of household usage on the power sensor it reads about what I would expect from the power we are using at the time and bears no resemblance to the inverter software figures.
