I'm using the IR-reader to get the data from my electricity meter, it doesn't have a p1 port unfortunately. It looks that it is showing my normal use from the grid AND the production of my panels. So i get 3500 W when I know my house should be using about 500 W (production of about 3000 W).
Still strange, as I would expect I shouldn't take anything from the grid as I'm producing more than I use, so I'm confused...

Is this due to the difference in readout by a P1 port and the IR port? Or are my panels installed improperly?
