I think what you’re seeing is a rounding error. I have solar as well – so see this screen often. Total usage is what your house is currently using – in your case 6.216kW. Solar is what your array is providing – 3.639kW. And Main is what the net power usage is – so if you have net metering – what is or isn’t going back to the grid – in your case you’re using 2.576kW of grid power. If the Main number goes negative then that’s what’s going back to the grid. I say rounding error as 3.639 (solar) +2.576 (grid) is 6.215 (close to your 6.216 reading).

Thanks for that suggestion – at least it gave me something to chase.
If I changed the multiplier on Solar, then by that reasoning total usage wouldn’t change. However, when I do change the multiplier and the Solar -ve number doubles or triples, the usage goes up accordingly.
In addition, the power company gives me a credit every month, so if I am not producing more than I am using, this would not be the case.
I also still have access to the previous company solar metering (I got the Emporia kit because the previous vendors web app is no longer supported as it uses flash – so I have to use bit of an adobe flash hack with an older browser to check my generation and usage) and again, those numbers are not matching/adding the way Emporia is doing it.
Hello @bearalypse Please keep in mind total usage is calculated off your solar usage and Main usage(net metering). Increasing the value of your solar generation will have a direct and linear impact to your total usage since this is looking at your net metering usage..which is not changing so total usage goes up.
