I keep having an issue where the "Own power consumption" after running a simulation is " 0.0% ", however this not true In the simulation it says I have: PV Generator Energy (AC grid) 996,298 kWh/Year Own Consumption 899971 Down-regulation at Feed-in Point 0 Grid Feed-in 96326 But the own power consumption is 0.0% which makes no sense, is there a fix for this? Thanks
