thingnario automatically filters out disconnected inverters to keep PR calculations accurate.
If an inverter is connected but not producing, it is still part of the system, so we include it in PR.
If an inverter is disconnected (not sending data to thingnario), keeping it in PR lowers the PR artificially, making the site performance look worse than it actually is.
By filtering out disconnected inverters, we ensure PR reflects the performance of ACTIVE inverters only, helping with accurate system evaluation and O&M troubleshooting.
