I have a Flexboss21 and a 280AH Battery connected in a Grid Tie with Backup configuration, which has been on-line since mid February of this year. I have been working on building some data analysis tools using a combination of Access and Excel that use the export data from the EG4 monitoring app. I ran into issues with understanding what some of the categories are in the exported data. Specifically concerning grid import and load (consumption). Google AI was saying the pToUser and pLoad fields only included what the inverter was sending out to Load terminals of the inverter and not the total household loads. So I did a test and turned on my oven which is on my main panel and not my critical load panel and sure enough the consumption watts jumped up. I also verified the pLoad data field jumped up as well. That tells me those to fields are total household consumption (Main panel + Critical Load panel). Is this correct?
One of the things I wanted to get from my charts and data was a way to compare the EG4 data against my utility bill. I received my first bill a few days back and the comparisons are not as close as I would think they should be. I really can only do a direct compare on two data items, Imported power and sold to grid power. The imported power was within 1 kWh from what the Utility reported. However, the Sold to Grid was off by 27kWh's, or 1 kWh per day average. The interesting thing is the EG4 data was less than the utility data... Good for my bill...
Why is the Sold To Grid power logged by EG4 so much lower than what the Utility logged?
A far as I can determine the only consumed data included in the EG4 export data is pLoad. There is no energy Day or All Time data provided. EG4 tracks at least the All Time energy as it is included on the Monitor page. I am doing my own calculations based on the every 4 minute readings. Provides better than nothing data, but the accuracy will not be that good. Why are eLoadDay and eLoadAll fields not included in the Export data?
Final question... In a Grid Tie with Backup configuration, there are two different loads, the Main panel and the Critical Load panel. Is there a way to derive how much each panel is using from the export data? If not, why not?
