Since the last software update, the statistics are incorrect, and nobody has reacted so far. When you look at the graph, you can see that from midnight until 6:00, the system used at least 12 kW from the grid, and later on also more than 6 kW. However, in the displayed statistics, there is no grid import shown between midnight and 6:00.
I checked the data, and it shows that the system stores the correct values and also displays the correct graph. Only the calculation in the statistics is wrong. This is clearly a programming bug, but since we mainly rely on the statistical numbers, the results are misleading.
We should put pressure on Growatt, because the numbers are incorrect. The difference between Growatt’s data and the energy provider’s data is more than 10%.
Please let me know if you are experiencing the same problem.
Thanks.
