Recently added 2 new ECS2900 to existing system, After batteries were added 2 updates were applied. 1 for batteries and 1 for KH8 Inverter. After the upgrade I expected some increase in inverter consumption whilst batteries were equalised. After 4 weeks the Inverer consumption is still very high, upto 4 times the consumption before batteries and updates were carried out. Consumption is approx 5.7kWh when before it was approx 1.3kWh.
Sytem is
Foxess KH8 inverter
5x ECS2900 batteries
Can you post some images that show the consumption, if you go into the app and click on ‘Daily Production’ - it will show a graph that contains the main system sensors (solar, battery discharge, grid import, grid export, battery charge, load, soc) - can you post that graph for a few different days please
See attached some screenshots as requested - three from the last 3 days and 3 from a couple of days before batteries were installed and updates carried out.
Also see screenshots of figures taken from Energy Stats app for some of February (A) before update and some figures from after update (B). Update was carried out on 18/02/2026
