Known Issues
The energy counters for battery energy import (charging) and export (discharging) will reset to zero when used with LG batteries, which can cause unreliable data collection or lost statistics. These data points are documented as "Lifetime Import/Export Energy Counter" which means they should never reset to zero, however LG batteries do not provide lifetime charge/discharge data.
There is no fix for this issue since it is a hardware (battery controller) issue. SolarEdge Energy Bank batteries have been reported to use lifetime counters correctly.
Starting with Release v2.2.7-pre.5 (PR #177) an option was added to allow battery energy counters to reset to zero. The default is disabled which assumes the proper behavior for a lifetime energy counter. Enabling this option may be required if you are using an LG battery.
