Battery measurements for exports and reports are replaced

Plants with battery storage are measured with a new set of values covering the whole storage system down to module and cell level. The previous battery charge, discharge, level, capacity and temperature measurements are no longer offered for exports, reports and dashboards; daily battery figures now come from the new whole-system counters.

Action required: API users, and anyone who built exports, reports or dashboards on battery values: switch them to the new battery measurements. The previous battery charge, discharge, level, capacity and temperature measurements are no longer offered, so an export or dashboard built on them returns nothing. Figures collected under the previous measurements stay in your plant's history.

  • The battery level figure is replaced by state of charge, with state of health and stored energy added.
  • Daily charge and discharge figures are taken from the storage system's lifetime counters.
  • Battery temperature is listed with the environmental values.
  • Values below the whole system — cabinet, module and cell — appear where the equipment reports them.
