This read-only integer reports accumulated energy consumption for the phase or bank, in tenths of a kilowatt-hour, despite its description referring to it as apparent power. Admins track this cumulative figure over time to estimate the electricity cost or usage trend for a specific phase or bank rather than just an instantaneous reading. A steadily climbing value of 4500, 450.0 kWh, since the last reset tells the admin how much energy that phase or bank has consumed over the tracked period.
