  • Page 7 1.3.3 Glossary Abbreviation for "Alternating Current” Abbreviation for "Direct Current” Energy Energy is measured in Wh (watt hours), kWh (kilowatt hours) or MWh (megawatt hours). The energy is power multiplied by time. For example, if the inverter operates at a constant power of 4600 W for 30 minutes and then at a constant power of 2300 W for 30 minutes, it would have generated a total energy output of 3450 Wh in that hour and fed it into the power distribution grid.
