Terminology
The following terms are used in this document:
Export: The power injected to the grid.
Import: The power purchased from the grid.
Export/Import meter: A meter that is installed at the grid connection point and
measures the energy/power exported/imported to/from the grid.
Consumption: The power consumed at the site. Consumption power is calculated as
the sum of self-consumption power and import power.
Consumption meter: A meter that is installed at the load consumption point and
measures the energy/power consumed by the site.
Self-consumption: The PVpower consumed by the site and not fed into the grid.
Production: The power produced by the PV system.
Production meter: A meter that is installed at the inverter output or site AC
connection, and measures the energy/power produced by the PVsystem or site.
External production meter: A meter that is used for production metering of 3rd party
generators, or for AC coupling with non-SolarEdge inverters.
Site production meter: A meter that is installed at a SolarEdge inverter output, and
reads the energy produced by all the inverters at the site.
Site limit: The power level (in kW) that the inverter falls back to once an export limit
event is triggered.
