Import active energy : it measure the total positive active energy
Export active energy : it measure the reverse active energy , such as solar
power generation , reverse wire connection , some power generator working .
Normally, the total active energy=
| Import active energy | + | Export active
energy |
Contrast active energy : it is used for contrast the kWh running with the
power company meter or other kWh meter .
