The system roundtrip efficiency is the overall efficiency of the system in converting AC energy to DC, putting that energy into storage in the battery bank, removing it from the battery bank, and converting it back to AC. HOMER calculates the system roundtrip efficiency using the following equation:
η = ηinv ηrt ηrect
|
where: |
|
|
|
|
ηinv |
= inverter efficiency |
|
|
ηrt |
|
|
|
ηrect |
= rectifier efficiency |
