− Max. voltage parameter
Upper threshold for the bypass voltage. If the difference between the bypass voltage
and the rated output voltage exceeds this value, the system determines that the
bypass voltage is abnormal and that the bypass is unavailable.
The Max. voltage parameter is associated with the system voltage level. The
default value is 15%.
If the voltage system is 208 V, the values include 10%, 15%, 20%, 25%, and 30%.
If the voltage system is 220 V (380 V in the case of three-phase outputs), the values
include 10%, 15%, 20%, and 25%.
If the voltage system is 230 V (400 V in the case of three-phase outputs), the values
include 10%, 15%, and 20%.
If the voltage system is 240 V (415 V in the case of three-phase outputs), the values
include 10% and 15%.
The parameter is configurable after the inverter shuts down.
− Min. voltage parameter
Lower threshold for the bypass voltage. If the difference between the bypass
voltage and the rated output voltage exceeds this value, the system determines that
the bypass voltage is abnormal and that the bypass is unavailable. The values
include 10%, 20% (default), 30%, 40%, 50%, and 60%. The parameter is
configurable after the inverter shuts down.
− Frequency range parameter
Bypass frequency range. When the difference between the bypass input frequency
and the rated frequency is greater than this value, the system determines that the
bypass frequency is abnormal and that the bypass is unavailable.
The frequency range must be greater than the ECO frequency range. The values
include ± 0.5 Hz, ± 1 Hz, ± 2 Hz (default), ± 3 Hz, ± 4 Hz, ± 5 Hz, and ± 6 Hz. The
parameter is configurable after the inverter shuts down.

You can use the ECO function only if power grid conditions are good and the voltage and frequency
fluctuation is within the specified ECO voltage and frequency range.
