Issue 01 (2023-03-20)
The UPS is set to non-ECO mode by default. Set the UPS to ECO mode when
it is required.
In ECO mode, the bypass takes priority over the inverter in supplying power. If
the bypass fails, the UPS transfers to inverter mode.
Both a single UPS and a parallel system support ECO mode which ensures a
higher efficiency.
To avoid frequent transfers between ECO mode and normal mode, do not set
ECO mode when the bypass input is unstable or is sensitive to load changes.
ECO mode is not recommended when the load is less than 10%.
Before setting ECO mode, ensure that the bypass is working properly.
NO TE
If the ECO mode is set when the UPS works in inverter mode, the UPS transfers to the ECO
mode 4 minutes after the setting is complete and the conditions are met.
