5.4 Transferring to Bypass Mode

Before shutting down the inverter, ensure that the bypass is normal. If the bypass is not
normal, after the inverter is shut down, the UPS supplies no power, and the loads shut down.
Shut down the UPS inverter. Shut down the inverter on the LCD or WebUI, and the UPS
transfers to bypass mode.

Issue 03 (2020-04-27)
If the inverter is shut down when the input voltage or frequency exceeds the specified threshold, the
UPS supplies no power, and the loads shut down.
The UPS is set to non-ECO mode by default. Set the UPS to ECO mode when energy
saving is required.
In ECO mode, the bypass takes priority over the inverter in supplying power. If the
bypass is disconnected, the UPS transfers to normal mode.
Both a single UPS and the parallel system support the ECO mode for higher efficiency.
To avoid frequent transfer between ECO mode and normal mode, do not set the 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 transferring the UPS to ECO mode, ensure that the bypass module works
properly.
