Prerequisites
The system is working in inverter mode.
Context
The UPS is set to non-ECO mode by default. Set the UPS to ECO mode when energysaving 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 will to ECO mode, ensure that the bypass module work sproperly.
Procedure
Step 1 On the LCD, choose System Info > Settings > System Settings and set Working mode to ECO. The information indicating that the UPS works in ECO mode is displayed on the LCD.
Step 2 Set the ECO voltage range.
ECO parameters
Step 3 (Optional) If you set ECO mode in bypass mode, manually start the UPS inverter
NOTICE
After the inverter starts, the UPS still works in bypass mode and the inverter is on standby. If the bypass is not normal, the inverter supplies power immediately. If the inverter is not started,the UPS may be disconnected.
