2.3.2.5 ECO Mode

The energy control operation (ECO) mode is an energy-saving mode that can be configured
on the product's liquid crystal display (LCD) or web user interface (WebUI). In ECO mode,
when the bypass input voltage is within the ECO voltage range, the static bypass switch turns
on, and the bypass supplies power (manual startup is required to ensure that the inverter is in
standby state and the power flow has reached the inverter). When the bypass input voltage is
out of the ECO voltage range, the UPS transfers from bypass mode to normal mode. In bypass
mode or normal mode, the rectifier keeps working and charging the batteries using a charger.
The ECO mode delivers a higher efficiency.
