2.2.2.5 ECO Mode
The economic control operation (ECO) mode is an economical working mode,
which can be configured on the LCD or web user interface (WebUI). In ECO mode,
when the bypass input is within the ECO voltage and frequency ranges and other
ECO power supply conditions are met, the UPS works in bypass mode and the
inverter is in standby state. When the bypass voltage is outside the ECO voltage
range, the UPS transfers from bypass mode to normal mode. In bypass mode or
normal mode, the rectifier keeps working and charges batteries using a charger.
The ECO mode delivers a high efficiency.

2.2.2.6 Source-Share Mode
If the UPS works properly and the AC input power of the rectifiers is insufficient,
the UPS transfers to joint power mode. In this case, the power module obtains
energy from both the mains and batteries, and the energy is converted into AC
outputs over the inverter.
