ECO MODE
ECO mode can be enabled or disabled by user setting. The default setting is disabled. If
it’s required to have high efficiency performance instead of the high power quality, it’s
better to enable “ECO mode”.
In this mode, load will be supported via Bypass input when utility quality is OK. And the
Line input will still be operated to charge battery and INV module is in standby status
with switch opened. When Bypass input is lost, the system will transfer to line mode or
battery mode. When Bypass input is restored, the system transfers back to bypass mode
again. This ECO mode operation greatly improves system efficiency.

Maintain bypass mode
When the UPS needs maintenance and load needs uninterruptible power, the users can
firstly transfer the inverter to bypass mode, and then switch on maintain bypass breaker.
After that, switch off all other breakers and switches. In this condition, the utility can still
power the load and users can maintain the UPS.
