4.2 ECO Mode
Set the front switch to ECO mode to reduce the power consumption in no-load
operation. The inverter will automatically switch off as soon as it detects that there is
no load connected. It then switches on, briefly, every 2,5 seconds to detect a load. If
the output power exceeds the set level, the inverter will continue to operate.
The default ECO mode wake-up minimum power is 25 Watt
The default ECO mode search interval is 2.5 seconds
Note that the required ECO mode settings are heavily dependent on the type of load:
inductive, capacitive, non-linear. Adjustment may be needed.

Status
Trouble shooting
Red LED Off
Inverter on
status OK
Red LED On or blinking:
The Inverter is still on, but will shut down when the condition
gets worse. See red LED table for warning reason
ECO mode
If the inverter keeps switching on and off while there is a load
connected, the load may be too small compared to the actual
ECO mode settings. Increase the load or change ECO mode
settings.
Off and waiting Inverter did shut down because of a protection. The inverter
will restart automatically as soon as all alarm conditions are
cleared. See red LED state for the shutdown reason.
Red LED Off
Inverter off
Check the On/Off/ECO switch: it should be in On position or in
ECO position.
Check Remote on/off connector.
Check DC cable connections and fuses.
Inverter fuse blown: the inverter has to be returned for service.
Red LED On or blinking
The inverter did shut down because of a protection. It will no
longer automatically restart. The red LED indicates the reason
for shutdown. Remove the cause and then restart the inverter
by switching it Off, and then back On.
