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.
Definition Trouble shooting
Overload
Reduce load
Low batt. Recharge or replace battery
Check DC cable connections
Check cable cross section as it may be insufficient.
See section 4.3 Protections and automatic restarts for
manual and automatic restart behavior.
High batt.
Reduce DC input voltage, check for faulty charger
High temp.
Reduce load and/or move inverter to better ventilated area
High DC ripple Check DC cable connections and cable cross section.
