condition gets worse. See red LED table for warning
reason
●●------
Slow single pulse
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.
●-●-----
Fast double pulse

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.
