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 15 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.
4.3 Protections and automatic restarts
Overload
Some loads like motors or pumps draw large inrush currents in a start-up situation. In such
circumstances, it is possible that the start-up current exceeds the over current trip level of the
inverter. In this case the output voltage will quickly decrease to limit the output current of the
inverter. If the over current trip level is continuously exceeded, the inverter will shut down: wait 30
seconds and then restart.
After three restarts followed by another overload within 30 seconds of restarting, the inverter will
shutdown and remain off. The LEDs will signal shutdown due to overload. To restart the inverter,
switch it Off, then On.
Low battery voltage (adjustable)
The inverter will shut down when the DC input voltage drops below the low battery shutdown level.
After a minimum delay of 30 seconds, the inverter will restart if the voltages rise above the low
battery restart level.
After three restarts followed by a low battery shutdown within 30 seconds of restarting, the inverter
will shutdown and stop retrying. The LEDs will signal low battery shutdown. To restart the inverter,
switch it Off, and then On, or recharge the battery: as soon as the battery has risen and then stays
above the Charge detect level for 30 seconds, it will switch on.
See the Technical Data table for default low battery shutdown and restart levels. They can be
changed with VictronConnect (computer or app).
Alternatively Dynamic Cut-off can be implemented, see

High battery voltage
Reduce DC input voltage and/or check for a faulty battery- or solar-charger in the system. After
shutting down due to a high battery voltage, the inverter will first wait 30 seconds and then retry
operation as soon as the battery voltage has dropped to acceptable level. The inverter will not
stay off after multiple retries.
High temperature
A high ambient temperature or enduring high load may result in shut down to over temperature.
The inverter will restart after 30 seconds. The inverter will not stay off after multiple retries.
Reduce load and/or move inverter to better ventilated area.
High DC ripple
High DC ripple is usually caused by loose DC cable connections and/or too thin DC wiring. After
the inverter has switched off due to high DC ripple voltage, it waits 30 seconds and then restarts.
After three restarts followed by a shutdown due to high DC ripple within 30 seconds of restarting,
the inverter will shutdown and stops retrying. To restart the inverter, switch it Off and then On.
Continuous high DC ripple reduces life expectancy of the inverter.
