Parameter AC Input Power Boost
Default Value Off
Description AC Input Power Boost temporarily assists weak AC input sources when the connected load needs more
power than available from the grid or generator. This is accomplished by running the inverter in parallel
with the AC input source. The inverter can add power up to it’s nominal output power rating assuming
the battery is healthy. This parameter can be set On or Off.
Configurable by DIP switch (DIP 7) and Dashboard
Parameter Ground switch
Default Value Enabled
Description The ground switch is an internal relay that automatically connects AC output Neutral (N) to Protective
Earth (PE = chassis) in inverter mode. This enables the use of a ground fault circuit interrupter (GFCI) at
the AC output of the Inverter Charger Combi. When a non-grounded (floating-) output is required, this
Parameter can be disabled.
Parameter AC input fail sensitivity
Default Value Normal
Description This parameter can be set to Very Low, Low, Normal, High and Very High. The value of this Parameter
decides how fast the Inverter Charger Combi detects a signal fail at the AC input. The lower settings are
resulting in a slower AC input source → inverter transfer time, while the higher settings result in the
fastest transfer times. The settings Low and Very Low can be used when the AC input signal is distorted
or unstable, which could be the case when a small generator is used. The settings High and Very High
can be used when the Inverter Charger Combi is connected to a solid grid or quality generator. The
factory setting Normal is a good compromise, which still results in a fast AC input source → inverter
transfer time of less than 5ms, while being reasonably immune against distorted AC input signals.
Parameter Battery type / Charge program
Default Value Liquid-acid
Description The default charge program liquid-acid is compatible with typical flooded type batteries, but can be
used for other types of lead-acid batteries as well. Please make sure that you always check if the
Inverter Charger Combi charge program settings, are compatible with the used battery! The AGM charge
program absorption voltage is 14.4V and the float voltage is 13.2V . Other selectable charge programs
are GEL, AGM1, AGM2, and 4 different types of LiFePo batteries. For further charge program information,
please see chapters 3.2 and 5.1.
Configurable by DIP switch (DIP 4, 5 and 6) and Dashboard
Parameter Charge current limit
Default Value 100 %
Description This parameter sets the maximum charge current in percent. This value can be set with DIP switch(es) or
by Dashboard (from 10% to 100%). You should set this parameter to a lower value when the connected
battery is too small and cannot handle the maximum charge current, or when you wish to (temporarily)
reduce the charger current share, in the total amount of current flowing through the AC input of the
Inverter Charger Combi.
Configurable by DIP 2 (ICC 1600 SI-N/60A), DIP 2 and 8 (ICC 3000 SI-N/120A) and Dashboard
