f)
AC Source Circuit Breaker Function
AC Source Circuit Breaker Setting
120 Vac Models
: Selectable Values: 30A, 20A, 15A
(Default: 30A)
This setting limits the total AC current draw from the AC Source during the By-Pass Mode to avoid tripping
the AC Source Circuit Breaker. The selected value has to be the same or smaller than the rating of the AC
Source Circuit Breaker.
NOTE: Depending on Digital Input status, Shore (SPW) or Generator (GPW) limits can be set and used.
Shore (AC in Display):
Setting SPW
Generator (AUX in Display):
Setting GPW
g) Manufacturing Factory Default Function
Factory Default Setting
Select ‘Yes’ to reset all the settings to the preset Factory Default settings.
Note: The setting for battery type is GEL. If another battery type is used, select Yes to set all the parameter
to factory default, then proceed to the battery type and make change to the new battery type.
h) Understanding the Digital Input port
Battery charging must be reduced when output power demand exceeds the current limit set for
the circuit breaker on the input source to prevent this external breaker from tripping. Independent
current limiting settings can be programmed for normal (shore) AC input and for generator. The
limiting value for Generator input may be programmed and applied (GPW) by activating the
Digital Input port (with +12V signal).
In Generator mode, with detected AC voltage, the display changes from ‘AC’ to ‘AUX’.
Without activation of the Digital Input, the programming and application current level for Shore
Power (SPW) is employed.
NOTE: In either mode prevention of Circuit Breaker tripping can not be made when output load
connection exceeds the rating of the respective circuit breaker.
NOTE: when running in current limiting mode for elongated periods, the batteries will not fully
charge.
AC Load on Inverter
Although the Power Inverter can provide high surge power up to two times the rated output
power, some high surge loads like air conditioners, sump-pumps, heavy-duty motors, etc. may
still trigger the inverter protection system even though the load falls within the power rating of
the inverter. A higher power Inverter-Charger is required for these appliances.
