WhisperPower Inverter / Battery Charger
Battery Recharge Timer:
The charger will restart a full charging cycle automatically if the float stage is maintained for 7 days.

AC Source Circuit Breaker Function
AC Source Circuit Breaker Setting
230 Vac Models: Selectable Values: 16, 14, 13, 12, 10, 8, 6, 4A (Default: 16A)
This setting limits the total AC current draw from the AC Source during the By-Pass Mode to avoid tripping the
AC Source Branch Breaker. The selected value must be the same or smaller than the rating of the AC Source
Branch 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 or 24V 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 cannot 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.
