Silent Mode will begin after the charge routine has finished the bulk/
absorption charge and if the Silent charge has been selected (from Menu
Item 12A Finish Stage). After entering the Silent mode, there will be a
minimum 60 second delay, then the inverter will monitor the battery
voltage to determine if the voltage is at or above the 20A Refloat High
Volts DC setting or if the voltage has fallen to or below the 20B Refloat
Low Volts DC setting.
If the battery voltage has reached one of these Refloat Vdc settings
(20A Refloat High Volts DC or 20B Refloat Low Volts DC) then the
inverter will come out of Silent Mode and begin to maintain the batteries
at the float voltage level.
If the battery voltage falls below the float level, the inverter will use
current from the utility grid connected to the AC1 input to continue to
maintain the float voltage level.
External charging
sources
If some external current (renewable energy source) is used to increase the
battery voltage above the float voltage level, the inverter will use this
excess power above the float voltage requirements to power the inverter
output loads.
If the external current source provides more current that what is needed to
maintain the batteries at the float voltage and power the inverter loads, the
battery voltage will rise.
The inverter will continue to maintain the batteries at the float voltage
level until the 20D Must Float Time Min time has expired and the
current (as read on the 04C INV/CHR Amps AC meter display) has
fallen below the 20C Float Done Amps setting. At this time, the inverter
will return to the Silent mode.
If AC power is lost, after it has returned, the inverter will complete
another Bulk and Absorption charge to the battery and again return to the
silent stage.
Advantages
The advantage of the Silent stage is slightly less power consumption
under most conditions and quieter operation since the battery charger is
off most of the time.
Disadvantage
The disadvantages of Silent charge is the loss of the natural power
conditioning ability of the inverter, the ability to provide the AC load
support (except during the time that the inverter is charging) and a longer
transfer to inverter power from the loss of utility power. These
disadvantages are only present when the inverter is not charging batteries.
Summary
Silent Mode engages on based on DC volts as programmed in
20A Refloat High Volts DC and 20B Refloat Low Volts DC (after 60
second delay)
