mode, the charger again transitions to Silent mode. This silent to rebulk
to absorb and back to silent cycle will continue as long as it is required.
ReBulk – When Silent is selected, you must also set the DC voltage
set-point where the charger restarts the Bulk Charge mode. This setting
should be at the lowest DC volts you want the batteries to fall before
starting a new bulk charge. Typically, the lowest DC volts the batteries
are allowed to fall is 12.0 to 12.2 VDC (12-volt systems), 24.0 to
24.4 VDC (24-volt systems), and 48.0 to 48.8 VDC (48-volt systems)
respectively.
Default setting: Rebulk = 12.0V (for 12v inverter)
Ranges: 12.0-16.0 VDC (12v), 24.0-32.0 VDC (24v), 48.0-64.0 VDC (48v)
Why should I use the Silent Stage? Silent mode is typically used when
an alternate charge source is available and able to fully charge or fi nish the
charge cycle after the Absorb stage. A major difference between Multi mode
and Silent mode is that the Silent mode returns to Bulk mode instead of Float
mode. In Silent mode you can also adjust the Rebulk set-point in order to
allow the alternate charge source to provide more of the battery charging.
• SETUP: 10 Pwr Up Always – Allows the inverter to power up and
provide AC power automatically once DC voltage is connected to the
inverter.
Default setting: Pwr Up = NO
Range: YES, NO
What is the Power Up Always feature? Normally, when DC power is
connected to the inverter, the user is required to press the power button—on
the inverter or remote—to turn the inverter on. When the Power Up Always
feature is activated by selecting YES, the inverter is automatically turned
on and starts searching or inverting—depending on the 01 Search Watts
setting. Once the inverter has connected to DC power and is automatically
turned on, the power button—on the inverter or remote—can be used to turn
the inverter on or off.
Why use the Power Up Always feature? Some customers are familiar
with Uninterruptible Power Supplies (UPS) that power-up automatically
when DC power is connected. The Power Up Always feature can be used by
customers that want to obtain the same automatic power-up feature with
which they are familiar.

TECH Menu

The TECH menu button provides access to selections that are used to
assist service technicians in troubleshooting. It provides access to system
information along with a selection that allows all system settings to be
returned to the original factory default values.
• TECH: 01 Temperatures – Displays the various temperatures measured
throughout the system. Rotate the SELECT knob to scroll through these
temperature readings. The following read only temperature displays are
available:
BTS: Displays temperature of the inverter's Battery Temp Sensor
(BTS)—if one is connected to the battery bank.
Tfmer: Displays temperature of the main power transformer (Tfmer)
inside the inverter.
FETs: Displays temperature of inverter's Field Effect Transistors (FETs).
AGS: Displays the temperature of the AGS temp sensor—if one is
connected. If no AGS is connected, "No Comm" displays.
