3.0 Setup
•
SETUP: 11 Bulk Always
– When this setting is turned ON, the charger
automatically goes into the Bulk charge mode each time AC is connected to
the inverter’s AC input.
Default setting:
Bulk Always= OFF
Range:
ON, OFF
Info:
The inverter has an internal two-minute timer that monitors
the AC input source. If the AC input source goes missing and returns
within two minutes, this timer forces the charger to return to the
previous charge mode. This is done to prevent battery over-charging.
If the “Bulk Always” setting is turned on, it will not override this
internal two-minute timer.
Why would I use the “Bulk Always” feature?
Normally, when an
AC source is connected to the inverter’s AC input, the inverter makes a
decision on which charge mode to enter based on the battery voltage level.
If the battery voltage is at a high level (>13.0 for 12-volt inverters, >26.0
VDC for 24-volt inverters, or >52.0 VDC for 48-volt inverters), the charge
automatically goes into the Float charge mode to keep from overcharging
the batteries.
However, some battery types (i.e., Lithium) normally rest at a high voltage
level. With these battery types, the charger would always go into
fl
oat charge,
which may not allow these battery types to be fully charged. Enabling the
Always Bulk
setting will force the charger to automatically go into the Bulk
charge mode and go through a full charge each time AC is connected to the
inverter’s AC input.
• 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.
