• 03I: 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: OFF
Range: OFF, ON
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 should 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 VDC 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.
