BULK MODE

This mode is designed with two purposes in mind. First, to quickly restore the energy back into 
the battery. Second, to ensure the lithium cells inside the battery remain balanced. This is  
accomplished by boosting the output voltage to 14.6 VDC and allowing the maximum current  
to flow as required by the loads.
The bulk mode stage could last anywhere from 1 to 4 hours based on the battery and load cur-
rent which is being used. For a full battery, the bulk stage has a minimum time requirement of 1 
hour, which allows the lithium cells inside the battery the time required to “balance”. For  
an empty battery, the bulk stage has a maximum time requirement of 4 hours. If your application 
requires longer than four hours (such as a larger battery bank > 200 Ahr), a simple cycling of 
power will reset the timers. 
As the energy is restored into the battery, the DC system voltage will climb and the current from 
the converter will decrease. If the total amperage draw from the converter reaches a preset point  
(within the one to four hour timer), the converter is designed to drop out of bulk mode.

ABSORPTION MODE

This mode is designed with 1 purpose in mind. This purpose is to provide a safe operating  
voltage for all loads in the RV. This is accomplished by reducing (from bulk mode) the output 
voltage to 13.6 VDC and remaining at this voltage until the power is cycled to the converter.
The absorption mode stage is the default or normal mode of operation, which has no timer  
associated with it. In this mode an output of 13.6 VDC is provided to the DC circuits in the RV.  
This voltage has a long-term history as the acceptable voltage for all loads in the RV, and should 
not place undue stress (nor reduce the longevity) of the lights and appliances in the RV. This is  
not to say that all loads will have an issue with a constant higher voltage; however, some loads 
may have an issue. Please refer to the individual manufacturer’s specifications for acceptable  
operating voltage range of the connected load.
