“Absorption Mode: During this mode, the converter output is in the 13.7 Vdc range. This is the normal operation mode. This mode provides the 12 Vdc and current required by the 12 Vdc RV appliances, as well as slow charging the battery.”

“Bulk Mode: In this mode, the output voltage of the converter will switch to 14.4 Vdc range for a maximum of four hours (not applicable to Gel-Cell type of batteries). If the converter cycles between "Absorption and Bulk mode," there could be a shorted battery cell or other issues.”

“three-stage switching power supplies. The converter senses which mode it needs to be in by checking the RV system voltage.”

“Float Mode: In this mode, the converter is charging the battery with a trickle voltage in the 13.2 Vdc range. When the converter senses a demand (by turning on lights), the converter automatically returns to the "Absorption mode."”
