The Mariner inverter/charger has a fully functional three-stage battery charger. Anytime an
acceptable (within frequency and voltage parameters) AC source is presented to the unit, it will
charge the batteries connected to it. The On/Off switch on the inverter does not control the charger
portion of the unit. When AC is present the charger will charge the battery bank regardless of the
position of the inverter’s On/Off switch.
AC is fed into the inverter’s AC input and the transformer steps the high voltage AC down to lower
voltage AC. This power is rectified and fed to the battery bank to charge it. The charger is fully
regulated, and protection systems prevent abuse of the battery bank due to overcharge, over-temp,
and/or charger failures

The battery charger in the Trace Mariner inverters charges in three stages - BULK, ABSORPTION,
and FLOAT - to provide rapid and complete charge cycles without undue battery gassing. The
figure below shows how DC voltage and current change with time through the different charge
stages.
