3. UNDERSTANDING THE UNIT
The DC to DC Battery Charger is a fully automatic multi-stage, multi-input battery charger with the
ability to charge from either an alternator linked to a battery, or via solar power with its built-in
Maximum Power Point Tracking (MPPT) Solar Controller. With two inputs available, the house
battery will be charged from either the engine while underway, or via the solar panels when
stationary. The process to choose either engine or solar is fully automatic and both functions are
controlled from within the unit itself without the need for external relays.
During normal operation the DC to DC Battery Charger will do a full charge cycle to float stage on
the House Battery Bank with ability to choose either GEL, AGM, Flooded, Custom Programmable or
Lithium. Once the float stage is reached the charger transitions to a power supply mode to support
any on-board DC loads.
Multi-stage Charging Process
– GEL, AGM, Flooded & Program Modes
The DC to DC Battery Charger is a fully automatic, set and forget charger. It is designed to quickly
and accurately recharge your deep cycle batteries utilizing charger algorithms that help to
maximize the life of your specialized deep cycle batteries.
The DC to DC Battery Charger features multi-stage smart charging technology that enables the
charger to be connected to your House Battery Bank permanently. With the input of multiple
sources, you can be assured of charging your batteries whenever underway; or when the sun is
shining on your solar array.
As dictated by battery manufacturer recommendations, deep cycle batteries require a multi-stage
charge sequence for perfect, fast and accurate charging. The DC to DC Battery Charger delivers
three primary charge stages:
Stage 1
– Bulk or Boost charge:
The battery is charged at full rated output current of the charger (as per the
setting) until the battery reaches its final charging voltage, known as its absorption voltage. In this
step, around 80% of the battery is recovered as fast as possible.
Stage 2
– Absorption Charge:
With the charger voltage held steady, the remaining 20% of the battery is
replaced with the charger allowing the current to taper off as the battery approaches full charge.
Stage 3
– Float:
In the float stage the charger voltage is lowered and held at a constant and safe predetermined
level. This prevents the battery from being overcharged, yet allows the charger to supply enough
current to make up for the self-discharge losses of the battery, while supporting any additional loads
connected to the battery (such as DC lighting and refrigerators). This stage allows the charger to be
used as a DC power supply.
A full recharge cycle will occur when the House Battery Bank voltage drops to below 12.5Vdc on
DMT1230 , 1250 or 25.0Vdc on DMT2430 .
Lithium Charging Process
The DC to DC Battery Charger has a specific charging profile for Lithium batteries. It has its own
charging voltage and current settings that needs to be set by the user. It also requires the user to
set the charger termination
current (“L” setting) to pass from Absorption to Float stage. Once the
user defined charge voltage is reached, the charger will start reducing the current output and the
charging process will terminate when the charging current drops to the set termination (
“L”) current.
This can take anywhere between 3 to 25 minutes, depending on the capacity (size) of the battery
bank and its initial state of charge. The unit will then act as a power supply to support additional
loads connected to the battery. A bulk re-start will occur when the House Battery Bank voltage
drops to below 13.3Vdc on
DMT1230/DMT1250 or 26.6Vdc on DMT2430 .
