3.1

Understanding the smart automatic charge distribution

The Omnicharge battery chargers are fully automatic multistage chargers with the ability to
charge three separate battery banks. Omnicharge
battery output to be uniquely configured in order to fit the connected battery. This enables
the possibility to charge a collection of larger and smaller batteries of mixed chemistry by
only one battery charger!
Once the charger is activated, it will check all connected batteries starting at output 1,
followed by 2 and 3. Output 1 has charge priority. But if any battery connected to output 1, 2
or 3 has a voltage below 11.9V (23.8V @ 24V models), Omnicharge
batteries first until 12.5V (25.0V @ 24V models) is reached. After this all batteries are fully
charged to float (or end of absorption in Mode 2) successively, starting at battery bank 1 and
followed by bank 2 and 3. On completion, all three battery banks are moving to a float stage
with a shared voltage level. This voltage level is equal to the lowest float voltage value that is
stored in the setup menu of any of the three battery banks. In this float stage, all battery
banks are still isolated from each other by diode separation.
Battery bank 1 should be connected to the main battery bank that requires charge priority.
On single battery bank installations, do not use outputs 2 and 3.

Night Mode

A unique feature of the Omnicharge
the cooling fan for total silent operation at night or whenever required. This
setting is manually activated by pressing the NEXT (>) button for 3 seconds and
remains active for a period of 12 hours, or until manually deactivated (pressing
NEXT for 3 sec. again). Once active, Night Mode is indicated by the moon and
stars icon on the display. Please note that the charger's output current will be
reduced while in silent mode, leading to longer recharge times.

Charge programs explained

Most standard selectable charge programs, perform a four stage IUoUoP charging process
comprising of a "Bulk" , an "Absorption", a "Float" and a "Pulse" stage. The image below
visualizes the four stage charging process (indicated voltages are typical for a flooded lead
acid battery):
