Creating A Lithium Charge Program With A Float Stage - tbs electronics Omnicharge Solar OCS 100-20 Owner's Manual

If any of the standard selectable battery
types does not fulfil your requirements, there
is a possibility to create your own battery
type or charge program.
For this you need to select battery type
Custom Lead if you have a lead based battery
installed, or Custom Lithium if you have a
lithium based battery installed.
Once selected you will see that all available
parameters can now be edited. In the app
each parameter is explained with text below
the button. Please note that only for lead
based batteries you can set the Nominal
Battery Voltage to Auto. For Lithium based
batteries, you must select a nominal voltage
manually.
You will also notice that when Custom
Lithium is selected, there are a lot less
parameters to edit since a float stage and
equalization are not possible for Lithium, as
well as temperature compensation of the
charge voltage. When you do wish to have a
float stage for your lithium battery, please
see chapter 3.2.1.
When the desired custom battery type has
been edited, please press the back button
and the app will ask you to save these
settings or not. Press 'Save' and the charger
will be updated.

3.2.1 Creating a lithium charge program with a float stage

As explained above, as standard an Omnicharge Solar charger does not offer a float stage for lithium
batteries. If desired however, there is a way to still create a charge program with float for a lithium
battery.
For this please select the Custom Lead battery type in the setup screen and use the following
parameter settings:
• Battery Type → Custom Lead
• Nominal Battery Voltage → select a voltage manually, do not choose Auto
• Charge Voltage → Enter the desired charge voltage
• Absorption Time → Enter the desired absorption time
