Instruction Manual

Configuring Battery Characteristics and Battery Charging
975-0400-01-01 Revision H 3–9
This manual is for use by qualified personnel only.
The Custom Battery menu allows you to adjust charging and equalization voltage
for lithium ion and other specialty batteries whose specifications fall outside of
the default settings for the battery types the solar charge controller offers.
You can also adjust the temperature compensation constant for the BTS on the
Custom Battery menu.
The following table describes the options available on the Custom Battery menu.
Important:
• Setting the Battery Type to Custom is possible only when advanced menus
are displayed.
• The Custom Battery menu is displayed only when the Battery Type is set to
Custom.
• All settings for configuring a Custom battery type are based on the default
settings for a Flooded battery type.
