NOTICE
EQUIPMENT DAMAGE
The charge controller can be configured to produce up to 33.5V (24V system) or 67V (48V
system). This voltage may be damaging to some DC equipment. Before setting any voltage
greater than 60V for a 48V system or 30V for a 24V system, or before selecting equalize
mode, review the specifications for all DC-connected equipment to ensure compatibility
with this voltage.
Failure to follow these instructions can result in equipment damage.
The Custom Settings menu item 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 that the charge controller offers.
You can also adjust the temperature compensation constant for the BTS from the
Custom Settings menu item.
NOTE:
n Setting the battery type to Custom is possible only when the Advanced Settings menu
item is displayed.
n The Custom Battery menu is displayed only when the battery type is set to Custom.
n All settings for configuring a custom battery type are based on the default settings for a
flooded battery type.
The following table describes the available custom battery settings. To access the menu,
go to Advanced Settings > Charger Settings > Custom Settings. The voltage
setpoints are referred to a battery temperature of 25°C (77°F).
