See “Default Battery Charging Settings” on page A–2 for default settings for
standard battery types.
Battery Temperature Compensation
When battery charging voltages are compensated based on temperature, the
charge voltage will vary depending on the temperature.
Temperature compensation can be accomplished automatically by using a BTS.
The BTS attaches directly to the side of one of the batteries in the bank and
provides precise battery temperature information.
See “Installing the Battery Temperature Sensor” on page 2–28 for detailed
instructions on how and where to install the BTS.

NOTICE
EQUIPMENT DAMAGE
Check the battery specifications carefully before changing the settings for
bulk, absorption, float and equalization charging. The solar charge controller
is incapable of determining battery type and cannot warn against or disallow
incorrect settings. Incorrect settings may damage the battery or shorten
battery life.
Failure to follow these instructions can damage equipment.
