If a BTS is not installed, the voltage settings for charging are based on one of
three temperature settings (Cold, Warm, or Hot) available on the Charger
Settings menu. See “Configuring Battery Characteristics and Battery Charging”
on page 2–3.
If multiple charge controllers or a complete Xantrex XW Power System with
Xantrex XW Hybrid Inverter/Chargers are networked together using Xanbus, then
only one BTS is required per battery bank. All networked Xantrex XW Series
devices share battery temperature information, and you can connect the BTS to a
charge controller or a Xantrex XW Hybrid Inverter/Charger. If more than one BTS
is used within the system, then the highest reported temperature from all of the
units with an attached BTS will be used as the battery temperature for the
temperature compensation value of the battery charge algorithm.
Equalization Charging
The charge controller can provide the battery bank with an equalization charge.
Equalization is a deliberate overcharge designed to return each battery cell to
optimum condition by reducing sulfation and stratification in the battery. The
equalization charge is generally performed only on flooded, vented (non-sealed
or “wet”) lead-acid batteries, as recommended by the battery manufacturer.

CAUTION
BATTERY DAMAGE
To avoid damaging your batteries be sure to read, understand, and follow all
cautions and warnings concerning equalization charging. For more
information, see “Equalizing Batteries” on page 3–12.
Failure to follow these instructions can result in equipment damage.
