Battery Temperature Sensor
Feet (10M) of Cable
Applying the proper charge voltage is
critical for achieving optimum battery performance and longevity. The ideal
charge voltage required by batteries changes with battery temperature.
The Battery Temperature Sensor (BTS) allows
the charge controller to continuously adjust charge voltage based on actual
Temperature compensation of charge
voltage assures that the battery receives the proper charge voltage as battery
The entire line is equipped with
Battery Temperature Sensing for increased charging precision.
The BTS sends precise information to
the charger, which automatically adjusts voltage to help ensure full battery
charge depending on the ambient temperature of your battery installation.
When the battery voltage is over 104F
(40C), it will reduce the charging voltage by 0.1Vdc with every degree of
We recommend that you install Battery
Temperature Sensors on all banks to protect your batteries and to provide
optimal charging of each bank.
The Battery Temperature Sensor mounts
on the side of a battery or any other location where the precise temperature of
the battery can be detected such as battery mounting racks.
Important: If the battery temperature
is allowed to fall to extremely cold temperatures, the Inverter with a BTS may
not be able to properly recharge cold batteries due to maximum voltage limits
of the Inverter. Ensure the batteries are protected from extreme temperatures.
The following table describes approximately
how much the voltage may vary depending on the temperature of the batteries:
BTS >122F (50C)
BTS <104F (40C)
104F (40C) < BTS < 122F (50C)
Increases the low voltage shut down
point by 0.5Vdc
BTS >122F (50C)
