Battery Temperature Sensor (BTS)
A BTS is provided with each Sine Wave Plus Inverter/Charger . This
sensor can easily be installed in the system to ensure proper charging of
the batteries based on temperature. Installing a BTS extends battery life
by preventing overcharging in warm temperatures and undercharging in
cold temperatures.
If more than one BTS is being used, install them adjacent to each other so
that they all detect a common temperature.
See Table C-4, “Variances in Charging Voltage based on Battery
Temperature” on page C–14 and Table C-5, “Temperature Compensation
Calculation” on page C–14 for additional information.
