Installing the Inverter/Charger
This guide for use by qualified installers only.
Step 5: Connecting the Battery Temperature Sensor (BTS)
Installing a battery temperature sensor (BTS) extends the life
of a battery by preventing overcharging in warm temperatures
and undercharging in cold temperatures. With a BTS
monitoring the battery temperature, the voltage delivered to
the battery is adjusted according to the battery’s actual
temperature.
The BTS has a self-adhesive backing and attaches to the side
of the battery. A 7.6 m cable is supplied with the BTS.
Mounting Options
You can mount the BTS in one of two ways:
•
Mounting the sensor to the negative battery post allows
the internal battery temperature to be sensed and provides
the most accurate results.
•
Attaching the sensor to the side of the battery using the
self-adhesive backing also provides good results in most
situations.
