Installing the Battery Temperature Sensor

Installing a BTS is recommended for optimum charging performance and battery

life extension. If a BTS is not installed and the batteries must operate in hot or

cold conditions, manually adjust the temperature settings to suit the conditions.

See “Configuring Battery Characteristics and Battery Charging” in the Xantrex

XW MPPT 80 600 Solar Charge Controller Operation Guide.

Only one BTS is required per battery bank if multiple charge controllers or a

complete Xantrex XW Power System with Xantrex XW Hybrid Inverter/Chargers

are networked together using Xanbus. All networked Xantrex XW Series devices

share battery temperature information, and the BTS can be connected to a

charge controller or a Xantrex XW Hybrid Inverter/Charger. If more than one BTS

is used within the system, 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.

See Figure 2-8 on page 2–10 for the location of the charge controller’s BTS port.

Dual knockouts on the back and sides of the charge controller are provided for

routing the BTS cable (see Figure 2-4 on page 2–6).

To install the BTS:

1. Remove the charge controller’s wiring compartment cover (see “Removing

the Wiring Compartment Cover” on page 2–5).

2. Remove a knockout from the back or either side of the charge controller, and

then install an appropriately sized strain relief bushing for the BTS cable.

3. Connect the ring terminal on the BTS directly to the negative battery terminal

or positive battery terminal, or use the adhesive backing on the sensor back

to attach the sensor to any side of the battery to be monitored. See

Figure 2-14.

If connecting to the battery terminal, make sure the BTS does not prevent the

power wiring from making the best possible contact with the battery terminal.

If using the adhesive backing, install the BTS on the side of the battery below

the electrolyte level. It is best to place the sensor between batteries and

place the batteries in an insulated box to reduce the influence of the ambient

temperature outside the battery enclosure.

NOTICE

If the sensor cable is damaged and the wires are shorted, the charge

controller registers a battery over temperature fault condition. If the BTS wires

have been cut, the charge controller assumes that the BTS is not connected. A

replacement BTS can be ordered from the manufacturer (part number

808-0232-02).
