Step 4: Wiring the Inverter

Installing the Battery Temperature Sensor

The Battery Temperature Sensor (BTS) port is for connecting to the Battery Temperature Sensor, which regulates battery charging based on battery temperature. Installing a sensor extends battery life by preventing overcharging in warm temperatures and undercharging in cold temperatures. This port is also considered part of the DC interface (see Figure 2-9).

To install the Battery Temperature Sensor:

1.Pass the end of the Battery Temperature Sensor cable through a conduit hole and insert the Battery Temperature Sensor plug into the Battery Temperature Sensor port.

2.Route the cable to the battery enclosure and connect the ring terminal on the Battery Temperature Sensor directly to a battery terminal (recommended), or use the adhesive backing on the sensor back to attach the sensor to any side of the battery to be monitored.

If using the adhesive backing, install the Battery Temperature Sensor 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.

Note: If other Xanbus connected components supply a BTS or are BTS enabled, it is not necessary to install all of them at once. Only one BTS needs to be installed.

However, if multiple battery-banks are being used, multiple sensors can be installed. In which case, the system will use the highest temperature from all the input as it’s operational parameter.
