Battery Temperature Sensor Wiring (DR Models)
Battery Temperature Sensors (BTS) should be placed on the side of the battery. They transmit
temperature information to the charger and adjust the charging rate according to the battery temperature. Up
to four sensors can be connected in a dual inverter system with two charge controllers.
1. Locate the battery temperature sensors and route them down through the conduit in the DC Disconnect
Box to the batteries.
2. Place all sensors onto the side of same battery (located in the middle of the battery bank) to prevent
different charging rates based on temperature variances.
NOTE: Temperature sensor cables are already connected to the inverters and PV controllers (if ordered). The
cables only need be run through the conduit to the batteries.
