required to allow the battery slope thermal compensation function to be utilized. Additional probes for
individual battery or multiple string monitoring can be added as desired. The highest temperature
measured from all the probes is utilized by the controller. Although many systems come with the
probes factory installed, probes can be added or replaced in the field. The following figure depicts
monitoring all batteries in a single string without the use mid-string voltage monitors. Actual cables
and connectivity may depend on true system connect
Following are basic steps when installing the temperature probes for Thermal Compensation without
Voltage Monitoring.
Step Action
