4.7.2.2 Battery Temperature Sensor Connection for Lead-acid Battery
(Optional)
NOTE:
Battery temperature sensor can be optionally used with lead-acid battery for
inverters to accurately detect the battery ambient temperature and adjust
voltage compensation based on the customer-defined coefficient. It is an
optional accessory which may not be provided with the inverter package.
If lead-acid battery is used and battery temperature sensor is needed,
please contact your distributor or Solis sales to purchase individually.
1. Insert the RJ45 terminal end to the CAN port at the bottom of the inverter and fasten
the swivel nut. (Cable length: 1 meter)
2. Fasten the temperature sensor ring onto the battery module. If no suitable fastening
terminal can be found on the battery module, the sensor ring can be attached to the
positive or negative pole of the battery module.
