5.4.2 Battery Temperature Sensor
The battery temperature sensor measures the temperature of the connected battery.
This is necessary since the optimum charging voltage for a lead acid battery is heavily
temperature-dependent. Further information is provided in section 11.1 "Charge
Control" (Page 102).
Proceed as follows to connect the battery temperature sensor to the Sunny Island
3324/4248:
The Sunny Island 3324/4248 can only be put into operation once the battery
temperature sensor is connected.
Only use the battery temperature sensor provided with the
delivery.
Do NOT extend the battery temperature sensor cable!
Do not drill any holes in any part of the battery to mount the
sensor.
