Votronic Temperature Sensor.

[MrPG]

Following on from my questions on multimeters which I wanted to use to test an additional solar panel and regulator which isn’t responding to the panel https://www.motorhomefun.co.uk/forum/threads/multimeter.315610/page-3#posts
RoadPro who originally supplied and fitted the Votronic regulator have suggested I need a temperature sensor and are putting one in the post foc to me.
Could someone explain what this actually does? Simply if possible!

Thanks

Paul

The Votronic MPPT charger will vary the charge to the battery depending on the temperature of the battery. The temperature sensor fits to the negative terminal of the battery. If you have got a lithium battery, they should really have fitted a temperature sensor as part of the installation.

Have you got the Votronic MPPT charger manual? It contains a graph showing the effect of temperature on charging.

No I haven’t but I can download it.
Yes I have 2x100A NDS lithium.
The roof panel has its own Votronic MPPT all fitted by RoadPro.
That’s interesting as they suggested this after asking for a picture of the second controller in situ.

In case you can’t find it!

In the Votronic MPPT manual it says (see bullet 3):

Charging Programs for LiFePO4-Batteries:
 The charging regulations of the battery manufacturer are absolutely to be observed!
 An operation of the unit at a LiFePO4 battery without BMS Battery Management System and without equalization charging of the cells (balancing) as well as safety circuit is not admissible!
 A battery temperature sensor must be installed at the battery (screw to the negative pole) and connected at the unit. It serves as protection for the battery!
 If possible, the battery temperature must be kept above 0 °C.
