Does the MultiPlus II 48/3000 ship with a temperature sensor as stated in the manual? My unit did not ship with one but I am not sure where it would connect because the connections also differ from the manual. If it does not connect to the inverter will I be able to connect a temperature sensor to my venus gx unit and is it advisable to do so?
It depends which version of MultiPlusII you have.
The old one (with M6 battery terminals) does not (according to the manual) come with a sensor nor does it have a position to connect it. The manual states that a VE.Bus smart dongle should be used for temperature measurements.

The new one (with M8 battery terminals) does (according to the manual) ship with a sensor and has a terminal block to connect it up to.

The temperature sensor to be used with the Venus GX is this one: https://www.victronenergy.com/accessories/temperature%20sensor%20qua%20pmp%20venus%20gx
Part number: ASS000001000
Note: You do not get temperature compensated charging when the temperature sensor is connected to the Venus GX, it is for temperature monitoring purposes only.
Is it important to get temperature compensated charge? How does it work with the older Multiplus units that need the additional Ve bus smart dongle? Will you be getting the temperature compensated charge with it added or is there a temp sensor also needed additional?
