I have recently fitted a Votronic B2B which came with a temp sensor to optimise charging of the batteries ( including lithium). I am planning to get the Votronic Duo MPPT 250 which can be fitted with the same sensor but doesn't come with it (so will cost me more). Would it be possible to use the one sensor but split the wires so that they go to both the solar controller and the B2B ( they will be adjacent to each other)? Ie in parallel.
Below is an extract from the Votronic Duo manual which may help someone (but does help me as I don't know much):
The solar controller recognizes automatically a missing sensor, cable break or short-circuit of the sensor lines, as
well as unreasonable measuring values. In that case, it will switch automatically to the usual charging voltage
rates of 20 °C / 25 °C being recommended by the battery manufacturers.
Obviously I don't want to risk anything if I move over to lithium ( my 7 yr old lead acids are working okay but I'm aware they won't last forever.) but it would both save money and save me having to route another cable (the grommet is quite tight as it is)
Thanks
Paddy
