One for the electronic gurus.
We have the BCDC1240 installed in our vehicle- and apart from a LED which shows charging (or not)- there is no indication as the the status of the PV panel charge rate or consumption rate.
Question: Would the NASA BM1 be helpful to give a readout on information of what is going on with the system?? And if so, how should it be connected into the REDARC system??
Cheers

A battery manager will show what has gone in and out of the battery so will give a good idea as to the state of charge of the battery. The BMS would generally be installed between the battery and the charge/discharge connections, ie the charge wiring and load wiring connected to one side of the sensing shunt, and the battery to the other.
The BMS itself is connected across the shunt for current measuring and across the
battery for voltage sensing.

Sorry, forgot to add if it is a Redarc integrated system your referring to have a look at their website. I don't believe you can add on to an existing charger though if you have one though I maybe wrong.

All you have to do is put a current shunt (with display) on the negative output from the aux battery.....
