I see that the Smart Shunt can send voltage and temperature information to the MPPT 100/20 charge controller, but can it send battery charge current that I can then use to set the "taper" setting on the charge controller? I have parasitic loads, so the charge controller would receive invalid charge current information using only its current output without using data from a shunt instead.
Hey @Cpt Pat ,
Absolutely it does that. See this text from the manual, link below:
Current sensing - The measured battery current is used by the charger so it knows the exact tail current at which the absorption stage should end and the float (or equalisation) stage should start. To measure the charge current all charge currents from all chargers are combined, or if a battery monitor is part of the network the actual battery current will be used.
Ps. I moved your question to the general Q&A. As this is standard functionality, no need to put it in Modifications.
Thanks for your answer. Do I understand correctly that the SmartSolar solar chargers will substitute the current data from a Smart Shunt in a VE network in place of the current output from the SmartSolar solar charger itself? I can't find any documentation that indicates that is the behavior.
Thanks for your input on this @mvader (Victron Energy) , however, our testing has shown this is not working.
We logged an issue with this back in Nov 2020 with a response from @mkuiken that it is indeed an issue and it would be resolved soon.

We scan the releases thoroughly and have had no responses to indicate this has been fixed.
Do you have any verification this has been resolved and what version, please?
Thanks
David
