I have a system with 3xMultiRS Solar, Pytes 48100R smart batteries (5 pieces). Batteries connected to Lynx Power In and Inverters to Lynx Distributor. BMS in batteries connected to Cerbo and controlled via DVCC. Is there any value for the system to have Lynx Shunt in between Power in and Distributor?
With managed and supported batteries over CAN, a shunt doesn’t add much, unless your BMS is unreliable.
@evgeniy.labunskiy i have observed a couple of things that may influence you. I am not sure about Pytes batteries so this may not apply but in some cases the internal Battery BMS is reluctant to advise small current values which can be a little annoying if you are only drawing very small amounts and are being told that no current is flowing.
Also, in some cases, when the battery is fully charged some batteries can put themselves into a protection mode like into a “float mode” no matter what is supplied by an external charging source. Very clever as the battery can never be damaged by overcharging as the BMS simply open circuits the battery at that point. This means the voltage reported by the internal BMS is different to the voltage on the battery terminals. That is an undersirable situation we think so support having an external shunt as the preferred battery monitor.
Perhaps that is worth considering if Pytes batteries exhibit those characterisitics.
