Victron DVCC - Smart solar charger ignoring max current setting.
I'm building a small test setup that consists of one 100Ah LiFePo4 battery with built-in BMS ( no access to communication ports), cheap "hybrid" inverter, Victron Smart Solar charge controller ( 100/30 ), Victron Smart Shunt ( set as a battery monitor) and RaspberryPi with Venus OS 3.72 acting as a "CerboGX" device. Victron charge controller and smart shunt are connected to the Pi via V.E. Direct ports - bidirectional communication works without issues.
All good and working except one thing - DVCC. My goal is to limit battery charging current to 30A ( combined current from the inverter and charge controller). My understanding was - if a smart shunt detects combined charging current higher than ,let's say, 30A, DVCC would lower Victron charger's current to keep the changing at 30A max.
But it's not working. No matter what limit I set in the DVCC, Victron's charger is charging at its max current set in its settings while charging current measured by smart shunt exceeds the set DVCC limit by a lot. VenusOS says the charge controller is networked and in external control. Everything looks ok but it's not working as I thought it would.
My plan B is to do this in Node Red on the Pi but I'd like to avoid that if possible. Could anyone share any advice on how to troubleshoot ( I have a SSH access to VenusOS )? Thank you!
