Hi dear Victron community!
I have a three phase AC-out-coupled system with Multiplus-II, CerboGX, SmartShunt, Lynx distributor and battery balancers. Battery pack is 48V 600Ah made from 12 pcs of 12V lead acid GEL batteries. Pictures attached. I am interested why I get so different charging values from SmartShunt and Multiplus. The difference is usually around 100 W. And this is 70% difference when battery is full.
The SmartShunt shows correct power when calculated with a simple formula N=UI but the Multiplus power is much higher. Can somebody think of any reason why that is?
Thanks in advance
Karl
