- vrm shows a wrong energy flow into the invertor direction. But, technically there is no invertor connected in the system. Instead, I was expecting the energy flow into the DC Power direction (system is in bulk charge mode with DC load connected through smartshunt 500v).
- Also, i can hear a buzzing high pitch noise from smartShunt 500 which is clearly audible in a noise free environment. is this an issue with my piece?. i can see some of the users reported the same with smartShunt 500 model.
** all negative connections (PV Charger & DC Load) go from smartShunt terminal
Can anyone please shed some light on what is going on here
