V4.61 controller issue with the shunt.

[anthonyevs]

Hi,
Have been running the latest V4.61 controller with an all in 1 board for over a year niw, but yesterday had an issue.

The controller is showing the shunt as importing 45 amps when its not connected to the inverter and the contactors are off, so its not possible for the controller to be importing to the battery, plus the battery voltage on the controller and shunt are solid at 52v even thought the controller shunt displays as counting ah in and kw importing, when its not.

Ive checked all the wiring and it all seems ok, i`ve examined the components around the shunt terminal on the controller and they all look fine, nothing seems blown.

What could be causing this issue.

For now i`ve removed the shunt from the setup page and operating the battery being controlled via the inverter in lead acid mode.

Any hep greatly appreciated.
Anthony.
