I have just set up my campervan system and j am getting a ringing noise from the smart shunt 500a. I have disconnected all loads and and the noise remains the only way to stop the noise is by the shunts power cable to the battery.
I tested the noise and it is around 16000-19000hz so it is very quiet high pitching ringing noise. I added a picture showing the noise hz.
Its a Saturday now so ill call my supplier on Monday but wanted to Know it anyone has an idea what the issue could be other then faulty equipment.
Its a new install so I am more than confident with my connections so I'm leaning towards a faulty smartshunt but j could be wrong
