Hi I am looking for advice with regrds to our campervan’s solar system . I changed our mppt controller to a Victron one as I thought our old one may be playing up. So i ordered a Victron Mppt 100/20. I fitted the controller to our campervan which has a 350w solar panel on the roof. All i am getting is the **. Can it be the solar panel has stopped working? Any help would be greatly appreciated…
