I had a Orion Smart installed on my Campervan to charge a Smart Lithium 12V/160Ah battery. My basic vehicle is a 2020 Fiat Ducato with an 'intelligent' alternator. When driving with a constant speed the Orion did not start charging as the input voltage was quite stable at 12.2V and thus constantly below the start voltage of 14V. I then changed the settings so that the Orion will start charging at around 12V input voltage and it did. BUT as soon as the output voltage stabilizes the input voltage drops to around 10.2V, the Orion cuts off, input voltages raises, Orion starts, input drops and so on.
What can be the cause of this? Is there something I can check? I would be really happy if someone had an idea how to correct this!
Thanks a lot, Michael
