So its not a system I installed, but one we had installed.
Our setup includes:
4x 210Watt solar panels
multiplus 12/3000smartsolar Mppt 100/50Cerbo GX
4x 100Ah LiFePo4 batteries
So as I understand how it was installed, the Lithium batteries are supposed to be charged by the solar panels, and then they in turn charge the battery that came with my trailer (which is a lead acid). I had to do the programing to get it finalized, I followed the battery manufacturers specifications.
Our system worked for a while back in April, then it stopped out of the blue. Since then, I have pulled down all my panels to test diodes, all came back good. Followed the wires and checked all inline fuses, good. Checked all breakers, good, all wiring and connections labeled correctly and checked. Reset all components to factory settings, let sit for a bit and reprogrammed for my set up. Ran my batteries down to low 12v (12.2v), and nothing still. My displays and info all just say 0-1watts, 0amps and around 22-23volts coming in from my solar and stays in bulk. I am at my wits end right now.
I have gone through so many forum posts and have tried everything on here, as well as various other forums and videos. Below are some screenshots I've taken this morning. Please if you need any more information to hopefully get this resolved please let me know and I'll get what ever I can back here for the community to look at. We are currently on shore power as well to charge the batteries back up, so if anything needs to be done off shore power let me know as well. Thank you all!
*edit* forgot to include my settings
**edit 2: I noticed recently that my ssc battery voltage and my multiplus battery levels are reading differently, 13.5v and 14.3v respectively. Is this an issue as well? If so how do I fix this!
