Hi,
I just start having problems with my setting after a couple of years working fine. I have eight (8) 150W PV connected to get 40V (Voc 22.5V, Lsc 9.05 A) down to a MPPT 100/50 controller. Two series + 4 Parallel. Total PV power 1200 Wp.
The battery bank is 24V. Currently the system has a load around ~200W (~1.73 A).
As you can see in the attached image, the controller reported in that instant ~40V from the PVs, which I think is fine. However, no amps. Eventually, there is activity with peaks up to 20W (0.5A). Image attached.
I double check the voltage of each PV and cable patch conductivity. I discarded the battery fuse, it is working fine. I reseted the controller a couple of times.
I’m starting to thinks the controller is having issues. How would I troubleshoot to discard problems in this component?
Thank you in advance
