This afternoon (and it has happened before) I had some strange behavior from my 150/35 MPPT.
Its West facing so I would expect some solid output through out the afternoon. I have a good load and batteries are almost full or full.
My NEast MPPT (150/60) slowly ramped down as you would expect but the West MPPT150 (150/35) went from Max to 0 a few times at regular intervals (see graph). I would expect it to also ramp down like the other.
I also noticed that when it drops off to 0 the battery draw increases to take up the slack… The MPPT then jumps back to 100% after almost a set time and the battery then gets charged back to 100%.
Could this be a temperature issue with the MPPT? Can’t measure that as its not available on the Cerbo.
ESS and DVCC is enabled.
