Hi, I have 2 RS450/100 MPPT with 4 lots of solar panels around the roof on my house, the solar seems a bit low on one tracker but all the others seem fine, but getting high voltage but low amps, the solar panels are run in series so the amps are low but voltage is high. I have enclosed a screen shot.
I usually see this (one or two arrays) drop current but high voltage at the end of bulk start of absorption, what's you SOC?. The system just might not need all of what the arrays can supply.
Hi @davidtudor
Switch between each other those two inputs for the XGWVJ MPPT.
If the low voltage is moving to the other tracker, then that string has a problem - some bad connection(s), some bad panel(s), shading, etc.
Or,
There is no need for additional power (more than those 5500W) and that tracker is throttling.

Hi Alex, i was watching it and the low amp tracker shot upto 5 amp, but now low again, the other 3 trackers are around the same. screen shot again as the sun is moving.
