Hey everyone! I'm working with an Eg4 12000xp solar inverter and using both MPPTs. On MPPT1, I have a 2000W solar array, and on MPPT2, I have a 2500W array. The issue I'm facing is that MPPT2 seems to be limited by the output of the first array. When I disconnect the first string, the second one really kicks up by about 500 watts. I'm curious if anyone has run into this and has suggestions for troubleshooting?

Another thing to try is switching the inputs on your MPPTs and see if the problem follows. That could give you more insight into whether it’s related to the inverter setup or the arrays themselves. Let us know how that goes!
It sounds like you might be hitting a limit due to your battery state or maybe there's a current limitation affecting charging. Check if your batteries are fully charged, or if you're running into issues with not having enough load. If that's the case, the system is probably just producing enough power to meet the battery charge and run your loads. Might be worth testing that out!
I’ll have to do some more testing but this actually might be it.
I’ll give that a shot tomorrow!
