June 18, 20242 yr Hello Friends i have An axpert max 7200w with 8 string panles in series at 410w i want to add 10 more panels on the other panel input Can i add those 10 panels in parallel .Here is the pic of panel configuaration. Any help will greatly appreciated thank you.
June 19, 20242 yr Not 10. You'd be at very high risk of blowing the MPPT. Even 9 per side could be pushing it. Simplest is 8 of the same on the other solar input. If you really want the power of the 2 extra panels, then maybe consider 8 of a different panel type. Something like a 500W panel that produces power at a higher current like maybe around 12-13A.

Any help will greatly appreciated thank you. The axpert Max has 2 seperate mppt's and they operate independant of one another. So you can keep your existing configuration as it is for mppt 1, and add the new panels in 5S2P for mppt 2 . This will give you a voc of 247 volts on mppt which is perfect.

June 19, 20242 yr Author So what you saying have two strings of 5 panels in series and then connect the two strings in parallel ?

I have the same config at home, but using 460w vs 405w. So i am slighty overating the spec of 4kw per mppt but it works for me. Yours will be 4050w which is good.
