  1. Goodwe MPPT panel split

    TiaanW posted a topic in Solar Power
    Hi, I currently have 10 x 395 PolyPERC panels in 2 serie strings of 5 each on my Goodwe ES5048. I want to expand the DC input to be closer to the max DC capacity of the inverter and have roof space for only 4 more panels. I am hoping to add 4 x 460 Mono panels. Is there a problem with reconfiguring and putting the 10 x 395 on one MPPT and the 4 x 460 on the other assuming the 10 in 1 string won't exceed the max input of the inverter? The reason I am asking is that it seems the 395w will pull down the 460w when on the same string to the least common denominator. So it seems to make sense to group like together however the question is whether the inverter will handle such voltage imbalance between the 2 MPPTs graciously.
