Hi Andre, Would appreciate your confirmation on my understanding below. I came up with 2 scenarios: Scenario 1: Capacity: 2 strings of 24 nos 270Wp Table: 2x24 Landscape (2 rows, Up and down) Inverter: SMA Sunny Tripower 12KTL (2 MPPT) My understanding is if I connect 2 strings separately to the 2 MPPT, I can define 6 strings in the electrical loss because it is essentially 6 "sub-strings" due to the bypass diode. And if I connect both 2 strings to only 1 MPPT, then I would have to define only 2 strings in the electrical loss. Am I correct? Scenario 2: Capacity: 2 strings of 24 nos 270Wp Table: 2x24 PORTRAIT (2 rows, Up and down) Inverter: SMA Sunny Tripower 12KTL (2 MPPT) My understanding here is because it is portrait, there are no substrings like in the Landscape case. This is because once the bottom row of cells are shaded, the entire string will be affected electrically. The diode can't help in this case. Therefore, irregardless if I connect these 2 strings to the same/ different MPPT, I should still define 2 for the number of strings for electrical loss. The above 2 scenarios are rather straight forward way of stringing the modules. However, I came across some cases whereby in 2x12 Portrait table (one string one table), the modules are stringed in a U-shape ; or in 2x24 portrait in a double U-shape (two strings are separated into left and right instead) to save the solar cable. In this case, how should I define the number of string for electrical loss then? If in situation where instead of Portrait, the modules are in Landscape but also string in U-shape, isn't it gonna be more complicated? Thanks in advance.
