Top half and bottom half both have (separately) 72 half-cut cells in series amounting to 50 Voc and half the power (200-300watts). Left and right junction box have two busbars one each from top and bottom. Then what is the purpose (connection) of middle junction box?

Hi, thanks for the insight! With half-cell modules is it possible at all to DIY-rewire these cells so they are two electrically isolated cells? I ask this because I use 3 solar cells on a 4-input µ-inverter on my balcony.
