A recent solar panel installation. Inverter in the loft, cable run to distribution board which is also where the household CU is along with isolator switch and seperate RCD. There is also a meter installed as part of the PV installation. The solar ouput is connected in before the main electricity suppliers meter which is also on the distribution board. To work correctly shouldn't the solar ouput be connected to the CU after the main electricity suppliers meter? (Solar live is connected immediately after main line input fuse with nuetral same.)
