6.5.2
Parallel connection
Only wire modules of the same type and performance class. Ensure compliance with the maximum
permissible reverse current provided in the data sheet. In the event of reverse currents (caused by
module defects, ground leakage or shading), modules connected in parallel can also be damaged. In
order to limit reverse currents that occur, we recommend the following fuse variants:
Every conductor needs to be protected against reverse currents from the rest of the system with a
string diode. Within the scope of DIN VDE 0100-712: 2016-10, diodes are no longer permitted as
reverse-current protection.
Usually, each string on the model needs to be protected with fuses (values see 5.) on the plus and
minus sides. Check the calculated value of the fuse in accordance with IEC 60269-6, including the site
and the orientation of the PV system.

PLEASE NOTE!
When installing modules from different product revisions, observe the minimal
permissible limitation of the product revisions used.
