Connecting PV modules
Connectable solar modules
When selecting the PV modules to be connected to series inverters, note the following:
- Only connect PV modules according to IEC 61730 Class A.
- Do not ground the PV cables.
- Use suitable cables with the largest possible cross-section for connecting the PV modules!
INFO
Use flexible and tin-plated cables with double insulation according to EN50618.
We recommend a cross-section of 6mm². Please observe the specifications of the plug manufacturer and the technical data for the inverter.
- Per MPP tracker:
- Only connect PV modules of the same type to an MPP tracker, i.e.:
- same manufacturer,
- same type,
- same performance,
- same size.
Different module types, sizes and connected loads and also a different number of PV modules can be connected to different MPP trackers.
Make sure that the maximum input current (IDCmax) per MPPT and the maximum DC current per DC plug (IStringmax) are not exceeded in the process.
