Selecting PV inputs
If the inverter's DC inputs are not fully occupied, distribute the input assignment in accordance with the following tables: Make sure that the maximum input current (IDCmax) per MPPT and the maximum DC current per DC input (IStringmax) are not exceeded in the process:
INFO
Only connect PV modules of the same type to an MPP tracker, i.e.:
- same manufacturer,
- same type,
- same performance,
- same size.
Maximum input current
UDCstart | UDCmax | IDCmax per MPP tracker | IStringmax |
|---|---|---|---|
≤ 250 V | ≤ 1100 V | MPPT 1: 40 A MPPT 2: 40 A MPPT 3: 40 A MPPT 4: 32 A MPPT 5: 32 A MPPT 6: 32 A MPPT 7: 32 A MPPT 8: 32 A | DC 1-2: ≤ 20 A DC 3-4: ≤ 20 A DC 5-6: ≤ 20 A DC 7-8: ≤ 20 A* DC 9-10: ≤ 20 A* DC 11-12: ≤ 20 A* DC 13-14: ≤ 20 A* DC 15-16: ≤ 20 A* |
* With 2 DC strings connected, IStringmax ≤ 16 A.
