Huawei SUN2000 Series User Manual

Terminal Description
The solar inverter has 20 DC input terminals. DC SWITCH 1 controls PV1–PV8
(MPPT1–MPPT4), DC SWITCH 2 controls PV9–PV14 (MPPT5–MPPT7), and DC
SWITCH 3 controls PV15–PV20 (MPPT8–MPPT10).
Figure 5-19 DC terminals
When the DC input is not fully congured, the DC input terminals must meet the
following requirements:
1. Evenly distribute the DC input power cables on the DC input terminals
controlled by the three DC switches. DC SWITCH 1 is preferred.
2. The even-numbered PV terminals are preferred to maximize the connections
of MPPTs.
3. If the number of PV inputs is 11 to 19, connect cables to the odd-numbered
PV terminals from PV1 and PV19, and avoid connections to adjacent MPPTs if
possible.
If the number of PV inputs is 11 to 19, the DC input terminals are selected as
follows.
