Installing DC Input Power Cables

Selecting DC Input Terminals
The SUN2000 has three DC switches (DC SWITCH 1, DC SWITCH 2, and DC SWITCH3).
DC SWITCH 1 controls routes 1–6 of DC input terminals, DC SWITCH 2 routes 7–12, and DC
SWITCH 3 routes 13–18.
Select DC input terminals according to the following rules:
1. Evenly distribute DC input power cables on the DC input terminals controlled by the three DC
switches.
2. Maximize the number of connected MPPT circuits.
