PV Charge Control Mode Wiring
The procedure below is illustrated in Figure 2-23 .
To connect the C-Series controller as a charge controller:
1. Connect the PV array’s positive (+) output to the PV
array disconnect.
2. Route another (+) cable from the other end of the RE
disconnect to the
PV GFP .
3. Route another (+) cable from the same switch in the PV
GFP to the terminal marked
PV POS / LOAD in the C-Series
controller.
4. Connect the PV array’s negative (–) output to the
terminal marked C
OMMON N EGATIVES .
5. Connect another negative (-) cable from the other
C
OMMON N EGATIVES to the Negative bus in the DC
disconnect.
6. Route a negative (–) wire from the PV GFP to the
Negative bus in the DC disconnect.
7. Connect a positive (+) cable from terminal marked BAT
POS to the battery disconnect in the DC disconnect.
8. Connect a second positive (+) cable to the other side of
the battery disconnect in the DC disconnect and connect
to the positive (+) battery terminal.
9. Connect the negative (–) battery cable to the negative bus
in the DC disconnect and tighten the lugs.
10. Tighten per torque requirements outlined on page 39 .
Allow a little slack on the cables within the controller and
secure the wiring with strain reliefs.
WARNING: Shock Hazard
PV arrays generate voltage whenever light strikes the surface of the
array. Before connecting the
C-Series controller , cover or
disconnect the array to prevent any current from being generated.
