Controller Functions
The
C-Series
can be configured to function as three different
controllers:
•
PV Charge Controller (Charge Control mode)
•
Diversion Controller (Charge Control mode)
•
Load Controller (Load Control mode)
Photovoltaic Charge Controller
The C-Series controller can operate as a Photovoltaic Charge
Controller, also called a “series regulator”. Depending on the
model, the controller can regulate up to 60 amps of
continuous photovoltaic (PV) array current at 12 or 24 volts
(C60 or C35 models), or 12-, 24- or 48-volts DC (C40 model)
for charging batteries. This rating includes the NEC required
derating.
If the PV array’s output increases above the rated amp level
due to reflection or “edge of cloud effect,” the controller will
continue to operate until the heatsink reaches a maximum
safe operating temperature. This will take several minutes to
occur, depending upon the ambient temperature involved.
When the heatsink reaches the maximum safe temperature,
the controller will reduce the current, cooling the transistors
and the heatsink.
