C-02: Set Scan Frequency
 This constant is only displayed if P and O or Scan and Hold are selected as MPPT Type (C-01).
 The scan frequency is settable from 1 minute to 4 hours and the factory setting is 1 hour. Press the
UP and DOWN key to increase or decrease the length of time.
 P and O (Perturb and Observe) will run a full scan at the set time interval (frequency) and then do
P and O scans at shorter intervals in between.
 Scan and Hold will run a full scan at the set time interval (frequency) and then hold the resultant
MP until the next interval. This is also settable from 1 minute to 4 hours; factory is 1 hour.
C-03: Set Percentage VOC
 This constant is only displayed if Percentage is selected as MPPT Type (C-01).
 Percentage measures the VOC at the set time interval and calculates the operating Vmp based on
the percentage set. The percentage set point can be from 0 – 100% and factory setting is 80%.
C-04: Set Percentage EveryTime
 This constant is only displayed if Percentage is selected as MPPT Type (C-01).
 When Percentage measures the VOC, the time interval can be set and time is 1 minute to 4 hours.
Factory setting is 1 hour.
C-05: Set Hold Input Volts
 This constant is only displayed if Hold Input V is selected as MPPT Type (C-01).
 Hold Input Voltage will regulate based on the input voltage set (0-240V) for SCC40MPPT and
SCC80MPPT, based on the panel type. The output current will be based on that voltage.
