D Group: Auxiliary Relay 1 - opti-solar SC-50 Installation And Operation Manual

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 measure 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 (0-140V) for
SC-80 MPPT and (0-240V) for SC-160X MPPT, based on the panel type. The
output current will be based on that voltage.
D-01: Set Aux Relay 1 Mode
The Auxiliary Relays are useful for functions such as turning a generator on or
off at low battery voltage or load change, turning on an external fan when battery
temperature increases, or shedding certain loads at specific times. Additional
