SENSITIVITY: This parameter determines how sensitive the Arc fault detector will be 1 being the most
sensitive and 15 the least. This parameter is set to 10 from the factory.
If you experience nuisance tripping you can raise the sensitivity one digit at a time. Follow the
instructions below to make adjustments or disable Arc fault. As a last resort, you may disable Arc fault if
your system cannot work with the arc fault detector.
To change the parameters of the Arc Fault, follow the steps below:
 Press Main Menu
 Scroll to the right or left until TWEAKS is highlighted and press ENTER
 In TWEAKS press the right soft key to get to the BITS menu
 In BITS press the right soft key to get to ARC ADJ
 In this menu use the left and right keys to select the feature to adjust
 Use the up and down arrow keys to change the parameters
In order for the Classic to read the new settings you must power cycle the Classic. Do this by turning the
DC source (PV, Wind or hydro etc.) breaker off. Then turn off the external battery breaker. Than simply
turn the 2 breakers back on starting with the battery breaker.
View Faults and Warning's
The Classic has some helpful safety features including the GFP (Ground Fault Protection) and AFD (Arc
Fault Detector). When one or more faults are detected the Classic will stop outputting power and display
a fault message in the bottom right corner of the home screen (STATUS).
View Logged Data
The Classic logs 380 days’ worth of data in its memory. The data logging in the Classic has two modes
and frequency of data capture.
DAILY HISTORY
Is captured once each day and is saved at night, after 2 hours of no activity when the PV input voltage is
below battery voltage for solar, or in modes that do not necessarily rest at night, like wind or hydro, the
capture will happen once every 24 hours. Data logged each day is kilo-watt-hours, Float time in hours and
minutes, the maximum power output for the day, maximum FET temperature inside the unit, maximum
PV or input voltage and maximum battery voltage for the day.
HOURLY HISTORY
Also referred to as “Short term History” is captured once every five 5 minutes anytime the Classic is not
resting (when it is charging). Data logged every 5 minutes is power, input voltage, battery voltage,
Charging Stage, amps out and kW-Hours.
A time and date stamp is associated with each data entry in both Daily and Hourly history logs. The main
