Problems With Voltage; Problems With Current - Dometic Go Power! DURALITE 100 User Manual

TROUBLESHOOTING
Display Reading: 0
Time of Day: Daytime/Nighttime
Remedy:
Check all connections from the controller to the battery including checking for correct wire polarity. Check that all connections are
clean, tight, and secure. Ensure the battery voltage is above 6 volts.
Display Reading: Full battery icon flashing
Time of Day: Daytime/Nighttime
Remedy:
Overvoltage error. Disconnect the solar controller from the battery and put a draw on the battery (turn lights or a fan on) to drain
the battery.
Reconnect solar panel after a few minutes. Repeat as needed.
Display Reading: Empty battery icon flashing
Time of Day: Daytime/Nighttime
Remedy:
Undervoltage error. Battery is too low to register a voltage to the solar controller. Plug your RV/trailer in to shore power to recharge
battery to above 8V.

9.2 PROBLEMS WITH VOLTAGE

Voltage Reading: Inaccurate
Time of Day: Daytime/Nighttime
Possible Cause:
Excessive voltage drop from batteries to controller due to loose connections, small wire gauge or both.
Remedy:
Check all connections from the controller to the battery including checking for correct wire polarity. Check that all connections are
clean, tight, and secure. Shorten the distance from the controller to battery or obtain larger gauge wire. It is also possible to double
up the existing gauge wire (i.e. two wire runs) to simulate a larger gauge wire.
Further Steps (if required):
Check the voltage at the controller battery terminals with a voltmeter and compare with the voltage reading at the battery terminals.
If there is a voltage discrepancy of more than 0.5 VDC, there is an excessive voltage drop.

9.3 PROBLEMS WITH CURRENT

Current Reading: 0 A
Time of Day: Daytime, clear sunny skies
Possible Cause:
Current is being limited below 1 Amp as per normal operation or there is a poor connection between the solar panel and the controller.
The State of Charge (SOC) screen is close to 100% and the Sun and Battery icon are present with an arrow between.
With the solar array in sunlight, check the voltage at the controller solar array terminals with a voltmeter.
If there is no reading at the controller solar array terminals, the problem is somewhere in the wiring from the solar array to the
controller.
