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.
11.3 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
poor connection between solar array and controller.
How to tell:
1. The State of Charge (SOC) screen is close to 100% and the Sun
and Battery icon are present with an arrow between.
2. With the solar array in sunlight, check the voltage at the
controller solar array terminals with a voltmeter.
3. 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.
Remedy:
Check all connections from the controller to the array including checking
for correct wire polarity. Check that all connections are clean, tight, and
secure. Continue with the solutions below for additional help on low
current readings.
Current Reading:
Less than expected
Time of Day:
Daytime, clear sunny skies
Possible Causes:
(1) Current is being limited below 1 Amp as per normal operation.
