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:
1. 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.
(2) Incorrect series/parallel solar panel configuration and/or wiring
connections and/or wire gauge (for multiple panel systems).
(3) Dirty or shaded module or lack of sun.
(4) Blown diode in solar module when two or more modules are
connected in parallel.
How to tell:
(1) Battery State of Charge screen is close to 100% and the Sun and
Battery icons are present with an arrow in between.
(2) Check that the modules and batteries are configured correctly. Check
all wiring connections.
