7.4 Problems with Current 2
Current Reading: Less than expected
Time of Day: Day, clear sunny skies
Possible Cause:
(1) Current is being limited below 1 Amp as per normal operation.
(2) Incorrect series/parallel configuration and/or wiring connections and/or wire gauge.
(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 icon are present
with an arrow in between.
(2) Check that the modules and batteries are configured correctly and check wiring connections.
(3) Modules look dirty, overhead object is shading modules or it is an overcast day in which a
shadow cannot be cast. Note: Avoid any shading no matter how small. An object as small as a
broomstick held across the solar module may cause the power output to be cut to almost nil.
Overcast days may also cut the power output of the module to almost nil.
(4) Disconnect one or both array wires from the controller. Take a voltage reading between the
positive and negative array wire. A single 12-volt module should have an open circuit voltage
between 17 and 22 volts. If you have more than one solar module, you will need to conduct this
test between the positive and negative terminals of each module junction box with either the
positive or negative wires disconnected from the terminal.
Remedy:
(2) Reconnect in correct configuration. Tighten all connections. Check wire gauge and length of
wire run. Refer to Suggested Minimum Wire Gauge in Section 4.
(3) Clean modules, clear obstruction or wait for conditions to clear.
(4) If the open circuit voltage of a non-connected 12-volt module is lower than the
manufacturer’s specifications, the module may be faulty. Check for blown diodes in the solar
module junction box, which may be shorting the power output of module.
