Description
-
Battery voltage has
exceeded controller limit.
Controller exceeds
operating temperature
limit.
The device working
surrounding temperature
is too high, and the
controller would stop
charging anytime.
Solar array voltage
exceeds controller rated
input voltage.
Solar array input wires
connected with reverse
polarity.
Battery connection wires
connected with reverse
polarity.
Quick Troubleshoot
Check battery bank voltage for
compatibility with controller.
Ensure the controller is placed
in a well-ventilated cool, dry
place.
Try to lower the working
surrounding temperature.
Decrease the voltage of solar
panels connected to the
controller.
Disconnect and re-connect with
correct wire polarity.

* Note: the missing error codes in the above chart indicates that this controller has no such
error or alarm condition.
12. Error Code Chart 13. Controller Specification
For example, the equalize charge voltage for a 12V FLD (Flooded) battery bank is 14.8V*1=14.8V.
The equalizing charge voltage for a 24V FLD (Flooded) battery bank is 14.8V*2=29.6V.
The variable “n” is adopted as a multiplying factor when calculating parameter voltages, the rule
for “n” is listed as: if battery system voltage is 12V, n=1; 24V, n=2; 36V, n=3; 48V, n=4.
