Error
Description & Quick Troubleshoot
E00
No Error
No action needed.
E01
Battery
Over-discharged
Battery voltage is too low.
DC load will be turned off until battery
re-charges to recovery voltage.
E02
Battery
Over-voltage
Battery voltage has exceeded controller limit.
Check battery bank voltage for compatibility
with controller.
E04 Load Short Circuit DC load short circuit.
E10
Solar
Over-voltage
Solar array voltage exceeds controller rated
input voltage. Decrease the voltage of solar
panels connected to the controller.
E14
Battery
Reverse Polarity
Battery connection wires connected with
reverse polarity. Disconnect and re-connect
with correct wire polarity.
E05
Load Overload
DC load power draw exceeds controller
capability. Reduce load size or upgrade to a
higher load capacity controller.
E06
Overheating
Controller exceeds operating temperature
limit. Ensure the controller is placed in a
well-ventilated cool, dry place.
E07
Environmental
Overtemperature
The environment temperature sampled by
the external temperature probe is too high.
*Please contact professions for technical support on additional trouble-
shooting.
The variable “n” is adopted as a multiplying factor when calculating parame-
ter 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.
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.
