Error Code Chart Code Error E00 No Error E01 Battery Over-discharged E02 Battery Over-voltage E04 Load Short Circuit E05 Load Overload E06 Overheating Description & Quick Troubleshoot No action needed. Battery voltage is too low. DC load will be turned o until battery re-charges to recovery voltage. Battery voltage has exceeded controller limit. Check battery bank voltage for compatibility with controller. DC load short circuit. DC load power draw exceeds controller capability.
Controller Specification 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. 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. Parameter Value Model No.
