ERROR MESSAGES
Caution! Please do not open the controller or attempt to replace components when troubleshooting.
Improper maintenance can be hazardous to the user and the system.
If the controller detects errors or unauthorized operating states, it shows error codes on the display.
Error codes can generally be differentiated, whether there is a temporary malfunction, e.g. regulator
overload or a more serious system error that can be remedied by appropriate external measures.
Since not all errors can be simultaneously displayed, the error with the highest error number (priority) is
displayed. If several errors are present, the second error code is displayed after remedying the more
significant error.
The following meaning is assigned to the different error codes:
1.
Meaning: Battery reverse polarity warning
Remedy: Reconnect battery correctly.
2.
Meaning: Battery Voltage (Too high or too low)
Remedy: Check battery voltage it might be too low or too high, possible recharge battery
manually. If battery can’t be recharged, Replace battery & re-check.
3.
Meaning: Module current too high.
Remedy: Reduce the input current (module power) to <30Amps.
