Error code
P-11
Description PV array over voltage
Protection level More than 320V
Activation time 200 mS
Case.1 Cause Input voltage of the solar power conditioner exceeds the limited value.
Check Check the voltage of all input terminal of the solar power conditioner.
Action (1) If the input voltage is large than 350V. --The solar power conditioner is in
normal condition. But the input voltage exceeds the allowed value of the solar
power conditioner and it may damage the solar power conditioner. Immediately
turn off the DC breaker and check the PV strings.
(2) If the input voltage is 350V or less. --The solar power conditioner is in
normal condition. But it will not restart until the voltage is 320V or less. Wait
until the sunlight radiates decrease so that the voltage is 320V or less.
If such phenomenon occurs frequently, ask the dealer to check the PV strings.
And study to change the number of series connection of PV modules in
necessary.
Case.2 Cause PV array voltage detector circuit is failed.
Check Check the voltage of all input terminal of the solar power conditioner is correct
of not.
Action If the error message "P-11" appears frequently after confirming the PV array
voltage. Replace a new solar power conditioner.
Error code
E-15 (d-15)
Description Relay sticking
Protection level ---
Activation time 2.4 Sec.
Case.1 Cause Relay is failure.
Check If the error message "E-15" appears frequently after re-setting the solar power
conditioner, the relay is damaged. If this error occurs four times successively,
"d-15" is displayed and the solar power conditioner stops.
Action Replace a new solar power conditioner.
Case.2 Cause Relay voltage detector circuit is failed.
Check If the error message "E-15" appears frequently after restarting the solar power
conditioner, the relay voltage detecting circuit is in abnormal condition. If this
error occurs four times successively, "d-15" is displayed and the solar power
conditioner stops.
Action Replace a new solar power conditioner.
