Hello, friend.
1. Alarm ID2034 indicates that the power grid is overvoltage, the power grid voltage is higher than the allowed range, or the duration of the high voltage exceeds the high voltage crossing threshold.
Solution
If the fault occurs occasionally, the power grid may be abnormal for a short time. After detecting that the power grid is normal, the inverter recovers to normal operation without manual intervention.
If this problem occurs frequently, check whether the power grid voltage is within the allowed range. If not, contact the local power operator. If yes, change the power grid overvoltage protection threshold on the mobile phone app, SmartLogger, or NMS after obtaining the consent of the local power operator.
Check whether the peak voltage of the power grid is too high. If the fault occurs frequently and cannot be rectified for a long time, contact the power grid operator.
2. Alarm ID2039 indicates that the output overcurrent causes the power grid voltage to drop sharply or is short-circuited. As a result, the instantaneous output current of the inverter is excessively high and protection is triggered.
Solution
The SUN2000 monitors external operating conditions in real-time. After the fault is rectified, the SUN2000 recovers to normal operation without manual intervention.
If this alarm occurs frequently and affects the normal power generation of the plant, check whether the output is short-circuited.
3. Alarm ID2040 indicates that the DC component of the output current exceeds the allowed range.
Solution
The SUN2000 monitors external operating conditions in real-time. After the fault is rectified, the SUN2000 recovers to normal operation without manual intervention.
If the fault occurs frequently, contact the PV center to locate the fault. Send an email to the following email address describing your problem and attach your device's SN number.
