Wait for 5 minutes and turn on the battery switch, AC switch, and DC switch. If yes, contact the local power operator. If not, contact the local power operator. If the fault persists, contact your vendor or technical support. If the alarm occurs occasionally, the power grid may be abnormal temporarily. After powering on the device, check whether the output mode set on the device matches the actual cable connection. Alarm Attribute. 1. Possible Cause. If the alarm occurs accidentally, the power grid may be abnormal This document describes the SUN2000-50KTL/50KTL-C1 in terms of its installation, electrical connections, commissioning, maintenance, and troubleshooting. Excessive PV modules are connected in series in the PV string, and therefore the PV string open-circuit voltage exceeds the maximum operating voltage of the device. 14 Power grid exception: The actual grid frequency is higher than the requirement of the local power grid standard. Abnormal Grid Voltage. If the grid-tied point voltage is higher than the allowed range, change the overvoltage and undervoltage protection points after obtaining approval from the local power operator. 2110 Power Control Abnormal at Grid Connection Point. The current at the grid . The power grid experiences If the alarm persists, contact Huawei technical support. Too many PV modules are connected in series in MPPT1 PV string, and the open-circuit voltage exceeds the limit at the current altitude. See full list on instylesolar. Major. If the alarm persists, contact your dealer or technical support. Issue 07 (2024-07-15) Updated 44 2080 Abnormal PV Module Configuration. The device automatically recovers after detecting that the power grid becomes normal. Check whether the grid voltage peak is too high. Cause ID. 2116 DC Input Undervoltage. If yes, modify the power grid overvoltage protection threshold after obtaining the consent of the local power operator. If the alarm occurs frequently, check whether the power grid voltage is within the allowed range. If the device is connected to a TN power grid, check whether the neutral wire is properly connected and whether the voltage to ground is normal. If you consider the wiring to be in order, Contact inverter service: Huawei: 106-113: Abnormal String 1–8 Dec 4, 2018 · If the alarm occurs accidentally, the power grid may be abnormal temporarily. com May 6, 2023 · The power grid voltage is below the lower threshold or the under-voltage duration exceeds the value specified by LVRT. 2113 Invalid Region. If yes, modify the power grid undervoltage protection threshold after obtaining the consent of the local power operator. A-B phase to phase voltage is 466 V, A-C phase to phase voltage is 221 V, and B-C phase to phase voltage is 197 V. The power grid voltage is beyond the acceptable range. BOM numbers of the SUN2000s with user interface boards: 01073021 and 01073021-001; BOM numbers of the SUN2000s with no user interface board: 01073670 and 01073399. If not, adjust the settings based on the PV module model. ) Abnormal Grid Voltage. Alarm ID. If the alarm occurs accidentally, the power grid may be abnormal If the device is connected to a TN power grid, check whether the neutral wire is properly connected and whether the voltage to ground is normal. 30 2051 Abnormal Residual Current. If the alarm occurs occasionally, the power grid may be abnormal temporarily. Check that the battery is enabled, the communications cable and power cable are connected correctly, and the communication parameters are consistent with the RS485 configuration on the device.
