Customer ServiceI saw on VRM app that there is alarm about high battery voltage and high dc ripple which may cause my system to restart few times repetitively.
Customer ServiceThere''s a special case of a low dc voltage alarm: an EOD (End-of-Discharge) alarm. This is usually set at the factory to alarm when the battery voltage decreases to 1.75 VPC (for lead-acid) or 1.05 VPC (for NiCd), but you can adjust it to suit your application. This alarm is particularly important for lead-acid batteries to prevent over

Customer ServiceThe battery once again gave a low voltage alarm while about 80% SoC, causing the inverter to restart. There is clearly something wrong. My best guess (based on many informed opinions) is a serious BMS firmware bug or design flaw. It could also be severely unbalanced cells, or a faulty cell. BSL is apparently working on improving the firmware

Customer Service1. The DC bus voltage of the battery is low. 2. The battery DC switch is OFF. 3. The battery cables are not correctly connected. 1. Turn off the inverter AC output switch, inverter DC input switch, and battery DC switch, and wait for 5 minutes. 2.
If the ventilation and ambient temperature are normal, contact your dealer or Huawei technical support. The fuse of the battery power control module is blown. 1. Turn off the inverter AC output switch, inverter DC input switch, and battery DC switch, and wait for 5 minutes. 2. Replace the fuse of the [Battery-1/2] power control module. 3.
Therefore, the detection of abnormal changes in battery voltage can be used to detect faults in advance. However, the battery voltage presents nonlinear and time-varying characteristics, so the analysis of the abnormally sharp challenges hidden under the voltage can be challenging.
Turn on the battery DC switch, inverter AC output switch, and inverter DC input switch in sequence. If the alarm persists, contact your dealer or Huawei technical support. The positive and negative terminals are reversely connected when the battery power control module connects to the inverter. 1.
Alarm severities are defined as follows: Major: The battery shuts down or some functions are abnormal due to a fault. Minor: Some components of the battery are faulty but the battery can still work. 1. The DC bus voltage of the battery is low. 2. The battery DC switch is OFF. 3. The battery cables are not correctly connected. 1.
1. Check the ventilation and whether the ambient temperature of the [Battery-1/2] power control module exceeds the upper threshold. 2. If the ventilation is poor or the ambient temperature is excessively high, improve the ventilation and heat dissipation. 3.
