The F48 (DC undervoltage auto shutdown) is caused by the voltage falling on the inverter's DC input. The voltage would also crash if the batteries are too small, if the cables are undersized or if the battery terminal connections are not clean.
Learn how to identify and repair common solar inverter faults like overcurrent, undervoltage, islanding, overheating, and faulty communication.
Reduced real time power generation and reduced life span of the solar PV system are the results if the fault in solar PV system is found undetected. Therefore, it is mandatory to identify and locate the type of fault occurring in a solar PV system.
The presence of PV systems results in a 7% higher fault current compared to the case without PV. Next, the same test was carried out considering the PV systems as a current source. As a result, the presence of PV generation results in only 0.5% higher fault current compared to the case without PV.

6 FAQs about [Solar power generation shows undervoltage fault]
What happens if a fault occurs in a solar PV system?
Reduced real time power generation and reduced life span of the solar PV system are the results if the fault in solar PV system is found undetected. Therefore, it is mandatory to identify and locate the type of fault occurring in a solar PV system.
Why does a solar PV system lose power?
In addition, the efficiency drop in a solar PV system is because of the effect of various kinds of faults and failures, which the system suffers. According to the test results conducted in 2010, the annual power loss in the solar PV system is about 18.9% due to its faults and failures .
Does a single phase PV inverter have a fault condition?
In addition to the three-phase PV inverter, in Gonzalez et al. (2018), a single-phase PV inverter (3.2 kVA) is investigated under fault condition when operating with grid-connected functionality. During a fault, the voltage at the PCC of the single-phase PV inverter also reaches 0.05 pu, and the test results are summarized in Table 7.
What is the fault current contribution of a PV system?
It is stated that the fault current contribution of PV systems can vary from 1.1 to 2.5 times the inverter-rated current depending on the type of inverter. The factors that lead to impacts of large-scale PV generation on traditional coordination procedure are discussed in detail.
What are the different types of solar PV faults?
The faults occurring in the solar PV system are classified as follows: physical, environmental, and electrical faults that are further classified into different types as described in this paper. Once a fault is located and detected, an appropriate diagnosis method needs to be used to rectify it.
Does PV insertion affect fault current in residential power distribution networks?
The main objective is to investigate the changes caused in the magnitude of the fault current due to the PV insertion in residential power distribution networks. In both, it is stated that the fault current of each PV system can reach a value of 1.2–2.5 times the PV inverter rated current from 4 to 10 cycles.
