6 FAQs about [Analysis of the causes of damage to photovoltaic inverters]

What causes coupling in DC side of photovoltaic inverter?

There are multiple fault causes coupling in DC side of photovoltaic inverter. The changes of voltage, current and power are derived by fault mechanism analysis. The differences of failure feature are used to locate the fault cause. 1. Introduction

What causes a two-stage PV inverter to fail?

Since the two-stage PV inverter has an intermediate DC/DC link, there is a certain voltage difference between the PV module and DC capacitor, and the fault coupling degree of undervoltage is lower than that of overvoltage fault. According to the fault location, the fault causes can be divided into two types: DC short circuit and sampling error.

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 central inverter failure affect PV power plant availability & Roi?

This paper reviewed several publications which studied the failures of the PV power plant equipment’s and presented that the central inverter failures rate is the highest for the PV power plant equipment’s which affected negatively in both PV power plant availability and ROI.

What if a solar inverter fails?

The failure of the inverter and components has a performance of 99.21%. Photo-voltaic solar plants on-line evaluation for a early analysis is possible, with high accuracy and performance by using data mining classifier algorithms as RC and LMT.
