Common-Ground Photovoltaic Inverters for Leakage Current

In photovoltaic systems, parasitic capacitance is often formed between PV panels and the ground. Because of the switching nature of PV converters, a high-frequency voltage is usually generated over these parasitic capacitances; this, in turn, can result in a common-mode current known as leakage current. This current can badly reach a high value if

6 FAQs about [Classification standards for photovoltaic inverters]

What is the consolidated version of the photovoltaic inverter standard?

The object of this standard is to provide minimum information required to configure a safe and optimal system with photovoltaic inverters. This consolidated version consists of the first edition (2014) and its amendment 1 (2016). Therefore, no need to order amendment in addition to this publication.

How many IEC standards are there for photovoltaic technology?

There are currently 169 published IEC standards by TC-82 related to photovoltaic technology, and work is in progress for 69 more (new ones or revisions). This set of standards is the most broadly used by the scientific community and technicians in research centres and companies.

What standards are available for the energy rating of PV modules?

Standards available for the energy rating of PV modules in different climatic conditions, but degradation rate and operational lifetime need additional scientific and standardisation work (no specific standard at present). Standard available to define an overall efficiency according to a weighted combination of efficiencies.

What are the major IEC PV module certifications?

Following an overview about the major IEC PV module certifications: The IEC61215 covers the parameters which are responsible for the ageing of PV modules. This includes all forces of nature: Climate (changing of climate, coldness, warmth, humidity).

What is a photovoltaic inverter?

inverters, may be supplied by single or multiple photovoltaic modules grouped in various array configurations, and may be intended for use in conjunction with batteries or other forms of energy storage. Inverters with multiple functions or modes shall be judged against all applicable requirements for each of those functions and modes.

What are the requirements for a power inverter?

Inverter should meet the requirements specified in IEEE Std. 929-2000 or other national standard or the interconnecting utility requirements. Phase current imbalance should be less than 5% measured at 50% and 100% rating. Unbalanced phase currents may cause overheating of the utility transformer.
