6 FAQs about [Photovoltaic inverter safety design solution]

What are the safety measures for a PV inverter?

The safety measures for PV systems are continuously being advanced as photo-voltaics are expanded and further devel-oped. For example, residual current mon-itoring, isolation resistance measurement, and reverse current protection are inte-gral features of an SMA PV inverter.

Are photovoltaic systems safe?

Photovoltaic systems have played a key role over the last decade in the evolution of the electricity sector. In terms of safety design, it’s important to consider that a PV plant constitutes a special system of generation, where the Direct Current (DC) presence results in changes to the technical rules.

Are PV systems dangerous?

Contrary to some misconceptions, PV systems pose less of a risk of fire than your refrigerator or tumble dryer at SMA. Let’s dispel false and misleading information. The facts are these: PV systems are generally safe.

Are solar PV inverters reliable?

Further, it is identified that for a solar photovoltaic (PV) inverter the power module construction intricacy and the complex operating conditions may degrade the reliability of these modules, affecting the functional efficiency of the overall grid-connected PV systems (GCPS).

Why are photovoltaic systems important?

And photovoltaic systems (PV systems) have an important part to play in this. PV already makes a relevant contribution to our power supply. At the end of 2020, there were two million PV systems installed in Germany with nominal capacity of 54 gigawatts (GW).1 Together, these systems generated around 50.6 terawatt-hours (TWh) of solar electricity.

How dangerous are PV systems in Germany?

Approximately 30 percent of all fires in Germany are caused by elect-ricity. So just how dangerous are PV systems? The independent institute Fraunhofer ISE determined that to date, less than 0.006 percent of all PV systems in Germany have caused a fire.3 As such, PV systems are among the safest electrical systems. how rare PV system fires are.
