6 FAQs about [AC and DC protection for photovoltaic inverters]

Does a PV inverter have overvoltage protection?

The inverter is manufactured with internal overvoltage protection on the AC and DC (PV) sides. If the PV system is installed on a building with an existing lightning protection system, the PV system must also be properly included in the lightning protection system.

Why do PV farms need inverters?

PV farms are comprised of very sensitive equipment that needs expansive protection. Because PV farms create direct current (dc) power, inverters (which are necessary to convert this power from dc to ac) are an essential component to their electrical production.

What type of protection does an inverter have?

The inverters are classified as having Type III (class D) protection (limited protection). Varistors in the inverter are connected between phase and neutral cables, between neutral and PE cables, and between PV plus and PV minus terminals.

How do I protect my PV system from voltage surges?

To prevent high energy from passing through electronics and causing high voltage damage to the PV system, voltage surges must have a path to ground. To do this, all conductive surfaces should be directly grounded and all wiring that enters and exits the system (such as Ethernet cables and ac mains) be coupled to ground through an SPD.

Why do we need a solar PV system?

Over the last 50 years, solar PV systems have evolved into a mature, sustainable and adaptive technology. The unique nature of PV system power generation necessitates the need for new and effective electrical protection products for overcurrent, overvoltage and isolation events.

How do I protect my inverter from voltage surges?

Conductors spanning long distances in the system will expose equipment to significant voltages.  Surge protection should be placed at the service entrance to primarily protect the utility side of the inverter from damaging transients.
