6 FAQs about [Photovoltaic inverters and surge]

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.

Do PV systems need a surge protection system?

PV systems are at high risk of lightning strikes due to their installation in exposed locations and must therefore be protected against surges in accordance with EN 61643-32. To avoid system failures, high repair costs and loss of sales due to surge damage, powerful PV arresters are the best solution.

Why are solar PV inverters so expensive?

Inverters are expensive, but for industrial applications, an even more expensive failure is the cost of downtime. When lightning strikes a solar PV system, it causes an induced transient current and voltage within the solar PV system wire loops.

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.

Can a microinverter protect a home from a surge?

An SPD (Surge Protection Device) installed at the combiner box in residential solar systems with microinverters can protect the home from array surges. An SPD on the main panel can also protect the home from array surges, as well as those from utility power and other internal equipment.

Where should solar surge protection be installed?

For installations with DC cable lengths under 10 meters (33 ft) in commercial and utility-scale systems, solar surge protection should be installed at a convenient point such as at inverters, combiner boxes, or closer to the solar modules.
