Can a PV inverter be installed outside?

There are many inverters for PV systems that can be installed outdoors. In fact, most grid-tied inverters are designed for outdoor use, although most off-grid inverters are not weatherproof and are generally mounted indoors, close to the battery bank.

Should PV inverters be shaded?

Even though PV financial models generally include inverter replacements over the lifetime of the system, designing an installation to prolong inverter life rather than shorten it is the most sensible strategy. Thus, even inverters that incorporate robust outdoor packaging should be kept shaded, even if it means installing an awning over them.

Do solar inverters need a cover?

If that’s not possible, a protective cover can be used to guard it against extreme sunlight exposure. However, it’s crucial to ensure adequate ventilation even with a cover, as inverters need cooling to operate properly. Solar inverters are the heart of any solar energy system.

How do I protect my inverter from lightning?

Lightning strikes can produce overvoltage that can damage your inverter. A lightning protection device can prevent these voltage peaks from reaching your inverter and other sensitive equipment. To protect your system from lightning, you should install a surge protection device (SPD). This goes at the AC and DC side of your inverter.

Can lightning damage a solar inverter?

Lightning strikes can damage inverters and other components of your solar energy system. The added cost of lightning protection significantly outweighs the cost of replacing damaged equipment. Lightning strikes can produce overvoltage that can damage your inverter.

Where should a solar inverter be installed?

If possible, your solar inverter should be installed in a shaded location, out of direct sunlight. A north-facing wall or a garage are good locations in most climates. As discussed, a shaded location is the best, but what if that’s not possible? Here, creating a shade for the inverter comes into play.
