Choosing a proper location is a crucial step in a successful installation. Today’s solar equipment should last up to 20 years, and location plays a role in that lifetime. Although many inverter warranties are not voided by installing in direct sunlight, it is best practice to install in a location that provides the cleanest, coolest setting possible. In the end, inverters are power electronics. Power electronics will always perform better by not derating on hot days, and their components will last longer in the shade.
Positioning of the inverter is also important. Choose a position that allows easy access for later servicing or repair. The standard installed rating for an inverter should be NEMA 4X because then the inverter is well-rated for harsh conditions if the location doesn’t have a convenient, shady ease-of-access point.
Wiring and mounting
To keep costs low, keep wiring and mounting simple. Inspectors will scrutinize your installations less if they see wiring that is clean and well-organized. Wiring differs with all inverters, but keep in mind that easily accessible compartments are crucial.
Product familiarity is another key aspect in successful installations. As the solar industry evolves and the NEC code changes, an installer should know the latest inverter innovations. Not only are inverters becoming more ergonomic and sleekly designed, manufacturers like Fronius have made commissioning more streamlined and easy.
It’s also important to frequently read the most recent equipment manual. Procedures can change as manuals are revised. Understanding changes are critical as the PV market progresses. Updating your equipment knowledge can be as simple as reading or re-reading the equipment manual over time.
Installers are encouraged to attend manufacturer trainings. Information can typically be absorbed faster and more concisely with personal interaction. Installers can host training sessions on a manufacturer’s product in their local facility or attend trade show event trainings. Equipment manufacturers are eager to help customers with technical information and design and strategic implementation of their special and legacy products.
Manufacturers also offer updates through email campaigns and newsletters. Stay in the know with news directly related to NEC code, jurisdiction application and product updates through manufacturer newsletters or email campaigns.
