It’s also an essential part of a well-installed system, as the moderate investment PV commissioning entails facilitates future operations and maintenance.

What is a commissioning inverter?

Many incentive programs, certification entities and installation manuals use the term commissioning generically to describe a set of start-up or closeout pro-cedures. In this informal context, a system installer might verify field connec-tions and ac and dc voltage levels before “commissioning” an inverter.

Do PV systems need independent commissioning & verification?

Every project pursuing LEED certification is subject to independent commissioning and verification require-ments. Many financial backers of large PV systems require independent third-party commissioning to validate their investment.

Do you need a third-party commissioning agent for a PV system?

Many financial backers of large PV systems require independent third-party commissioning to validate their investment. The commissioning agents responsible for gen-erating this third-party report represent the system owner rather than the installer.
