How is the maximum voltage for PV dc-to-dc converter circuits determined?

The determination of the maximum voltage for photovoltaic (PV) dc-to-dc converter circuits is primarily outlined in the installation manuals provided by the manufacturers of the equipment. These manuals typically contain specific guidelines that consider various factors, such as the design and operational limits of the converter, safety standards, and compliance with the National Electrical Code (NEC). Therefore, following the installation manual instructions ensures that the system is set up correctly and operates within safe voltage levels as defined by the manufacturer.

The installation manual will typically account for relevant variables, such as temperature variations, which may impact the performance and safety of the equipment. This focus on specific guidance provided by manufacturers helps ensure reliable and safe operation of the PV system.
