1 Scope and object
1.1 Scope
This part of IEC 62109 applies to the power conversion equipment (PCE) for use in Photovoltaic (PV) systems
where a uniform technical level with respect to safety is necessary. This standard
defines the minimum requirements for the design and manufacture of PCE for protection
against electric shock, energy, fire, mechanical and other hazards .
This standard provides general requirements applicable to all types of PV PCE. There
are additional parts of this standard that provide specific requirements for the different
types of power converters, such as Part 2-inverters. Additional parts may be published
as new products and technologies are commercialised.
1.1.1 Equipment included in scope
This standard covers PCE connected to systems not exceeding maximum PV source circuit
voltage of 1 500 V d.c. The equipment may also be connected to systems not exceeding
1 000 V a.c. at the a.c. mains circuits, non- mains a.c. load circuits, and to other DC source or load circuits such as batteries. This
standard may be used for accessories for use with PCE, except where more appropriate
standards exist.
Evaluation of PCE to this standard includes evaluation of all features and functions
incorporated in or available for the PCE, or referred to in the documentation provided
with the PCE, if such features or functions can affect com...
