Standard for Safety of power converters for use in photovoltaic power systems - Part 1: General requirements
Purchase UL 62109-1
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.
1.1.1DV Modification in accordance with the following:
1.1.2 Equipment for which other requirements may apply
1.1.2DV Modification in accordance with the following:
Add new sentence before NOTE 1. "PV PCE with inputs for other non-PV power sources (not specifically addressed by this standard), shall address the normal and abnormal source specific operating characteristics including but not limited to; voltage range, current range, short circuit current, over-voltage, etc."
