Safety
These requirements cover inverters, converters, charge controllers, and interconnection system equipment (ISE) intended for use in stand-alone (not grid-connected) or utility-interactive (grid-connected) power systems. Utility-interactive inverters, converters, and ISE are intended to be operated in parallel
with an electric power system (EPS) to supply power to common
loads.
For utility-interactive equipment, these requirements are
intended to supplement and be used in conjunction with the Standard for
Interconnecting Distributed Resources with Electric Power Systems, IEEE 1547,
and the Standard for Conformance Test Procedures for Equipment Interconnecting Distributed
Resources with Electric Power Systems, IEEE 1547.1.
These requirements cover AC modules that combine flat-plate
photovoltaic modules and inverters to provide AC output power for stand-alone
use or utility-interaction, and power systems that combine other alternative
energy sources with inverters, converters, charge controllers, and
interconnection system equipment (ISE), in system specific combinations.
