TUV-R 7xxyy-01

xx = 17 (Module), 18 (BOS) or 19 (System)

yy = standard number

01 = part number

This numbering system is subject to change.

ANSI/TUV-R Standards Under Development

6

SCOPE:

TUV-R 71730-01 describes requirements for the design qualification and type

approval of PV modules under the effects of inhomogeneous snow loads suitable for

long-term operation in climates where snow is prevalent. These specifications

describe a test method for determining the direct load-bearing capability of PV

modules under these snow conditions.

TUV-R 71730-01: Inhomogeneous Snow Loads

NEED:

IEC 61215/61646: Horizontal, uniform snow load test (5400 Pa)

Supplement to the IEC 61215/61646 snow load test

Field experience in installing and using PV modules had revealed damage

from inhomogeneous snow load displacements at the typical tilt angles

between 30° and 45°

SCOPE:

TUV-R 71830 describes the design qualification and type approval requirements

for microinverters and microconverters for long-term operation in general open

air climates. The standard aims to determine minimum requirements for quality

and reliability of the microinverters and microconverters and to show that they

are capable of withstanding prolonged exposure in open air climates.

TUV-R 71830-01: Microinverters and Microconverters

11

NEED:

Qualification standards for modules exist

Qualification standards for module level power conditioners do not exist

Module level power conversion devices undergo higher level environmental

stresses as compared to central/string inverters (hotter environment on the

back of the module!)

Sample size and stress tests may have to be different as compared to string

and central inverters

SCOPE:

TUV-R 71930 describes safety and general requirements for assemblies of

power conversion systems for utility-scale renewable energy power plants (RE

PCS). The standard defines the minimum requirements for the design and

fabrication of RE PCS for protection against electrical, fire, mechanical and

other hazards. The products covered by these requirements are intended to be

installed in accordance with NFPA 70: National Electrical Code®.
