10.4.2 Renumber the note into NOTE 1. P

Add the following notes:

NOTE 2: The maximum over-current protection rating of a module can be interpreted as the module series fuse rating. A series fuse may be required in the installation of PV arrays. According to subclause 12.2 of EN 61730-1 the maximum over-current protection rating has to be provided by the manufacturer.

P

NOTE 3: A procedure for determination of maximum reverse current is described in EN 50380.

10.8 Fire test

Under consideration.

P

10.9 Reverse current overload Test MST 26 P

10.9.2 Renumber the note into NOTE 1. P


NOTE 2: The maximum over-current protection rating of a module can be interpreted as the module series fuse rating. A series fuse may be required in the installation of PV arrays. According to subclause 12.2 of EN 61730-1 the maximum over-current protection rating has to be provided by the manufacturer.

11 COMPONENT TESTS

11.1 MST 15 Partial discharge test P

11.1.2 Replace the text by:

It is advisable to perform the partial discharge-test before using the back sheet foil in the PV module construction.

P

NOTE: In order to achieve a certain statistical relevance 10 pieces should undergo the test. The size of the specimen depends on requirement originating from the test apparatus.

P

11.1.3 Add the following sentence:

The geometry of the electrodes shall be in conformance with EN 60243-1.

P

11.1.4 In item a) add the following notes:

NOTE 1: Any voltage below maximum systems voltage can be used but the test should start at zero voltage because it may happen that maximum systems voltage is not stated or unknown.

NOTE 2: When increasing the test voltage partial discharges may appear periodically. In that case, the inception voltage is the test voltage at which permanent discharges occur for a duration of at least 60 s.

P

In item b) add the following notes:

NOTE 3: Because partial discharges can disappear periodically, partial discharges at extinction voltage should stay below 1 pC for minimum of 60 s

P

In item e) replace “Uoc” by “Voc” P
