[latest news] PV connector test about the SUNYO brand and MC brand

PV connector test about the SUNYO brand and MC brand

	SUNYO connector	Stäubli connector	Ordinary connector	Remarks
Use reduce resistance technology	Yes	No	No
Contact resistance	≤0.3mΩ	≤0.25mΩ	≤5mΩ
			≤1mΩ
			≤0.5mΩ
The contact resistance is stablefor a long time	Yes	Yes	No
Protection level	IP68	IP68	IP67	Long-term stability is extremely important to the power station,affecting the return on investment
Rated current	35A	39A	30A
Pass the salt spray test	Yes	Yes	No	important parameters of coastal power stations
Use the return material	No	No	Unknown	Material cost difference, Add secondary materials, it is easy to accelerate aging outdoors, shorten the service life

This test is about the current-carrying load test.

1. The International Electrotechnical Commission (IEC) and the European Electrotechnical Commission (CENELEC) currently do not have relevant standards for photovoltaic modules/system connectors.

2. TUV Rheinland Product Safety Certification Agency (TRPS) has adopted relevant internally established standards for the safety certification of TiV logo products of photovoltaic modules/system connectors.

"2 PfG 1161/01.06"; "2 PfG 1161/05.04"; "2 PfG 1161/04.01"

3. In December 2006, the German National Standardization Organization DIN and VDE launched the draft safety requirements and test methods of photovoltaic modules/system connectors DIN V VDE V 0126-3: 2006-12, this document may be the most authoritative photovoltaic connection in the world at this stage. standard.

4. TUV Rheinland Product Safety Certification Agency (TRPS) currently also adopts this standard for the safety certification of TUV logo products of photovoltaic modules/system connectors.

Group A: Mechanical performance test

Retention of connector contact coupling

Originality Document

Test force: 3 times the normal coupling insertion force specified by the manufacturer (instructions) or 50N plus the normal coupling insertion force specified by the manufacturer (instructions), whichever is smaller, but not less than 20N,

During coupling, the insertion force gradually increases until the above-mentioned test force is maintained for 15 seconds, and the rate of increase of the insertion force during coupling insertion does not exceed 10 N/s.

1. Load current 1A, measure the initial contact resistance R1.

2. No-load insertion and removal 100 times, insertion and removal speed 10mm/s, every 30s interval, no damage to the connector.

3. Contact resistance R2<1.5R1 or ≤R1 +5mQ; 2000V+4 times rated voltage 1min power frequency withstand voltage test...

4. The non-reconnectable connector is subjected to the bending test under the rated voltage and rated current, and the connector with a conductor cross section >0.75mm2 is installed, the hanging weight is 20N, the test equipment is shown in Figure 1; the number of bends is at least 100 times; the test process There is no current interruption during the test; after the test, the cable insulation layer is free from wear and tear, and the broken conductor does not puncture the insulation layer.
