Sunway Solar Solar Panel Connector Tool Works For Solar Connectors Assembly and Disassembly,Metal Spanner Wrenches Crimping Tool For Solar PV System Extension Cable Wire Kit- 1 Pair

Very good purchase

Not as I had hoped for. Other reviews state that the tools are metal. The tools I received are plastic and do not even fit the connectors that came in the box (round tooth side). I was also shorted one female connector. I give it two stars because the connectors that I did receive do work and fit snugly together. As for being water tight, I do not know yet. they do have the gaskets and o-rings. Would I buy this again? No Would I recommend this product to others? No Update 7/4/17 ( Happy July 4th ) I now see that the tools are supposed to be plastic in the 8 pair MC4 connector with spanners Kit.. (My bad). The tools you can order by themselves are the metal ones. The company is making it right for the missing connector. Therefore I have updated the stars from 2 to 5 sense it was my mistake on the tools and sense the company's customer service was so fast and kind in replacing the missing connector. So now would I buy this again? Yes And would I recommend this product to others? Yes

If you regularly disassemble MC4 connectors, getting this toolset is a must. It is a cheap, stainless steel kit that will survive the elements and last you a long time. I have a portable solar array using multiple panels that regularly relies on me to assemble and disassemble MC4 connections, and having these metal wrenches has been a godsend - especially when it gets cold out and trying to pinch the MC4 connectors by hand becomes twice as hard. I absolutely recommend this. If you're considering these, just buy them - they won't flex like plastic and they'll last you a long time.

Southern Californian sun was 110 outside, I tried to use plastic disconnects for my panels, and they were so hot just from leaving them in the sun for a few minutes that’s the tines just warped rather than taking apart the plugs. These worked much better. Only problem is now they are searing hot when in use. The fit in finish is pretty much out of the cast or press the big edges knocked off so it’s ugly but they work fine. I’d buy again

Perfect. Absolutely perfect.

Good price, sturdy metal, get the job done

You can very carefully bend the forks to accommodate troublesome connectors that annoyingly seem to be slightly undersized. I have some Hyundai panels whose MC4 connectors do not work with regular tools. The tapered fittings do not compress sufficiently with an unmodified tool. The tool on the right is slightly bent inward - till on left is unmodified. Depending process must be done very very carefully to prevent breakage. Obviously this modification cannot be performed on the plastic ones. But the metal ones worked beautifully with these odd panels as well as my regular panels. A worthwhile purchased for my needs.

The larger square open-ended tool works OK for releasing MC4 connectors. However, it is useless for releasing H4 Amphenol connectors which require a considerably narrower ended tool. The smaller square ended tool is about the right width for releasing H4 connectors. However, it is incompatible with H4 connectors with tabs covering the connector locations. Thus, these tools are only marginally useful.
