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

Good price, sturdy metal, get the job done

Perfect. Absolutely perfect.

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

I needed to separate my solar panels from the cords that run to the battery. Anyone who has ever done this knows you need a tool. This tool was exactly what I needed and it worked perfectly as they send a couple of different sizes which came in handy. The only downside was that the one tool I was using the most (I had a lot of solar panels to separate) broke. I had to stop my project and order another set which came in just a couple of days. That said, the tool was so effective that I ordered this set again to finish my project, also should note that the second set didn’t break. Finished my project.

Very good wrenches for mc4 connectors. Very sturdy being made from metal instead of plastic. Will not fit every mc4 connector but the ones it does fit it works great. It is not the sellers nor fault of the product, it's just they need standard dementions so every mc4 that is made is the same exact size. Therefore, I'm not deducting any stars because the product works exactly as intended.

Fast shipped Works great, probably just need the Riley metal pair- I think they do the same thing (the orange one)

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.
