This post was for 10 AWG or smaller wire.
If you have an 8 AWG MC4 connector, more than likely it is actually an Amphenol H4 connector. Exact fit with an MC4 connector, except MC4s are only sold to 10 AWG, and H4s are sold to 8 AWG. The $300 to $400 price is what an H4 crimper is supposed to cost.
I actually had trouble finding any 8 AWG H4s for sale when I was looking.
Well I am just looking to crimp some MC4-like connectors to 8AWG wire.
In my situation 10AWG would be a bit too much of voltage losses. I'll have just one 22.4V VOC pannel (I am going to have two of them connected in series actually, but those are portable design and there will be situations when only one will be used, so counting for a lesser voltage), 7.59A ISC. Wire length should be 30m, which gives me like 6.5% voltage drop, which is too much. Honestly, it's just such a pain: there is 8AWG wire for sale, even pre-assembled with connectors, but there are no crimpers if you want to crimp by yourself.
Wait, I forgot, there are, but they cost more than my pannels.
I guess I'll just go with pre-assembled, but still, I wasn't able to find them in 8AWG
tinned copper of such length, so I'll need to buy a few chuncks to make 30m length. The downside is more connections obviously, which are the weak points. And there are also other circumstances which make this solution not ideal.
The crimper would make things so much easier, but I just won't have much use for it, $300 definitely not worth it for me.
Chinese manufacturers, please make it happen for 8AWG!
