This is a good quality cable, my 10 gauge was getting hot coming from an mppt controller so I bought this and problem solved.

These are decent quality cables. In general, I'm not a fan of having separate positive and negative cables because they're much harder to manage but they are less expensive this way. Hard to beat for the price

I ordered this cable to allow me to place solar panels on the roof of my steel building with 12’ side walls and it works great. I was able to run the cable under the eave and down to my work bench where I have multiple battery chargers. The cable is well made and works great. I am not an electrician or a solar power expert so I may not be the best judge of such things and I can’t provide any performance type numbers. However, I am very happy with this cable.

Es exacto lo que pedíBuenas calidad

Un buen servicio

Seems a little heavier then my last 10 wire and flexible enough for my setup, takedown movable camper setup.

Good extension cables for solar panels. 10 gauge is standard for most panels and these are rated for outdoor use that you want. Some may find shorter lengths like 3 foot long ones of little use, yet I've set up some 12V panels in series to be like a 24V and the 3 foot sections brings the connector from one close to the other for a run to controllers etc. FYI I've tried some portable panels using cheaper 14 gauge wires for my ~5 amps expected (over a 20 foot run) and got some power like 4A charge to the battery, but then I swapped out for a 10 gauge cable leaving everything else and got 5 amp charge. So that shows going with better wires can give you 20% more power where it may cost a bit more up front, but will be better in the long run. Some MC connectors have release devices built-in, but these don't (needing a release tool for disconnecting if needed).

Summary: When it comes to buying wire/cable, there are lots of variables, so doing some homework is warranted. Aside from the "what size wire do I need", here are some other considerations: 1) pure vs. cladded wire, 2) jacket material (PVC, silicone), 3) single or dual (or more wires, 4) indoor/outdoor. Most of the wire I have reviewed has been used in extending a solar panel installation for optimal placement.General Observations: Stranded wire will always be more flexible than solid single conductor (such as house wiring). For most applications, having some flexibility is desirable for ease of installation. For power transmission, pure vs. cladded is the preferred option, but will cost more. For outdoor or direct bury applications, you will want to select a suitable jacket material. I have left silicone wire out in the sun for a month, and it has faded (which is why UV rated jackets are desired in those applications).MOOKEERF Observations: This one specifies a XLPE/XLPO jacket (briefly, it's newer than PVC, and an Internet search will give you the added benefits; generally more abrasion resistant and the lack of chloride is more environmentally friendly). This one is offered in 10 AWG (I order 10AWG for all solar/PV projects). A 2x50' length is $60, so the cost per foot is $0.60/foot; and a 2x100' length is $110, so $0.55/foot. The ends are not terminated and MC4 connectors are included (you will need a crimper). MOOKEERF offers 120 products, some are duplicates and most are solar/pv related, and also coax cable related, and have decent reviews. Overall rating this one 5-stars (specialty cable manufacturer, value price point).Recommendations: Here are some considerations when sizing the wire gauge for your application: 1) the thicker the wire (lower AWG number), the lower resistance, and more efficient; 2) the downside to thicker cables, is it's heavier, and sometimes less flexible; 3) higher voltage will lead to insulation breakdown (these are rated for 600 VDC). For the jacket material: 1) silicone is more expensive than PVC; 2) silicone has a much higher working temperature range; 3) silicone is more flexible (wire gauge and type contribute more though). Silicone jacket is soft and tears easily. Typically, with previous 2-wires I have used (especially PVC), you can split the wires apart by pulling them apart, but if you do that with silicone, the jacket sometimes tears. You'll need to use a very sharp knife and very CAREFULLY cut down the middle. I add a piece of heat shrink tube to also stop it from further splitting.Application: Used some 10AWG to rewire a small 10A MPPT controller, which had cheap and too small 16AWG wire. While 10AWG is slightly oversized for such a low current application, it is much more efficient.Conclusion: At current price points, rating this one 5-stars (cost per foot, higher than comparables).
