BougeRV 44PCS Solar Connector with Spanners IP67 Waterproof Solar Panel Cable Connectors Male/Female 22Pairs(10AWG)

Build you own cables. Repair solar panel wires. Very handy. Easy to use. Get the crimpers and you're all set. Comes with the tool (blue thing) to disconnect to two parts. They feel solid. I've made several extension cords for my panels that I lay in the driveway during power outages...run into the garage where MPPT controller and batteries are. I bought used panels without ends super cheap and put these on in a flash. Building you own solar array and don't want long cables dangling around--cut them down and put these on (remember all cables have to be the same length).

They fit the solar panels I purchased and installed easily. Don't forget to slide the caps on before crimping the connector!

Don't mix-n-match connectors and don't strip too much insulation when making crimp connections to the male or female metal connectors. After two years of operating my ground mount (26ea 410watt panels) running 3 strings (2ea 10panel strings and 1ea 6 panel string) I have experienced 3 times a wire meltdown, always at the mc4 connector. My strings are 170 feet 10ga wire into 2ea EG4 6000xp's. I love it, I love it, I love it. Total off grid configuration with grid as bypass when batteries low or >12000watts required by home. 10panel series strings = 300-380volts, 6 panel series string = 180-225volts, temp dependent. Very important, use same connectors everywhere on your system. Cut the connector off your panel and use all same. I like the BougeRV mc4 connectors, they work well. My problem was improper wire connection to male and female metal pins. Strip about 1/4" insulation from PV wire, DO NOT break any of the copper strands, not even one when stripping the PV wire. DO NOT strip too much insulation when making crimp connection. Bare copper wire should just barely protrude from the crimp clamps about 1/16". Use proper crimp tool. My mistake was running the bare copper wire up into to hollow part of the metal pin, fine if filled with solder, but unnecessary. Any loose strands will arc creating heat, wire failure and/or fire. This includes that broken strand you may have created when stripping the PV wire insulation. That broken wire will arc to the metal pin creating heat. Use a proper wire stripper and use ferrules on all PV combiner box connections, isolators and inverter connections. Try to run system in series as much as your inverters will allow. The higher the voltage the better. Good luck and be safe!

Some sources say that these connectors can have different measurements depending on who manufactures them. So in order to prevent possible poor connections I only use these BougeRV connectors. I like the fact that BougeRV is a reputable company and that these connectors are readily available in these large packs at Amazon.

Pay for a brand - These are good. These connectors were purchased to replace very poor quality ones from a different supplier - which I immediately returned. These connect and release cleanly as they should, and work fine.

These arrived in a timely fashion, and appeared to be good quality at a fair price compared to other ones that I have hooked up.

As long as you have wire strippers and special crimping tool they work great to make new cables or replace old connections

These so far as the best I have found on Amazon. Why? They come in nice packaging and seperated into connectors vs the internal cable ends. This company provides/gives you extra metal connectors as they suspect mistakes or bad crimps happen. This is awesome because nothing is more frustrating to have a crimp getting ruined and you have more plastic than metal. The size and fit are perfect and much less connection problems compared to other non name brands in this same price range. This is the first time I haven't experienced woes with connectors. All of the connectors and metal pieces are uniform, can tell have been through some qc and just work. Others I have experience about 20% dead loss due to bad QC. I've almost used this whole pack making cables and I will be ordering more.
