is the m4 t branch connector used to plug into solar panel ? is wiring then attached to the connector? waht wiring would I need fo about 8 feet from panel to chalet A frame camper trailer

the purpose of this is to connect two pannels each having a pair (female and male) of M4 in to a single pair of M4 input jacks. The M4 connectors are intended to be weather resistant. To connect to the camper wiring you might try to find a M4 extention, male on one end and female on the other. Cut this in half and make the connection to your camper "charge controller" using the cut ends inside a weather resistant box or using waterproof connectors.

Yes you would plug you solar panels into these branch connectors if you plan to put two 12 Volt solar panels in parallel. If you plan only a single 12 volt solar panel, you would not need the branch connectors. Do an Amazon search for solar panel wiring and you will find cable pairs with the MC4 connectors to whatever lengths you need.

MC4 PV cable if you cut it in half it will give you a male and female end. Then you can use the cut end to wire to the controller.

I'm using the MC4 with Solar Cable size 10 awg. This insulation in the solar cable is thick so when you use it with the MC4 you will have a tight seal in order to prevent or minimize any humidity getting to the contact. Now regarding your question the insulation thickness of the solid 12 gage THHN is thinner than that of the solar cable and the MC4 connector will not provide adequate seal. The crimping for the open terminal will be acceptable. You can use it but do to the lack connector seal I would not recommended. You will have contact problems eventually. I hope this helps. Regards.

I just cut off the solar panel connector and installed bullet connectors. Just make sure you put the female side on the panel wires so there will be not accidental shorts. Has been working fine for almost 6 months now.

I can't really say. I suppose if you're getting the solar panel with controller, they assume you're going to be charging a battery on the ground, with the solar panel elevated. If you're just getting the panel, you could be doing anything with it .... and the length of wire would vary. Just a guess.

I am not sure what you are asking. As stated, the cable is 30 feet long with a male MC3 connector on one end and a female MC3 connector on the other. These MC3 connectors are used with older solar panels. All the newer panels use MC4 connectors. The specific dimensions of the MC3 connector can be found just by googling "MC3 Connector" on the internet.

The solar panels comes with 2ft. cables on both positive and negative with MC4 connectors. You don't need MC4 connectors either to open l the box. It's all plug and play.

The connectors you will need are the spade type (female) quick disconnect. The ones on the battery are the spade (male) ones.Good battery got it on a 30w solar panel running two small fans blowing the hot air out of a small metal shed.

I suggest that you use as heavy a wire as you can attach to clip or loop end to. The heavier the wire the more energy you get. Single strand or braided wire is fine as long as you can get it into the screw loop end attachment. Of course that goes onto the Charge Controller. Now it depends on what type of battery posts you have. if you have a threaded post with a wing nut or large nut then I was use another larger end loop connecter. If not just go buy some small but heavy alligator clamps, you know kind of like what the ends of jumper cables use, just smaller. I had to replace my Sunforce regulator. It failed after about 2 months of use. I don't know why but where I to guess I would say from moisture accumulating within the regulator during rainy weather. So keep it dry. I don't mean to try to change your mind about the product, because it did work well. when it worked. But when I replaced it I found a product that I like much better for a couple reasons, first and foremost it was only $35, which included shipping and it arrived in 2 days! Secondly it has a digital readout screen that tells you exactly how many volts are being produced by your panels. The Sunforce doesn't have any read out at all, only lights that I could never tell if it was working or not. I had to use my own personal digital tester to know my panel output. I replaced the Sunforce 500 watt, which was around $80 with a Thunderbolt Magnum 500 watt for $35 shipping included. Good luck with your charger and I hope I wasn't too confusing when trying to answer your question. As I stated, just use simple loop wire connector ends to attach to the charger and also a similar but larger type connector if your battery has threaded ends with wing nuts. If it has basic battery post just get some large alligator clips and attach it to the battery. Use as heavy a wire as possible, single strand is best. They work fine as long as you keep them clean. Do everything you can to water proof all you electronics.

A lot more information is going to be needed. What battery voltage are you going to be using, how far of a run, do the 100 watt panels have mc4 ends? The questions could go on for days. This has standard screw type terminals, so all you need to do is strip the copper, stick it in its hole, and tighten the screw. Hooking up panels can be a very different task if there are not mc4 ends. Then you will need a water/weatherproof junction box to combine the panel terminations, and then run a single line from where the panels. Your question is far too open ended to even try and answer. Be more specific

Approximately 18" of MC3 quick connect cables are factory attached to the panel with negative "-" & positive "+" identification on the connectors. First thing to decide is to where the panels will be installed and the location of the charge controller "Measure the distance between solar panels and the charge controller for wiring. Measure all the turns and twists the wire has to go through". I would keep all major components from the same manufacturer ie; Morningstar charge controller with Morningstar display "meter". Final component list for your questions is as follows. 2ea Solar panels. 1ea TS45 MPPT charge controller "assuming battery is 12v" 1ea PV extension cable with MC3 connectors "length according to requirement" 1ea 3 string combiner box with 2 circuit breakers "can be used as an On/Off switch as well" This would complete the RV installation.

Buy the MC-4 connectors. Then puchase some 18 to 16 gauge wire in the length you need.Attach the wires to the MC-4 connectors. The MC-4 connectors plug into the panels and the wires they are attached to go to your controller.Go to this link for more info: http://www.freesunpower.com/index.php

Rob M. is correct. It has wires and ring connectors for the battery posts but just a pair of wires to connect to your solar panels. i had extra connectors that came with my panels so i used wire nuts to splice one onto the controllers wires then plugged it in.

You can order short wires that have MC4 on one end and use these or strip the wires of the MC4 connectors. This box has only screw/clamp terminals. Normally there would be a significant distance to cover between the CC and the panels so usually have a normal run of two conductors between SP(s) and CC.

I have several solar panels. I started out with the MC4 connecters but found them both very un-reliable and hard to work with. I would lose power on a/some panels, trace the problem/s to the connectors (always). I simply replaced the line coming out of the panels with some long enough to run to weather proof plastic junction boxes, running the positive leads into one and the negative to the others. Out of those to my charge controller. Problems ended, and WAY lower cost than those MC4 connectors and the over priced branch connector un-reliable cables or over priced boxes.

Hi there. For camping. and sleeping on the back of my pickup truck. Im using a 100 watt solar pannel connected to a 125 mah battery with a 1000 watt power inverter. I also use a 200 watt heater( smallest I could find) so I wont drain the battery so quick. in other words this one can be use as well in a setu up like mine or if you want to use it in your car battery you would need to connect the 1000 watt amp DIRECTLY from the car battery. DONOT connect it of cigaret outlet. it will blow the fuse since those dont allow to go up to 1000 watts. any questions just ask :)

Hi David, the first connector (Battery) is for the battery, the second connector (Solar) is for solar panel (remember not to exceed 100 watts of generating one or the sum of your solar panels) and third (Load ) you can use for low power consumption, in my case I do not use
