These are parallel connectors. Two males connect to the two females, and resulting in one male. Since male from the panel is normally positive, the single output is still positive. They shouldn't have marked the two inputs on the connector.

Depending on how many panels your connecting there are options 12 or 24 volt this is a link to the Renogy downloads with several schematics for different configurations. This link goes to the 2 panel setup using connectors http://renogy.com/wp-content/uploads/2013/12/200W-1x2.pdf. The next link takes you to the downloads page where you will find the configurations. http://renogy.com/renogy-solar/products/downloads/Hope it helps.

Sounds like they are mismarked. The polarity cannot change through the connector. The two + now become 1 +. The two - now become one -. Once you have the 2 panels connected in parallel, use a voltmeter to check the polarities to prove it to yourself.

No polarity does not change, With out seing it my guess would be the plus and negative signs are taking the place of male and female. In other words if you were using a single connector you would insert the male part into the female part of the connector. I have many panels hooked together with these connectors and it doesn't change polarity. I would recommend phasing plus wires from panels with red phase tape and phase wires back to invertor or charge control, makes it a whole lot easier to keep track of what is what.

They have a common negative or ground. The positive side is switched through the regulator

It's right there in the description for the product: one port 1A maximum and the other port 2.4A maximum with blue LED indicator. So it means you've plugged a cable into the port with the 2.4A maximum. They're labeled right above each port which is which.

I used the one labeled "pwr in" AND has the Positive (+) and Negative (-) symbols

This is a switch so you only want positive connections - one from the battery and the other from the load. These generally attach to the largest of the 2 studs and it normally doesn't matter which one the battery cable attaches to and which one the load cable attaches to. The 3rd terminal is for the Switch and often this terminal has an S next to it but not always. You shouldn't have to do anything with your negative cable(s) which should already be connected properly. If this is a brand new circuit then connect the negative cable from the load(motor,etc)to a negative bus bar or the negative terminal of the battery This is a switch so you only want positive connections - one from the battery and the other from the load.

Sorry, but then I don't know the answer to your question. Quite frankly, my understanding of the A & B notation is simply the twisted pair order not the diameter of the cable. I've been doing this for years and this is the first I've ever heard of it. Good luck.

Usually you use the two outside terminals or whichever ones are marked + and -.Polarity does not seem to matter to the charger.

Hi Shard, my initial assumption is that you do not have the connectors in the right place. The batteries are connected in series i.e. mine are 6volt batteries and I have 6 of them for a total of 36v. So the positive connectorhas to be on the 1st batteries positive terminal and the negative connector has to be on the negative terminal of the last battery. If you have it hooked up that way, one of the batteries might be bad. Bill

All points on a bus bar are electrically from a single point. So if you wire one point to the negative terminal, then all posts are negative. If you wire one post to Positive, then all posts are positive. You would never wire both the positive and negative together on the same bus bar or you will have a firery short circuit.

You could technically make either positive or negative. Just dont mix them up. If youre asking a question like this you might want to have your home theater system professionally installed. Personally I use the white line as the power positive red....black is clear ground.Good luck

Yes polarity matters. I don't know which is + or - however. I tested it one way, didn't work, reversed the polarity, worked.

it makes no difference which terminal side is + as long as you put the + on the SAME side as all the other speakers. if you get one different, you will notice a marked loss of bass. typically, the + wire is a solid colour, and the - has a stripe on it. so if you put the + on the left terminal on ALL speakers, your good to go.

simple speaker wire positive and negative. On my system I have a dedicated subwoofer positive and negative terminal.

Each end of the connector cable has a different type of connection. You just have to make sure you match up the correct end to the correct input. They do a good job labeling it in the instructions.

See Karlberg's comment. Also, both studs are for Positive inputs. There are no Negative (ground) terminals.

Yes A negative sign (-) will display on the meter when checking DC voltage and the meter leads are incorrectly placed on the voltage source. When the meter leads are reversed, then the negative sign will not appear.

mine has yellow and black, the yellow is positive and the black is negative, I will guess the brown is negative and the yellow is positive, a continuity tester will tell for sure
