What type and how many connectors do I need to connect 2 of these panels to a 30 amp charge controller? Thanks!

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.

Dear customer, you will need a branch connector if you want connect two panels in parallel.You can find the product here:http://www.amazon.com/Branch-Connectors-Connector-Solar-Panel/dp/B00BCWRB48/ref=sr_1_2?ie=UTF8&qid;=1376241228&sr;=8-2&k;eywords=MC4+Branch+connectorYou will also a Adaptor cable from the MC4 branch connector/MC4 connector to the charge controller. The length is to be decided by you. Thanks.

There are Mc-4 male and female, the controller usually is abayonette type but it could be just a internal clamp with screw to connect a stripped cable.

I could not find cable for sale that would connect the two. i purchased an extension cable for the solar panel, cut one end off and attached it to the controller.

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

You will need a charge controller and wiring to connect the solar panel to the charge controller and the cable from charge controller to the battery.

My panel is 50W, and this controller could handle more. It would make sense to me to wire them in parallel to keep the voltage around 12-14V and double the wattage.

It's made for a 24 volt charge controller. If you just have a 12 volt controller get 2 100 watt panels from home depot and wire them in parallel.

This panel comes with MC4 connectors on the end. To use those connectors, you'll need these:HQRP Pair MC4 Solar Panel Connector male & female (M&F) for PV / Photovoltaic System plus HQRP CoasterHowever, you could also just cut off the factory connections and wire it with whatever other connectors you want. The MC4 connectors are nice, but are also very expensive.

If you plan to add more panels, you will need to use a bigger charge controller or stack another charge contorller. This charge controller only only fit 240W and 480W for 12volts and 24volts system.

Hello I hope which I hope you you need 10gauge wire you need a shunt a amp meter for you know how many amps you are receiving from your solar panel it could be 100w or 50w.the wires coming out of the path into the charge controller must be 12 V have the battery don't forget your user have relayed or fuses him all the connections and you should be good if you could go to youtube on your computer and you will learn everything you need to know I hope this helps you and thank you for asking my pleasure to help you

You need to connect the panel with solar wire connectors like the MC4. You can connect to several batteries as long as they are connected with the correct voltage ie 12 or 24 volts depending on which way you go with the charge controller. Connecting 12v batteries in parallel will give you 12v. Go in series and you get 24v.

These are peel and stick panels so your won't need a rack. You will need to look for "mc4" solar cable (25' run-get one 50' cable (cut it in half) with one male and one female connector and a charge controller of it's for 1 panel. Its recommended to get a combiner box and higher rated charge controller for more panels. Hope that helps.

I bought two panels, have not installed them yet. Starting out with 4 batteries @ 100 amps, plan on going to 8 and adding two more panels

Correct. You do not need a seperate charge controller unless you are putting more than 15watts to the battery. That's three panels! It says the same thing in the owners manual.Correction: I see this is for the 7watt panel. In this case that would be TWO panels total. I have the 5watt panels, so that is where the math came from. The 15watt limit before needing the charge controller still applies for all panels.

If you are just going to charge batteries then all you need to provide is the wiring and fusing from the charge controller to the batteries. You also need to find a good way to mount the panels. They are 2'x4' each.

You need a charge controller. I bought this one AGPtek® 30A Solar Panel Power Battery Charge Controller / Regulator 12V / 24V 30 Amp with PWM Type of Charging (Automatic Lighting Control + Time Functions) , but I had to cut the wires on the solar panel to connect to the charge controller. You can get adapters, but I'm not sure what those are called.

No they will not. You will need to make a set of pigtails using a set of quick connects with bare wire ends. this will let you use the ones from your panel. Be sure to solder the ends of the bare wires before putting them into the screw downs at the bottom of the controller to give you a good connection.

I would not design a system with parallel battery charge controllers. I would combine the panels (or strings) using a combiner box and then wire it to a single battery charge controller. If the 40 MPPT is not big enough, go to a larger charge controllers, they come in all sizes. Very large systems may need multiple charge controllers, but then they have to be sophisticated enough to not fight each other. The Tracer is a good controller, but not a sophisticated charge controller.
