What gauge wire should I use from the panel to the charge controller to the battery to the load. All the same ??

Proper wire size is determined by the load (Amps) and length of wire needed. Search for "12v wire sizing chart" to see a breakdown. I use 16 gauge wire which will carry up to 5 Amps 15 feet with about 3% voltage drop.

14 gauge is good for up to 15 amps. I have been using outdoor extension cords that the ends are bad or has been cut or damaged, just don't use the bad section. Just keep you lengths as short as possible to avoid voltage drop.

panel to controller I use 10 gauge stranded, insulated, controller to battery I use 4 gauge insulated, stranded, battery to load depends on the load.

I used low voltage lighting wire from the panel directly to a bilge pump to run pool water to a solar heater.

I used a red and a black #18ga wire. If you want a constant read on the meter even when the vehicle is off, you will need to find a constant hot source. I ran it directly to the batt. The wire can be bought at any auto parts store.

There's an source and a load. Connect the battery to the source, connect the load (probably speed controller) to the load just as if you were connecting it to the battery. That's it. No wiring diagram needed, these things are pretty standard. Make sure you don't swap the black and red wires.

You should look at running 2 - possible 3 100 watt panels, if an upgrade for future look at 10 gauge panel wire, it seems your running 12 volt, but your inverter and charger will depend. I've got a 40 amp 12/24 charger but batteries will run at 12 bought in a kit with 6 100 watt panels but told to only run 5 as my 60 amp also takes 1600 watts if at 24, but running at 12 so 800 watts mix up and I was sent a 12 both are mppt, you can probably run 5-6 100 watts if you have 2/ 25 amps combined, if not mppt they will keep charging but at a lower rate will destroy your batteries if not in use all the time, go with 10 gauge wire you will be happier.

You would probably be okay with that gauge of wire for that short of a run. HOWEVER! Be sure to fuse the line in case it overloads or should happen to short to ground over time! I used #0 gauge wire for a 15 foot run to the back of a van and regular battery terminals to attach to the dual post battery.

Cable from panel to controller is 6' you do wire from controller to battery...

I have read somewhere you should connect the inverter to the battery. Because of the potential load you are pulling could exceed the charge controller. I am just passing on what i read just got my panels will be installing them soon

0 Gauge wire should be used!That is what is ran to my Brutus.At the very least a deep cycle battery (fast discharge) should be used!My total system wattage is 5400& I use 0 to each amplifer!The more voltage the better!!!Don't Skimp Out!

Max is 30 or 40, I just used a 25 for mine. The gauge is same thickness as a float battery charger that plugs in. Hope this helps.

it's always a good idea to use 8 gauge wire directly from the battery,fused with atleast a 20 amp fuse,otherwise a cigerett lighter hookup will work. r.cox

I would believe the instructions! Keep the + and - of the panels isolated from your trailer ground. The charge controller to batt should go directly to + and - terminals of batt ( + should go thru a 30A fuse! ).

I would use 6 gauge stranded copper wire as you don't want any more than 3% voltage drop. If operating at the high end of the 600 watt, 4 gauge would even be better. You're actually better off positioning the inverter closer to the battery source and running an extension cord from the inverter to the usage area.

I don't believe you'll have a significant reduction in current unless you start talking hundreds of feet. The specs on this say it has 3 foot cables, but on mine the cables from the panel to the controller are 10 or 15 feet long. (Maybe they changed the cables, maybe they're talking about the cables that go from controller to battery, I'm not sure). The wires are made of copper, so resistance is low. You might have to splice cables together to make the distance, but as long as you do that correctly, it should work fine. Another option would be to solder your own longer cables directly to the panel, which I think would work better.

Run the solar panel connection to the charge controller, then from the charge controller to a 12 volt battery. Works great for me running lights at a deer camp.

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

I ran 14g stranded copper wire from the appropriate (- and +) terminals on the controller to the battery. Strip the insulation from the ends of the wire so the copper makes contact with the controller. Twist the stranded copper good then insert into the contacts and tighten down.

I have the same setup with 45 watts of solar panels. I'm using 12 gauge wire, although 10 gauge will fit. No problems with 12 gauge here.
