25A enough for 3-4 100 watt panels? What guage solar wire? I've read 10 and 12AWG

Run solar panels to combiner box. Larger wire (#4 or 6) from combiner to charge controller and controller to bats to lessen voltage drop.

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.

I think there is a typo in the title. It's a 125 watt solar panel. I added a second panel and wired directly into my rig where my generator had been hooked up. I think the 110 you might be seeing are volts?

They say 5.6 amps. Love the panels. I purchased 6 and they work great. I would add that mine have been in the mountains and when the sun is at its peak I get about 5.3 and up per panel

I have SIX panels and I can't break 30 amps. The ratings are PERFECT, not reality. Line losses, connection losses, etc all drop the actual down. Just wire with the maximum thickness copper wiring you can.

I think you will be OK. If you do the math, 6X200 = 1200 watts. That's easily handled by wattsup. Be careful to connect the solar cells to the "source" end, also I would use a diode to prevent any chance of backflow, just as a safety feature.

it really will depend on the specs from the panels you choose but i would say if they are similar to something like the renogy 100 watt panels you could run at least four for sure and possibly more depending on the actual output from each panel. if i was running more than 400 watts of panels i would probably start looking at some of the mppt charge controllers so you can get the most out of your system.

The best way to get the proper wiring size and type is to use a wire chart. It will depend upon the current of your source as well as the length of the run. You will need to know the ratings of your solar array to get the proper size.

Hello Bart. I will recommend 24v battery bank. For simplicity of wiring, I will also recommend 12v batteries. The 4 solar panels can efficiently charge 4 120AH batteries or 2 200AH batteries. Feel free to ask more questions. rgds Emmanuel

The Renology 100 watt solar panel is a nominal 47x21.3 inches and 1.4 inch deep. The panel will stand a little higher because it is supported by an edge-surround support that allows cooling under the panel.It produces an optimum 5.3 amps. Electric calculations would predict 8.3 amps but the manufacturer has listed the 'real' output as 5.3 amps or about 64 watts.

The wattage will be OK, but you also have to make sure the total amperage is below 30A. Also, depending on how you wire those four panels, you'll get different Voltage and amperage.

In my opinion, nothing about a less than 200 watt solar panel build requires a professional. In fact, it can be quite a fun DIY project. Knowledge is really the only obstacle. Getting the best angle and position of the panel can be a bit of a challenge and you also need to watch the length and gauge of cable that you use to pass from the panel to the controller and from the controller to the batteries (lower gauges and longer cables result in voltage drop).

I used standard 14 gauge house wire from the panel to the controller and from the controller to the battery. This is ok, because there isn't alot of amps (raw power) being pushed from the panel. With 12v systems, the more raw power (amps) being used, the thicker the wire needed. You can even use regular copper twist wire, just don't go smaller then the wire the panel uses.. which I think is either 14 or 16 gauge.

Don't know why someone said only use with 2 to 3 panels at the most -- these adapters are obviously meant to connect 4 panels into a single output cable. What really counts with a solar panel is the maximum amps of current it will put out -- rating a panel in watts is just a convenient marketing term, since most people think they know what "watts" are because we've all changed a light bulb. But "watts" is simply what you get when you multiply a panel's maximum volts by its maximum amps. The seller of these adapter cables specified their amp carrying capacity in another answer and said: The adapter has four input cables and a single, thicker combined output cable with its copper conductor diameter measuring 3.42 mm (equivalent to a gauge 10 AWG), rated to carry 40 amps by the very conservative NEC - National Electrical Code, which is used for all residential building codes in the United States. Assuming the seller measured the diameter of the copper conductor correctly, then the limiting factor is the 40 amps of combined current the output cable can handle. So you could connect 4 panels to this adapter, each with a maximum output of 10 amps, and safely have a total combined current of 40 amps running through the output cable. Someday we may have consumer solar panels which output more than 10 amps, but the most you will see any panel put out right now is 3 to 8 amps. This 4-into-1 adapter cable was designed to do a specific job and seems perfectly capable of doing it. Of course, you would have to be sure that whatever cable or device you plugged the output cable into was also able to handle the maximum combined amps that your 4 connected panels would be producing.

I have had 5 amps on a really good day but of course it depends on sun light. If you hook two in parallel then you increase amps and sun light surface. I have two of the 100 watt panels on my system now and can get 8 -9 amps on a good day.

0.9 amps--that may be a bit too high for off-grid use. http://www.powerbright.com/aps1000.html

4 panels is approximately 32 apps there is a lot of variables like temperature size of your wire and proper angle to the sun under perfect condition you could see high of 36 Amps ! I would not recommend your charge controller for 4 panels . 30 amp charge controller is typically good for about 15 A continuous .

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.
