Can two 5w panels be connected to the controller and then the 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.

Yes, as long as you do not exceed the voltage and current limits of the controller. For instance, if you are connecting two 5 watt panels in series, the voltage will be double that of a single panel but the current would be the same as a single panel. Conversely, if you're connecting the panels in parallel, you'll have double the current but the same voltage. In that case you'd want to ensure the controller is rated for the increased current.

Yes- I have connected a 240w panel (30V @ 8amps) and also two 135w panels (total 35V @ 3.8amps each) and it works fine. The limiting factor that may cause the confusion is that the maximum output is 240watts (12V @ 20amps) if you are connected to 12V batteries. In my case, I was connected to a 24V battery bank and was dumping about 17amps at 26volts into the batteries when I had all panels connected (the 240W + 2x130w). For the money the controller works well. If you connect to 12V battery; 240w is maximum; if you connect to 24v battery you can get 480w. It doesn't support over 32 volts, so you can't use a 48V battery bank.

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.

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

Nothing special. Connect the panels in series, run the wires to the controller. The controller has screw down lugs - insert stripped (tinned optional) wire , and tighten down the screws. Same kind of connections on the battery side.

The quick answer is yes! However, chaining them would technically double the voltage while keeping the current (amperage) output the same. As there is only a single connector on each panel, you can only combine their outputs using a Y-adapter similar to what you have suggested. I have done this with other solar panels of this type. While the output voltage would remain the same, it should double the amount of current. I would suggest the use of a charge controller on each panel ahead of the Y-adapter to prevent backfeed and maintain a steady supply of 12V power to the device requiring power.

A controller is required for these panels as they pruduce 4.2 amps at peek output

One connector goes to the solar panel, one to a battery and the other is for direct connector to another device. So unless you had a splitter from the dedicated battery lead, only one battery can be connected.

You can connect at least 8 solar panels of 100watts each and I have 15 deep cycle batteries on that. You need cables mostly and maybe some safety fuses if you want.

Hello, yes! You sure do! Saitek Also sells an extra power ac, I'm using it and works perfect. I have 5 panels connected

i used 12 gauge from the solar panels to the controller and from the controller to the batteries i used no 6 awg i already had here The no 6 is probably overkill i wouldnt go any less than 8 from the controller to the batteries what is your battery bank at least 24v i hope

Hi, For this panel a 10 Amp Controller will work and be expandable up to 100W at 12V. Thanks, Renogy TO

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.

Dear David. I have not done so, however the literature that came with mine indicates that you can "link up to 10 panels together for more power." There are however no instructions provided for doing so. My one phone call to Sun Force about a different matter was very responsibly answered, so you might call them. I see there is another response to the contrary by 'Daddio'. In passing, I use the panel and the charge controller that comes with it to maintain the charge in a 12-volt heavy duty auto battery that provides LED emergency lighting for my home. I've been very pleased with it. It would seem to me unless there are other considerations that it would be more economical, and present an easier mounting problem to purchase a larger (more power (wattage)) solar panel to begin with. Hope some of this helps. Randall

Yes, but would have to ask, why 2 charge controllers to 1 battery or battery bank ?

I have not tried this and wonder why you want to unless you have too much power for one. They do make a controllers that works up to sixty amps. I don't know how you want to wire this. Using separate panels is the only thing I can guess. I use my meter every day to read the total amps going to my batteries and the voltage at any given time. The lights on the front of the controller tell you most things about the system but not the voltage or the current. The voltage tells you how close you are to a full charge. If you have two sets of panels you would need two controllers with two meters. Hope this helps. I have not tried this and wonder why you want to unless you have too much power for one.

Yes, the 30A controller can accommodate up to four (4) 100W panels @12VDC and up to eight (8) @24VDC
