Would this controller work with one Grape Solar 280-Watt (36.4 volts) Polcrystalline Solar Panel for 12v battery charging?

The Tracer2210 is rated at only 260W @12V and your panel at 280W. That means you would be overstressing the Tracer by 20W. I would not want to run that risk. It might work though.

I am currently using Grape Solar panels. I have been online over a year with now problems at all

Yes, it will except 30 volts. The open circuit voltage of your panel will exceed 30 without load and cause a fault. A 12 volt battery will have to used since this controller is designed for lighting after dark. Mike D

Absolutely. Just make sure the solar charge controller is 12VDC and rated appropriately for the output of the solar panels.

Assuming both batteries you're hooking up in series are 6 volt and of equal capacity and condition then yes, they should charge just fine with a single 12V controller. However, keep in mind that mismatching the two batteries in respect to capacity or condition can dramatically limit the overall charging capacity and run time of the entire string.

I believe in a crude way it will work because the battery should clamp automatically the voltage down. However, this can only be a temporary solution. The charge controller is indeed the way to go. Try midnight solar

I use my charge controller with a 12 volt converter, but I think you can put as much power in as you want,and that it will charge a 24 volt battery bank.Since I have 12 volt converter, I had to put all my 12 volt batteries in parallel, so as not to go above 12 volts and exceed the converters volts

Yes this is great for 12v but should us the SS-MPPT-15 charge controller with it. Thanks, ML SOLAR

This controller will handle up to 30amps. So for example, I have 3 panels at ~145w each (~7.5 amps) that are connected to each other and run to this controller. Since I'm only bringing in max around 22 amps, then this one controller is plenty. I could actually add one more panel to it of the same size as my current and it should continue to work fine. To answer your question though, yes, if your panels are large enough to put you over 30a with two panels, then run them side by side and connect the two controllers to the same battery bank without issue.

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 it will work. I'm using two 100 watt panels wired in series to get 24 volts running to the charge controller and then to my 12 volt battery bank. works great. You'll have have less resistance from the panel to the controller in 24 volts as well.

I think you need to check your controller specs, but I know some controllers may just shut off to prevent damage. Also note these panels are higher voltage which may not be compatible with your controller. I bought a charge controller that won't work with these because the voltage may go up to 45V on these panels. Now I run two of these with the Morningstar MPPT 45A charge controller. Morningstar has a calculator on their site that will confirm whether a planned setup will work with their charge controllers or not. I am planning on adding one more panel to my setup. The 45A MPPT charge controller can handle 3 of these panels. Good luck!

yes the voltage output will vary with the amount of sunlight. I have my panels setup to produce a max of 36 vdc charging a 12 vdc battery bank. your charge controller needs to match your projected final system capacity, if there is a possibility of adding on later. I have a mix of 144s and 88s

I don't think you can connect 1 solar panel to multiple controllers effectively at the same time. I would rotate the batteries as needed for charging; only one controller would be needed.

You don't give enough information to answer your question. You need to know the voltage and the distance. If you download the catalog from Backwoods Solar.com. It's free, it has a wire chart on page 51 so you can figure out the right wire for your site. This catalog has a lot of good information. You should have it. That's a lot of wattage for that controller. You might double check that. Dan

You won't want to connect the panel directly to a battery, as it could damage or overcharge it. The panel itself only provides a voltage, you need a charge controller between the panel and the battery. The one I used (http://www.amazon.com/gp/product/B001HWQZNQ/ref=wms_ohs_product?ie=UTF8&psc=1) is not currently available, but should give you an idea of what to look for. You want a controller that can handle at least 30 watts and 17.5 volts input for charging 12v batteries.

Yes BUT... You have to buy a charge controller that can "step down" the 36 volts from the panel to 12 volts for the batteries.Look at Morningstar controllers and or go to Morningstar's website to get the specs on an appropriate controller for your application.

Should work it is pushing the controller hard but I am doing (1) 255 watt panel with a 12 volt system and works fine good luck.Lon
