How many of these panels can the Renogy&Acirc;&reg; Tracer 4210 40 Amp MPPT Charge Controller 12/24V handle?

Power (watts) = E (voltage) x I (current in amps), so 12 volts x 40 amps =480 watts. 480 watts/250 watts/panel = 1.925 panels. With the panels only producing 250 watts in perfect conditions, and with the efficiency factor of the panels multiplied in, plus the loss on the wire between the panels and the charge controller, it looks like your charge controller should be able to handle 2 panels, barely. Only 1, barely, if you run at 24 volts.

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.

If you connect four 10 amp solar panels in parallel the resulting output would equal 40 amps +/-. Realize that the output ratings are under ideal conditions. Cloud cover, sun intensity, location of the panels are some factors in output efficiency. The output voltage can exceed 12 volts which is one reason a charge controller is needed. Make sure your charge controller is rated to handle your combined output.

I used it on 4 100 watt panels and it worked fine. I did replace it with a MPPT controller because I got up to 30% more from the MPPT controller.

I have two of them wired into the charge controller via "RENOGY® 20ft. Adaptor kit Solar Cable PV with MC4 Female and Male connectors Connecting Solar Panel to Charge controller". Works great. Make sure the controller can handle the amps.

Most larger, more powerful panels are 24-volt. A good charge controller will automatically step the 24-volt down to a 12-volt battery. I don't know off hand if the HQRP will do it -- it seems to say that it does, but you might want a more expensive controller, a MPPT controller. Also, if you have 150-watt+ solar panel, a 10-amp charge controller is too small, as you probably already know. You'll probably want a 20 or 30 amp.

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.

These are 12v panels. Unless you have a 24v mppt controller they should be parallel ( suggest to a combiner box ) feeding the charge controller which maintains the battery / bank state of charge. If these are your only two panels suggest a 20 amp (minimum) charge controller.

I actually have 4 of these 100W panels, with 3 VMAXtanks Vmaxsir 125 AGM deep cycle 12V 125ah rechargeable batteries. Today I ran 3 circuits in my house. One for the computer, the A/C motor on my central A/C, and my refrigerator. This configuration is exceeding my expectations!

I am using the panel connected directly to a large, deep-charge battery, and it works OK. You can go through a controller if you are worried about overcharging your battery.

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

It's rated at 20amp. Each of these panels are rated at 5.7amps. It should handle 2 panels, perhaps 3. I would think 4 panels would begin to limit the amperage. You can also use multiple charge controllers rather than trying to attach a larger array of panels to a single controller.

The charge control can handle up to 7A. Your 30 watt panel puts out ~1.68A at high noon. You should be fine with one charge controller charging two or more batteries and it would require more charge time. Just make sure you hook up your batteries correctly. Personally and for convenience I would much prefer to get two charge controller with two solar panels for the two batteries so that I could avoid having to move and or reconnect the batteries. A larger solar panel can would benefit you quite a bit if you need to drawn power from the battery each night. Hope you are using deep cycle batteries. The charge control can handle up to 7A.

31.666 amps is where you are with your 4 panels. I agree with AT... You need a larger charge controller or research using multiple controllers.

Renology is limited to 30 amps. If you are using an inverter -- 12 volts to 110ac -- do not connect through the charge controller. I have a 2500 watt that I have connected directly to the battery. The charge controller is only connected to my solar panels and the battery

If the panel puts out 24volts d.c. then you need a 24 volt charge controller. Many of these controllers can detect the input voltage (12 or 24 volts) and can automatically adjust to work with either.

You can reasonably connect 4 panels at 128 Watts and 24 Volts each using this spider. Connect the single lead to a 10AWG cable (sold separately from Amazon) and then to your charge controller. This is my set-up and the set-up of many other responders here. So, to answer your question, I believe the four conductors may not be 10AWG, but the single one I believe to be 10AWG. All stranded. I used the MC4 connectors sold separately from Amazon.
