Will the RenogyÂ® Tracer 4210 40 Amp MPPT work with these panels and how many at 24v. each.

Hello,If you are charging 24v the controller can support 3 of these panels.In 24v the controller can support up to 800 watts.Please let us know if you have any further questions.Regards,Austin WaltiRenogy Technical Support Rep.

The panel is rated for a nominal rating of 24V. It can deliver to a 12V or 24V battery bank based on the charge controller that is used. If you are using a 12V battery bank you will want to use a MPPT controller.

Frank, i have a Renogy catalog on front of me and don't see a 350 panel. This must be something new. And by 30ampcharge controller I assume a PWM charge controller. Your panel can be 12 or 24v not both, unless this is somethingreally new. You might try one of the solar forums or email Renogy support. Don't call tech support because i tried.Don't. Ok? Try Northern Arizona wind&sun; or midnite solar forums. Also midnite solar has videos on youtube about everything. You should be able to charge a 12v battery with a 12v panel and charge controller-period. Unless the battery is no good. Put a voltmeter at the output of panel then the output of charge controller. Good luck. Frank, i have a Renogy catalog on front of me and don't see a 350 panel. This must be something new. And by 30ampcharge controller I assume a PWM charge controller.

I can confirm Renogy Solars answer (it'll work with either 12V or 24V battery banks). I use this panel with a MPPT controller and a 12V battery bank.

I think a 20A would be the min I would hook up two panels to. I have 4 panels wired in series and parrallel to a 40A MPPT controller. The MPPT vs PWM is a different thing completely. You can google the difference between the two. I have had great luck and success with MPPT TRACER 3215RN Solar Charge Controller 30A 12V 24V EP I've used this one and the same brand in 20A. These are great panels and make power even in moonlight.

Contact manufacture of your panels on what the output of both panels would be relative to your Volt/Amp requirements. It has been many years since I used Ohm's law! Good luck! (my connectors are still in the bag, as I had the same question,I received no response when I made my inquiry)

Because the voltage is 40 volts, you need to buy a voltage controller that accepts input for 24 volt or 12 volt. and the output for the battery will be 24 or 12 volt. The voltage controller will automatically detect the input voltage of the solar panel and will automatically detect the battery voltage. I have purchased two of these items on amazon. However, One seller was in Shanghai and the other in Hong Kong. you can get 30 watt or 60 watt. Blue Solar was the name of one of them. I did get both delivered after a while.

If you are using 4 panels with this kit it only uses a 20 amp controller. You must be using a 24v battery bank to use up to 400 watts. Can you explain your situation a little more? We are a bit confused with what setup you have. Thank you. AW

Those two panels if in either series or parallel will still be over the max rating for the Midnite Kid 30 Amp controller. You can test this by using their Midnite Solar Kid Sizing Tool. However, the system will work if you switched your battery bank to 24v.Thank you,AW

I would not design a system with parallel battery charge controllers. I would combine the panels (or strings) using a combiner box and then wire it to a single battery charge controller. If the 40 MPPT is not big enough, go to a larger charge controllers, they come in all sizes. Very large systems may need multiple charge controllers, but then they have to be sophisticated enough to not fight each other. The Tracer is a good controller, but not a sophisticated charge controller.

The goal of using an "MPPT" (maximum power point tracking) controller with a panel like this is to automatically detect how much power you can get (in both volts and amps) from the panel, then take that and put out as much power as you can to the battery you're charging. On many panels like this, the actual optimum output (to get the "50 watts" it's labeled as) is at something like 19V & 2.6 amps, yet charging a typical 12V battery (which is "fully charged" at 14-14.5V) would mean that just connecting it directly only gives you ~40 watts with the 2.6 amps at ~14V. An MPPT controller will take in that 19V 2.6 amps and give off ~14V 3.3 amps where both of those powers are ~50 watts, but are obviously different V & A ammounts. So being able to take in all the power you can (but not be virtually "shorting" out the panel) as well as "transform" all of that to the best voltage & amps takes a lot more circuitry than a cheapy controller that just "switches on & off" based on reaching the battery "full voltage" level (or detecting a drop in battery voltage). You can choose to design a controller intended to be able to handle 100 watts, 500 watts, 1000 watts, or any other range you want (which can be for certain size panels and/or battery sizes). One MPPT controller I have even says it can take in power at 19V, 38V or 69V from panels and then put out power to a battery bank at ~12V or 24V systems (and will automatically detect the power from each of those systems & adjust things internally having the same "input" and "output" connections for any system). Of course you still need higher input voltage than output, so you can't charge 24V batteries with only 19V input (unless you can come up with a way to "transform" things in that manor). Hope you can come up with a fairly efficient circuit design.

Hello,For x4 of the 250 watt panels would be too much power for the controller to support in 12v let alone in 24vThe minimum you should go to run these on 12v would be roughly 96 amp controller such as the MidNite Classic.Please let us know if you have any other questions.Regards,Austin WaltiRenogy Technical Support Rep.

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.

Yes it will work. The "20 Amp" rating refers to the amperage produced by the solar panels, so if the current produced by your panels at peak efficiency is below 20 amps (and off the top of my head, it is) you will be fine. Remember to hook this up in the EXACT order as the instructions say or else it ill blow a fuse. Good luck!

I probably will not be much help here, yes they should be the same. 24 Volts in, 24 volts out. My Xantrex did not hold up however, and caught fire within 1 month. I now have a MidNite Solar Classic MPPT Charge Controller - 150V, and it is performing great.

Your panels are rated between 5 and 6 AMPS at 18-20V. The Charger is designed to handle 20 AMPS up to 32V. It is also used as a timer to support automatically running an electrical output circuit.3 panels are within guidlines. Your maximum PV INput would be about 460W at 22V. You could add a 4th panel without losing much efficiency.
