How many of these can I connect in parallel to my battery bank?

I presently use three in parallel. When I was able to talk to a tech. At Renology he told me I could use several in parallel and the units would automatically self regulate. What is several? Who knows. I just know that three will work.

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.

I don`t know what the limit is but I have five in parallel.Each one is fed by two panels hooked in series rated at 280 watts each.Thats a total of 10 panels feeding 30 deep cycle marine batterys.All of which qualify for a 30% rebate off my federal incom taxes.Never. Never,Never apply solar panel power to these Tracer units befor you hook up your battery power to the controllers.I found out the hard and expensive way that the controller needs the battery power to regulate the current coming from the solar panels.No regulation equals high current from the solar panels and a burned out control unit..Good luck.

I'm a little unsure of your question but by "these" if you mean controllers, I would assume you have solar panels exceeding the 40 amp capacity of a single controller. I think you could connect any number of them you wanted to in parallel each controlling its own set of solar panels. At some point I suppose you could reach the limit of your battery bank's ability to accept any more current though.

You can hook up as many batteries to it as you want man just make sure its 12 volt series. Like I have 4 batteries I took off of oil pumps and I connected them in a parallell series. Like I went to auto zone to get the wires to hook it up from one battery to another and then from the battery to the power inverter but I only used one positive and one negative bolted on to the inverter I didnt use all 4 and let me tell ya haha this thing powers my while cabin like a champ! I think I might have misunderstood your question but ive got mine all hooked up and stuff so I can help. carson.ross83@gmail.com You can hook up as many batteries to it as you want man just make sure its 12 volt series.

I don't know I don't have a third battery you can not charge just one battery you have to have both batteries hooked up to each battery connector

You can have this connected to as big a battery (or bank of batteries) as you wish, just keep in mind that this can only handle the 7 amps going thru it (for charging or going to the "load" connection, but there's only one "battery" connection point).

Can't say for sure but battery packs usually are not meant to simultaneously charge/power multiple gadgets.

What four wires? I have a six battery bank connected in paralel (positive with positive, negative with negative) and in the same way to thepower inverter. do the same with the charge controller in the other extrem of the battery bank

I have two of these, and hook them together all the time. You can hook as many as you want, as they have an output jack, and each one has its own power supply.

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

Connect the positive cable to one end of the battery bank and the negative cable to the other end of the battery bank if possible.It would help distribute the load evenly.

Ah! So you are saying that if charging 1,2, 3 or 4 batteries, it is best to place one in each channel - NO in pairs. Thank you for the clarification.

You can plug a separate balance board directly into the unit for each battery. If that helps any.

I can't speak to 5 batteries, but I have 4 yellow tops connected together in my solar array and hook this charger onto the side posts of the last battery and the charger maintains all 4 without a problem. It may make a difference - series v. parallel - I have mine connected in parallel.

I've hooked up several on a battery that I keep charged with a solar panel. If you are using a power supply just be sure to over size it.

I also would not recommend doing that. On a 2 bank charger there are 4 connections 2 pos. and 2 neg. connecting all 4 to 1 battery would not be possible. If your device calls for 1 battery purchase a 1 bank charger.

Yes, you can make into a parallel wiring without any problems. This will increase overall battery capacity (50 + 35 = 85 ah) If that is what you are looking for.

yes that is correct. If you connect two 12v batteries in series end result will be one battery bank of 24v. When charging batteries - use of a charge controller is highly recommended.

Yes you can hook them up together in parallel and the voltage will remain the same but the amperage will be 4 times that of one panel. You will definitely need a charge controller with what is going to amount to 80 watts of panel input to the battery. It might be helpful to know more specifics about what you plan to do. If you want to just keep a battery up this is far more panel than you need. If you plan to use the battery daily to power things than 80 watts may or may not be sufficient depending on the size of the battery, the wattage/amperage draw of the loads, and how much daily sun you anticipate. There are a lot of variables. You will also definitely need fuses for fire safety. Hope this helps. BTW, it might be cheaper to buy a singe 80 watt panel as opposed to four 20 watt panels.
