Can I use 2 of these controllers on 1 battery bank?

I don't know why not, then again I am not an expert, just a home user.... I would hook them up to different battery posts though...

I am not an expert here but I would not do that. What I would do is have two different battery banks with a photo sensitive switch that connects the two banks at night. That means, during the day, the banks would be separate but when the sun goes down, the switch would turn on and connect the two battery banks. I have never heard of anyone doing my idea but I think it would work. You are getting advice from an non-pro here so do not act on anything I say without talking to a pro first.

I'm sure you can. Weird that the other charger was unable to charge the controller.

If it works fine with one than probably no concerns. I have noticed I can run it with one as well and odds are using two is mostly for extra power.

Yes, but the answer is not as simple as connecting the batteries in parallel. Because each battery has slightly different capacity and internal resistance, over time, you will get uneven charges between them. The charge controller will stop charging once one of the batteries gets full, leaving the other not-fully changed. The result is reduced capacity, that is, you will not get twice the capacity of individual battery. The solution is to insert battery balancer between controller and batteries. See this wiki page. http://en.wikipedia.org/wiki/Battery_balancing

Yes. You can control 2 devices independently with 5v digital high, low state. I like this better than 12v since arduino type controller already has 5v power availibility.

You will only need one battery tender unit if you use a splitter to both battery banks. Home Depot or Lowe's would be a good place to get what you need, and be able to talk to someone face to face.

The short answer is no, however with additional controllers, inverters, breakers and fuses any power sources can be combined. Wind, Solar, Hydro electric, even thermal. When combining these power sources to charge batteries it is best to have the experts design a system that will work for your specific application. This will save you money in the end.

Only one battery is needed for each wiimote control. So, two batteries = two controllers.

It will handle two batteries okay. whether it will charge both or only the one it is connected to depends entirely on how you batteries and electrical system are wired.

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.

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

It's not recommended as the charge and discharge rates are different for the two batteries. It's best to use two batteries of the same capacity.

If you are going to connect the 2 sets the all you need is 1 controller. If you are going to use them in separate situations you will need two controllers.

Yes you can. Just be sure to sync one before you turn the other one on. Hope this helps.

This can control two 12v items but not individually. both items will be powered at the same time.

You could have them both connected to the same battery. Each has its own controller.I do not know if you can wire them for any configuration other than 12v....

No, it only allows one of each. However, there is an extra usb connection that allows a cable to be used for charging another motion controller
