Can I use two separate solar arrays next to each other on the roof connected to two of these controllers using one battery bank?

I have 2 panels, each puts out about 7 amps connected to this controller and could easily add more. Look at the specs on your panels and size your controller appropriately.

I have 40 amps of power so I have 2 controllers tied parallel to my batteries. Yes, you can use two separate solar arrays connected to two controllers. Just make sure that your solar panels stay under 30 amps per controller.

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.

No I would use both solar panels Parallel to each other and use only one controller. Make no sense to use two separate controllers. Un less the panels produce more then 30A each.

YES. WE SELL THEM FOR THAT PURPOSE, HOWEVER IF YOU ARE USING THE BATTERIES FOR ANY PURPOSE, THIS 7 WATTS WILL NOT KEEP UP. SOLAR HOWEVER IS ALWAYS A FUN EXPERIMENT. IF 7 WATTS WON'T KEEP THE BATTERIES CHARGED, ADD MORE WATTS (PANELS) (OR LARGER WATTAGE PANELS). YOU COULD CHECK OUT OUR INFORMATIVE WEB SITE AT www.sites.google.com/site/solardoityourself, or even call me directly at 305-900-09596. thank you

They have to be separate. One is to provide power and the other is for metering. Won't work right together.

You can connect at least 8 solar panels of 100watts each and I have 15 deep cycle batteries on that. You need cables mostly and maybe some safety fuses if you want.

Hi, yes you can this controller gives you the option to have multiple power heads but it is up to you how many you want to connect. Just going a little bit further from the question, the idea is to have at least 2 without you having to turn them on and off.

Yes, just connect it independently to the batteries(not through the solar charge controller).

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

Yes this will work. The whole purpose of having this controller is so that once a battery is "fully charged" (at ~14V), this will "disconnect" or "shut-off" the charging so you don't get the battery up to levels like the 17.5V you mention (where it will damage the battery). Even if the solar power is at levels like ~30V (while it's not charging the battery), this will still function blocking the solar power from getting to the battery until the battery voltage comes back down to 13V where it again lets the "charge" power thru.

I have had four one hundred watt panels hooked up to this same charge controller for nearly a year and it works fine. At first, I had them hooked up with the panels at 12v and the battery bank at 12v, then I switched the hookup to two sets of two panels in series to put the panels at 24v with the battery bank remaining at 12v. I get a little more power out of the panels this way because a lower amperage means a smaller voltage drop between the panels and charge controller, even though the wattage from the panels is the same. It works fine. With an MPPT controller, the voltage of the panels is not dumped directly into the batteries so you can hook it up either way. If you hook the panels in sets to reach 24v, then your only limit is the 30 amps to the battery bank. Anything above that is simply lost.

Depends if you connect the controller to the panel then you could connect it to each battery but not both at the same time.

Yes, but would have to ask, why 2 charge controllers to 1 battery or battery bank ?
1051501
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 however you will need a controller capable of handling both panels. Most small inexpensive charge controllers handle 7 amps or less. Two 60 watt panels will produce more than 7 amps on a sunny day.

No.The circuitry is designed to look at the battery conditions (voltage, current draw etc.) and another charger in parallel would confuse that.If you need more power, you need to buy a larger charger or get multiple solar panels and feed those into Delran's separate solar controller.

Based on my experience with this, you will need two of them. Also note that they must have very direct sunlight, they don't work well on cloudy days either. All the controllers I am familiar with have the diodes built into them, or at least I thought they did. Mine is working just with the controller.

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 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.
