If I configure panels in series (24V) can I have my battery bank still be 12V?

Yes, The MPPT charge controller does the input/output conversion internally to provide the most efficient charge voltage and current. Mppt controllers are about 30% more efficient than the old type.

I believe you can, but that doesn't mean that you should. Making the controller to all this conversion will severely alter its efficiency. There are charts in the manual showing just how much you lose, the more converting you force it to do. You're best off trying to get your panels bank output configured to be as close to battery voltage as possible.

Yes you can, if you put it on series you have 24v output and the same amps, and if you put it on parallel you got 12v output but the double of the amps

If your solar setup is designed to charge lead acid battery's wired in series for 24V, then yes. You will need to adapt your charging setup to use the same type of adapter that plugs into the side of the pack.

The capacity is 400W at 12V and 800W at 24V, so you can use one panel at 12V and up to three on 24V.Thank you for your interest.GordonGLR Industries, LLC

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.

Yes- I have connected a 240w panel (30V @ 8amps) and also two 135w panels (total 35V @ 3.8amps each) and it works fine. The limiting factor that may cause the confusion is that the maximum output is 240watts (12V @ 20amps) if you are connected to 12V batteries. In my case, I was connected to a 24V battery bank and was dumping about 17amps at 26volts into the batteries when I had all panels connected (the 240W + 2x130w). For the money the controller works well. If you connect to 12V battery; 240w is maximum; if you connect to 24v battery you can get 480w. It doesn't support over 32 volts, so you can't use a 48V battery bank. Yes- I have connected a 240w panel (30V @ 8amps) and also two 135w panels (total 35V @ 3.8amps each) and it works fine.

Val this charge controller can only handle a maximum of 500w of solar for a 12v battery system, or up to 1000w for a 24v battery system. Since you are planning to use 3 x 250w, you will need to wire those batteries in series for 24v, and get a 24v inverter. If you don't want to go for a 24v battery configuration, and want to stick with 12v, then you will need to drop a panel and just go with 500w, or you will need to use an additional controller (controller 1: 2x250w, controller 2: 1x250w or 2x250w).

you can connect them series and parallel to get output voltage of 48V. If you get a shadow on one of the panels, it will greatly decrease output. You also need to be careful of the guage and length between the CC and panels and the CC and the batteries. Voltage drop in low voltage DC is important. A wonderful resource is handybobsolar.wordpress.com.

You need to keep your voltage all the same, you can use this controller with a 24 volt panel but you need to have your batteries wired at 24 volts and if your using an inverter it needs to support 24 volts.

I had to hook up 2 12v battery to make it a 24v bank and plus a solar charge controller between the panel and the battery bank to prevent over charging

A test you can make is to directly connect the panel to the battery, correct polarity important or you will fry things. If the voltage is 17 volts or under you are good to go. If it is still over 18 volts you will be over current and ruin the battery. You cannot have the controller set to 24 volts for your 12volt battery!

if you have 12v batteries in series your adding to the voltage therefore your batteries together are 24v not 12 anymore. if they are in parallel then you will still have 12v just double your amp hours. this charger says its for 12v only i wouldn't recommend it.

The panel puts out 12V DC, so charging the 12V starting battery is no problem. I wouldn't charge a 24V system with a 12V panel, but if you disconnect each of the 2 12V batteries for the trolling motor and charge them separately, that would work.

You need to connect the panel with solar wire connectors like the MC4. You can connect to several batteries as long as they are connected with the correct voltage ie 12 or 24 volts depending on which way you go with the charge controller. Connecting 12v batteries in parallel will give you 12v. Go in series and you get 24v.

I'm pretty sure the answer is no, at least not without finding a way to cut the Bbank output from 24 down to 12. I have one of these 800s I keep in the car and the input terminals plainly say "DC/12V." I also have a Whistler 2000W connected to a 12V battery bank and it says the same thing.

Yes it will I would wire your panels in series for 24 volts to the controller for best results and you bankroll have a 12v battery bank

You would be looking at around 37V to charge a 24V battery bank at minimum. You can get 3 of these 37V panels and wire these in series and pump 111V under load into the battery bank with this controller. As long as the Voc voltage doesnt exceed 150V. The Voc voltage for these 37V panels is around 45V. You will get the 37V once its connected to the controller and in use but the panels will 45V just sitting there and measured with a voltmeter.
