If the solar panels are wired for 24v input to the controller, can the controller be set to output only 12v to the batteries?

The whole point of this type of controller is to take your solar power of any voltage up to 48 volts (in this case) and output the proper voltage 12 or 24 volts to your batteries. Your panels do not need to be 12 volts, they simply need to fit in the specs of the controller which is a 48volt maximum input voltage. It will then regulate your output voltage to 12 or 24 volts, whichever you choose.

No it will not do that....if you have two 12v panels wired in series to produce 24v you could change to parallel to get 12v.....

only if you use a 12v charge controller and have you batteries wired in series. the output of the panel under load is a bit over 24v.

The PS-30M controller automatically selects 12 or 24 volts at start-up based on the battery voltage, so to properly work with 24V panels, the 12V batteries need to be connected together to present a battery voltage of 24V so the PS-30M selects 24V mode. I won't get into the details of how to wire that, but as long you have an even number of 12V batteries, you can wire them up to get 24 V. Note that your load output will also be 24V so you need to be sure your inverter or whatever load you connect can also handle 24V.

No because I believe it is only 12V DC Input you would have to get a model APS2424, APSINT2424 or APSX3024SW which are made for 24V DC Input Power

Yes, but you must wire two batteries together in series to put the unit in 24V mode where it can handle 260 watts. If not, you will exceed its 130 watt capacity in 12V mode. So you can charge one battery with one panel at a time or charge 2 batteries at a time with two panels. Nice setup!

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.

Dont know if i understand your question. But it doesn't sound like it would work because one 12v panel wont charge 24v battery unless you connect two 12v panels in series.

Yes as long as you don't exceed the controllers maximum current output. This unit at 12vdc draws 560milliamps

Zubby,This controller can handle up to 125 open circuit volts input. You can series your panels together to get a theoretical voltage of 96 volts, this will have less voltage drop and give you approximately 10 1/2 amps on the input side of the controller. Your problem is with a 12 volt battery bank your amperages on the output of the controller could exceed 80 amps ( 1000 watts divided by 12 volts equals 83.3 amps ). You would need (2) of these controllers with your present configuration. If it is possible; you could make your 12 volt battery bank into a 24 volt battery bank and get a 24 volt inverter, then you would need only (1) controller.

its a 20 amp controller watts = volts X amps. So, 12 volts X 20 amps = 240 watts, so you can only hook up 2 - 100 watt panels.

The short answer is, "Yes." You could connect the output of the solar panel to a 12 volt battery bank. The battery bank will recharge. HOWEVER, if you don't either monitor or regulate this, you will damage the battery bank from overcharging it. Specifically, if you could manually check on the voltage very couple hours, you could disconnect the solar panel when the voltage reaches full charge. or you could get a charge controller that is wired in between the solar panel and the battery bank. This inexpensive device will both optimize the charging current to the battery and will stop the charging when the battery is full.

The panels can supply greater than 30 volts depending on sun. It is the charge controller (also a voltage regulator) that supplies the charge voltage of 12 or 24 volts depending on how it is set. The more voltage your panels can generate the better.

The instructions doesn't give enough explanation. I called the company for my inverter and asked if solar is compatible with their inverter hooked up to the charge controller. They said to keep the inverter connected to the battery. The only thing I can think of is using a 12 volt light or a small apliance could be connected directly to it instead of using the battery power. If a 12 volt light is connected directly you are taking advantage of the solar imediatly. If the same light was connected to the battery instead, the charge controller doesn't let the solar charge the battery until it drops to a certain voltage. So solar panel isn't being used to its full advantage.

Voltage setting is Automatic. Connect to battery first so Controller can determine the Charging Voltage. Then connect the PV Panels.We usually use 24V Battery Bank, so I cannot say how well it works on 12V.

The controler takes power from source (wind ,solar, whatever ) and outputs to batteries based on how you configure the output either 12,24,48 volt Hope that answers your question

The controller input voltage from your solar panels can be any value up to 100 volts max. You're better off with a higher voltage because it is more efficient at transferring the electricity. The wire doesn't need to be as thick so cheaper and easier to work with.There is a switch to select 12v, 24v, 48v. Make sure to fine tune(lower) the float voltage. It's set too high by default.

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
