can md.2012 be usedto maintain 4 12v. bateries wired in series

I've used it fo 2 31series batteries I think it would depend on the size and condition. It would probably maintain them but I dont think it would adiqilutly charge 4 batteries unless they were small

Probably could maintain them once they have been fully charged by an adequate sized aH charger. Should they become even a little bit discharged, 4x 12volt (car sized) batteries will take a very long time, if at all, with ANY 2 amp battery charger. (undercharging caused sulfation = bad for battery). So what size charger do you need? Experts recommend 10% of battery (aH) amp hour rating, or in other words, if your battery is rated at 50aH, you would need a 5 amp charger, or, 200 aH battery = 20 aH charger. NOTE: You could get by with a smaller less amp sized charger, (say 5% of aH rating) just add more time, to reach a full charge.

Dont wire them in series only parallel if they are 12 volt. Series would requier a 48volt charger

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

You don't actually need a constant 12V. The Gentex memory is non-volatile, so it doesn't get wiped when the power is cut. A switched 12V (like you already have w/factory mirror) will work.

Truthfully, I have not used it with 12V DC but clearly I don't see a reason why will it not work as all it is doing is relaying the signal. Question is whether it can stay awake with 12 volt or not. I am not sure but I am certain it will not cause any damage to the unit by you trying 12 volt input. Hope this helps...

Maybe. Find out if the regulator will overheat with a 12V input. Probably better to use a 5V supply.

This unit is DC powered, so I'm assuming you are referring to a DC powered system where you are wiring directly to a 12V DC power source... try it!

I used mine on a 4 unit - 6 volt battery bank in my RV. If they make a unit for 12 volt batteries I don't know. Contact the manufacturer

I think that is a more sophisticated question as batteries labeled 12v DC have actually both higher and lower voltage. You need to consult someone else. The intention of this machine is not to have uninterruptable DC but rather to supply AC from the outlet or from inverting 12v DC batteries back to DC. I run nothing else off those batteries. You should consult the technical division of Tripp Lite

You can try it, and it should work, the unit has a input side for 48 volts and an out put side delivering a reduced 12 volts, I would not think the unit cares or could determine that the 48 volts was from a charger or 8 or 12 volt batteries in series. I am running all me 12 volt items,lights, horn,radio.

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.....

I don't see why not...12 volts is 12 volts, but I have never tried it. Best to double check.

If you don't know that, I would advise you not to play with these. Transformer is an AC product only, and 12V + 12V is the RMS rating of each independent winding, assuming that you connect the primaries right, which I remember to be 120V + 120V. The primaries in series will make this transformer to be able to accept 240 VAC, with each secondary at 12V. In this mode, if you connect these primaries in series from 120V, the secondary will only give you 6V+6V. 30VA is the total AC power you can get for the secondary.Be careful and SAFE

It should, as long as they ARE in series and the input is within the 10A limit. I would google the wire diagram to check how you connect the controller. I would assume it goes from +ve on one battery and -ve on the other to maintain the series.

No. You will damage the unit. This is a switching power supply designed for a 12v output only.

This is a 12V battery. If you put 4 of them in series you'd get 48 volts, but that's far from optimal.

Don't know, i have not used mine yet.I don't see why you couldn't.You may have to put a diode on the output of each one, i had to do that on 2 Astron 12 v power supplies years ago to get them to play nice together.Hope this helps.Mike

Sure,just wire the 12v supply wire to a 12v switched source instead of the wire that only gets 12 volts when in reverse.
