I want to use two 12 volt marine batteries, and keep the system at 12 volts, will that work ok?

Yes, two deep cylcle batteries will work and with this system the charge controller will keep your batteries charged up to 14v and maintain that charge as long as you have sunlight and no current draw on your batteries.
1051495
Yes, but...If you have room for two batteries, it's more efficient to use two six-volt batteries in series rather than your idea if using two twelve volt batteries in parallel. In a parallel installation, the two batteries, even if matched in capacity and age, usually have slightly different charges and the lesser charged battery sucks current out of the other one. So the battery bank tend to self discharge. Two six volt golf cart batteries are your best bet.

Depends on how much you're load is. Two battery s will stay charged no problem if you are not loading and charging at same time. However, once batterys are discharge it will take a half day or so to recharge. If you want a consistent load you will need to get an extra panel or two to do both at same time I have been happy with the bundle so far. I can run a 60 tv or floresant light for 6hr or so off of 1 reg bat.

yes but you need to wire the batteries together the proper way, check the internet for 12 volt to 24 volt dc wiring diagrams you will want to maintain 12 volts not 24, this will extend your draw down time on your batteries

Hook the batteries in parallel: positive to positive, negative to negative to maintain a 12 volt (rather than 24 volt) system. Whether the batteries will stay fully charged using the 100 watt panel will depend on the amount of your "load" and the amount of sunlight available.

Yes - Connect the batteries to the charger in parallel. [The plus (+) from both batteries will land on the load + terminal. The negative (-) from both batteries will land on the output load minus terminal.]This is a very common configuration. You can put as many batteries together as you like in this pattern.Doug Wingfield

That depends. Marine batteries will not last as long as dedicated storage batteries in deep discharge applications, but they're lighter and can deliver more amps for a short time for engine starting than a storage battery.

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! Make sure to follow a wiring diagram for a two battery system, so one battery is not getting the charge and not the other and you will be fine....The controller will provide current until both batteries are completely charged.
1051503
Yes, you have to wire the batteries using the Parallel Wiring method. Actually you can wire 10 batteries parallel and maintain 12 volts. If you were wire the two batteries in a series you would have 24 volts.

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....

Should work just fine, but you won't get the time you would from a deep discharge marine battery. 200 watts is only about 2 amps draw at 110 volts and probably about 15 amps from a 12 volt battery.

Sorry I don't know. I use mine for two 12 volt west marine dual purpose 685 wet cell batteries and it works great.

Yes and no. Its a direct wire to a 12volt source. In my boat a large marine battery.

I have 2 deep cycle marine batteries and they meet my needs I would recommend at least 2 maybe 3 depending on your needs. You should check with the manufactur who was extremely helpful to me.

This unit is for 24V system such as marine application, it will not work in your car which is 12V system

I dont see why not. I am using on a 12 volt sustem for my sailboat. My battery bank is 880 amps

Yes you can hook it straight to the boats 12 volt battery just make sure you use the included fuse.

I bought mine a year ago and have been using a standard 12 Volt battery in my boat. Never had a problem and it does it all. I use it to steer my ipilot troweling motor.

I don't think so. I tried to charge 2 12 volt batteries together for your same reason but that didn't work.
407222
It should I put mine in my houseboat which is a 12 volt system ran off a 12 volt battery

no, this is designed to work with marine batteries, charged by solar panels. I have two of these for two different solar systems and really like the way they work.

All it does is take 12 volts from your batterys and change it to 120 volts AC. I have two and never a problem.
689080
It is 24 volt so you would need 2 deep cycle marine batteries. Any brand would is fine.
1939722
Should work.But i suggest to find 24v DC - AC inverter and hook it directly to your batteries. Converting from 24V to 12V and then to AC voltage is not efficient at all.

I'm sorry, I don't know if this unit will work with a 12 volt system. I would suggest consulting a certified electrician. Best if luck to you.
