Will this panel work on a 12v system or would it over power the batteries?

Unless one has extensive knowledge of Solar panel and the Battery and Know how Solar Electric Systems work. I Do Not Recommend Charging a Battery without a charge controller. This panel is a 24v panel and will charge a 12v battery provided a MPPT charge controller is utilized. Appropriate MPPT charge controller for this panel would a Morningstar SS-MPPT-15L, this charger can accept up to 36v from the solar array and can charge a 12 or a 24v battery automatically.

Yes. If you read the comment below, you will see that I was/am correct.The panel MAY have a diode, which would prevent it from actively discharging your battery when the sun goes down, but the comment below seems to refute that. The other problem is that this panel will cook your battery, because it will apply voltage and current anytime that light shines on the panel. It will do this regardless of the state of charge of your battery... This will boil the electrolyte, and you'll be left with a 12V paper weight.

Hey Edwars O. Not sure. What type/sort of system are you putting together? 6V 12V? What are you needing to run, and for how long? What are your energy needs? I can't answer your question my friend without more info. I personally use the 400 watt system with another 100 watt panel. I match my batt bank so every 100 watt of solar for 100Ah of storage. Yes, it is over kill for just myself! I'm still in the learning processes if you will. The panels that come with this kit have zero issues with charging the batteries on cloudy days. I'm very happy with this basic system so far!!

I don't know but it should be on 5V. I don't think it can run too long at 12 V.

You won't want to connect the panel directly to a battery, as it could damage or overcharge it. The panel itself only provides a voltage, you need a charge controller between the panel and the battery. The one I used (http://www.amazon.com/gp/product/B001HWQZNQ/ref=wms_ohs_product?ie=UTF8&psc;=1) is not currently available, but should give you an idea of what to look for. You want a controller that can handle at least 30 watts and 17.5 volts input for charging 12v batteries.

Yes BUT... You have to buy a charge controller that can "step down" the 36 volts from the panel to 12 volts for the batteries.Look at Morningstar controllers and or go to Morningstar's website to get the specs on an appropriate controller for your application.

This is not a good option, I'm sorry. I suggest looking for a 10watt 12v panel that discloses the actual specifications of the unit. The output voltage is undisclosed and I had very irregular performance.Hope this helps...good luck.

Without a controller and a battery, the answer is NO because this panel will put out almost 40 volts under no or a light load. With a controller and proper battery, it will do a fine job up to it's rated power.

You can use this controller for 12v but there will be power clipping. The best controller would be the Outback FM-80 for 1KW solar panels charging a 12v battery bank.Thanks, ML SOLAR

Should work if you wire it properly see the following web page on how to wire two 6 volt batteries to equal a 12 volt battery. As the Panel is strictly for charging 12 volt Batteries. you have to make it think the two 6 volts are a 12 volt battery. http://www.solarrvpanels.com/index.php/wiring-rv-batteries-properly/

Of course friend, the panel is high efficiency, full sun generates 22 volts, you need a charge controller 12 Volt so you do not overload the system, it will keep you charged and when the battery is charged, disconnect, which prevents damage to your batteries!

"No" to both. If you have two 6V batteries and hook them up in series, the panel will work. This is a "battery maintainer" and has no sophisticated electronics other than a diode to prevent reverse flow/battery drain at night.

I don't know if this would be good or not for a 12V. I have a adrenalin solar panel on both my Harley and my riding mower. It works great on both and it's about the size of this panel.

This is compatible with a 12volt system as with any solar panel you will require other parts to macke this work saflely and efficiently as a renewable energy system Hope this info helps you Joe

As long as you wire your 3 12volt batteries in parallel, this panel will work. There are built in bypass diodes. But to avoid back flow charging from the battery, you will need either a charge controller and 5Amp is sufficient for the rated current of charge controller.

As far as I can tell, the charging controller is NOT built in to the panel. At only 6 watts, I don't see over-charging a battery unless it is not used from day to day or as late as week to week. However, a small, low cost controller might be a wise investment if you plan to leave the panel charging indefinitely.

You should have at least a basic charge controller to avoid over-charging your battery and possibly damaging it. The panel has built-in diodes to prevent discharging your battery when there's no light on the panel.
