Can i charge a 12 volt battery and still use the rv 12 volt refrigerator at same time hooked up to it?

If the battery wasn't fully discharged you probably could. The unit may not supply enough current to run your refrigerator though so you might still be discharging the battery and eventually fully discharge it if the situation was prolonged. Check the Genius charger's max current output spec against the refrigerator's current draw to see whether you would be charging or discharging the battery. Your RV's charging circuitry probably provides several times the current of the Genius and would be charging with the refrigerator in operation if the engine is running.

It is not recommend to charge a battery at the same time the battery is being drawn on.

I don't see why not, the charger will not power the refrigerator by itself though.

Not likely. The current rating of the 3500 is 3.5 Amps. Your RV refrigerator probably draws more than that. That means the battery will have to make up the difference while the refrigerator is running. The key is how much current the refrigerator draws and how much it runs.

I have it charging two deep cycle 6 volt battery's wired in series for 12 volts on my camper works great for that. I would think it will charge any 12 volt system, larger would just take longer.

You can do this but it will take a long time to fully charge. With only one generator, you will get about 0.1 amp into your 12V battery.

Yes, but beware, you probably want to charge more than just 1 battery, more like a small bank of batteries. For example, I have mine hooked up to a small bank of 8 SLA 12V batteries giving me about 1500 watts stored to power a 1200 W Inverter for appliances. It's like a solar powered battery pack so that I can work and have phone conversations in the most odd places (no generator noise in the background, just pure silence or nature noises, it's awesome). You'll want a decent charge controller (I bought a 10 Amp controller, which is overkill, but has the better charge-methods and pattern that I wanted). Good Luck!

You can charge your battery. You will need to get a charge controller to convert 24V to 12V. The controller will also prevent overcharging of the battery. Get a controller rated for 10 amps or more. I don't know how long it will take to charge one battery. This is a powerful panel, and would likely charge in one day or less.

Not required, even if hooked up to a generator instead of city/county power. My refrigerator and freezer work fine as well as some battery chargers I had running off the dirty output of a poorly regulating generator but the UPS kept flickering on and off so I had to unplug it.

Yes you can. The charger is designed to recognize a full charge and then will trickle charge so that the batteries stay charged and ready but not overcharged. I am doing the same on mine

Charges two 12 volt batteries at the same time. Using it for my boat trolling batteries.

If you are using your Vanner as an isolator you should be able to connect directly to the isolator to charge both batteries.

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.

Yes, it's for the 12v system. I used it with the Bluesky 25amp controller. Grape Solar tech support is excellent, they helped me to pick everything for the local RV shop to install

You should be able to for either and both together, just remember to have your vehicle running as trying to charge two devices at once can drain your vehicle battery down. This is just an extension of your 12 volt outlet.

Yes. I use mine to keep a deep cycle 12V marine battery charged. 12 volts is just a nominal term for the average target output of a battery used in a 12V system. When fully charged, all batteries exceed their rated voltage.

yes you can. The company tells you to hook up to just one battery and to run your engine but I've consulted with you rv geeks. And they told me they cross connect both starting batteries with the compressor and it worked just fine. So far I just use the rv 400 on the car to run the compressor.

No, it is a stand alone system. You would need to buy an inverter/charger combination same as is found in RV's.

You can try it, but you must bear in mind that if you use a 12v charger on a 6v item you may have more power than you need and you may damage what you're trying to power.

This operates off your 12 volt coach battery. So as long as your coach battery has a charge, the device will work. This does mean however that you need to disconnect your coach battery when the RV is not being used for long periods of time. Otherwise the coach battery will go dead.
