Will this panel keep a 12v battery charged while running a small air pump off of the battery?

I can not say for sure. It obviously depends on the amount of sunshine available. Also, do you run the air pump continuously day and night? The charger is designed to recharge between battery uses.

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.

I'm no expert, but I would think so. I have the charge controller charging the battery while an AC inverter pulls from the battery. Should be the same situation.

The nature of your question suggest you are looking for a battery "charger". If this is the case you will need more than the 5 Watts this panel can provide. With the 5 watts provided from this panel, you won't need allot of wiz's bang circuit breakers and meters. This panel dose a great job of keeping a fully charged battery in top shape all by it's self.

No, you provide a 12v battery source. It would probably run for a long time on this battery, and you can get a cheap trickle charger to charge it: UPG UB1280I Sealed Lead Acid Batteries

Does this inverter slowly drain the 12V battery with no load (eg, appliance, such as a water well pump that only runs for few minutes when water pressure is slow, connected to it, but not running)?

this is a small solar panel, it will keep a 12volt car battery charged, I use mine for a 12 volt winch for a boat hoist. you could get a inverter to connect to the battery for 110volt lights.

I plugged this into a 12V (3-cell LiPo) battery and measured current draw. It was taking 75Watts at 11.7Volts, so about 6.4Amps. In a running car the air pump will draw slightly more current, but not enough to overwhelm your charging system. If you have a smaller engine just turn off the headlights, it'll be fine.

I have this on a 6 volt battery and it does keep it charged. I would probably go with the larger one for 12v as this said for 6 volt

indeed it will work very well as a 12v air pump should not draw many amps, is the only concern these are made for low draw for a long period of time ,if that is your 12v air pump this will fit the bill nicely.........

I would not recommend hooking this directly to a solar panel...the pump will be damaged at low output voltages from the panel...instead use the solar panel to charge a small 12V battery that in turn powers the pump. Put a low battery cut-off between the pump and battery to protect the battery. Depending upon how long you want the pump to run a small 6-12 Ah battery would be sufficient for 8-10 hours between charge cycles.

No. Just hook it up directly to the 12volt battery posts. I have owned mine for some time now and it works very well to keep my RV auxilliary battery charged.

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.

You are more likely to over charge the battery with a 12 volt unit. Just ensure the whole solar array is in the sunlight for optimal charging.

Assuming you make the proper connections, the switch should do fine on a 12 V battery pump. My battery pump has the same float switch and is rated for 10 Amps at 125V.

I have used this to keep a 12 volt marine battery fully charged all summer and it worked well. I used a charge controller between the solar panel and the battery. This is the one I used.AGPtek® 30A Solar Panel Power Battery Charge Controller / Regulator 12V / 24V 30 Amp with PWM Type of Charging (Automatic Lighting Control + Time Functions). Of course, you can use any charge controller.

You need to buy a 12 regulator they sell for solar panels so it will not over charge your 12 volt batteries.
