Can it connect directly to a 12 volt battery or does it need some electronics between it and the battery?

unless its got a diode internally yes, otherwise as soon as the wind stops the electricity will go the other way and you've got a fan instead of a generator.

Yes, you can connect directly to a 12 volt battery. No charge controller is needed.

To prolong the life of your battery, I strongly recommend a charge controller. They will keep the battery from overcharge off-gassing. More off-gassing means more maintenance (acid level checks, adding DI water etc). Many batteries don't handle over-charging well.

All spinning devices produce AC electricity, somewhere it has to be converted to DC for use charging a battery. A battery can be overcharged. You can hook directly to it and you can also drive with your eyes closed, it just isn't advisable.

This unit does directly link onto batteries, however you would still need a charge controller.

What a nice girlfriend! Yes, this will need to be hooked up to a 12 volt battery. I am assuming he has a boat to put it in. If that boat has electric start or an electric trolling motor it can be hooked up to either one of the batteries used to start the motor or power the trolling motor.

It comes with an inline fuse so yes, it can be connected directly to the battery. In my case I connected it to an auxiliary fuse block I already had installed.

No, if you connect a 12 volt item to the 48 volts the batteries are putting out the 12 volt item will be destroyed.

no, it needs to be wired directly to the battery with a 30 amp inline fuse added.

Not directly to it. You would need something connected to it with an input.

No..... and maybe.... The point of using the controller is that with small loads less than the rated amperage, when the battery is fully charged, your load is being supplied with power from the solar (bypassing the battery). This allows the charge controller to float charge the battery and also power your device.... If you are drawing lots of power through an inverter, then yes, you will need to connect directly to the battery.... Just FYI - the unit I got had an UN-replaceable fuse.... I had to create a work around to solve the problem....

Correct! you can hook up directly to a 12volt battery. It also(mine did)comes with a lighter plug as an extra option but i never use that...I just run it off of marine type batteries which i recharge when needed.

none. you have to connect the supplied plug to the 12 volts battery of your car.

You can connect it to any DC power source, I spliced mine into the Cig Litter wires that my portable DVD play plugged into. The IR transmitters with line of sight easily worked to the outside of my vehicle.

No, it has to be plugged in. (110 volt outlet to power the 12 volt onboard batteries)

My motor came with a 120 volt connection so you will have to connect 120v directly to the 120v connection

It has a fan that requires attachment to a 12v battery source. We have it wired directly to one of the batteries.

Yes, This can be attached directly to a 12 volt battery. I would suggest running a inline fuse. There is not a power cord on the fan. There is just a little amount of wire off the bottom of the fan and you would run your own wire to make it a clean install.

Yes. You connect the battery with the charge controller. This is only for 12Volt battery. If you have 24volts, you will need to replace the charge controller with a MPPT one.

As others have said, it requires 12v DC. You'll need a power supply for operating it from household power.
